A New Variant of Connective Tissue Nevus with Elastorrhexis and Predilection for the Upper Chest Pediatr Dermatol . Proteus syndrome is a classic neurocristopathy because most of the tissues involved derive from the neural crest. The subependymal hamartomas are typically small lesions that lie along the walls of the lateral ventricles, Diagnostic Criteria for Tuberous Sclerosis Complex, Nontraumatic ungual or periungual fibromas, Multiple randomly distributed enamel pits in dental enamel, Cerebral white matter radial migration lines*§, Definite tuberous sclerosis complex – Either two major features, or one major plus two minor features, Probable tuberous sclerosis complex – One major plus one minor feature, Possible TSC – Either one major feature or two or more minor features. To make a diagnosis of PS, one must have all the general criteria and various specific criteria. In Buschke-Ollendorf syndrome, the skin changes may be delayed until adulthood. Connective tissue nevi are hamartomas in which one or several components of the dermis is altered. The cutaneous lesions also demonstrate foci of hyperkeratosis or acanthosis, which have been considered to be secondary (142). Thus, by a single neuroimaging study, it is not possible to distinguish a giant cell tumor from a subependymal hamartoma (60, 62). They most commonly have an elliptical shape with the long axis of the ellipse being perpendicular to the long axis of the lateral ventricle. Papular elastorrhexis is a rare entity, possibly a form of multiple elastic tissue naevi. The final cerebral lesion that is identified in tuberous sclerosis is the cortical tuber. When present, a connective tissue nevus (Fig. The association of Proteus syndrome with HME and CHHL is now explained by common somatic mutations in the PIK/AKT/mTOR pathway (Lindhurst et al., 2011; Lee et al., 2012). In contrast to dermatomyofibroma, plaque-type DFSP shows strong and diffuse CD34 expression. Connective tissue nevus defines a group of hamartomas with increased quantities of dermal collagen and variable changes in elastic tissue (Fig. Patients with more than 10 cortical tubers seem to have a higher incidence of impaired cognition but this may be related to the higher incidence of epilepsy in this group (58). Hellemans J, Preobrazhenska O, Willaert A, et al. This website also contains material copyrighted by 3rd parties. Consequently, a careful search for other stigmata of tuberous sclerosis must be performed in all children with these hamartomas. Although the lesions appear to be primarily subcortical, at this age it is easy to see a curvilinear central extension of the lesion extending centrally towards the ventricular surface. Two other lesions that should be briefly mentioned in tuberous sclerosis are parenchymal cysts and vascular lesions. Cerebral aneurysms appear to involve children disproportionately; definitive conclusions await further studies. Excluding malignant change in nevi or de novo melanoma may be challenging, especially when distinguishing from dysplastic or Clark nevi. A number of cases with connective tissue nevi with elastin accumulation in the skin, in the absence of osteopoikilosis, have also been described (130). [Medline]. On MR, the white matter becomes isointense to the subependymal nodules as myelination proceeds; as a result, the nodules become slightly more difficult to see as discrete lesions and the irregularity of the ventricular wall becomes the most noticeable abnormality. In infants, subependymal hamartomas can be detected by ultrasonography, CT, or MR. Ultrasound shows the lesions as elliptical regions of hyperechogenicity that protrude into the lateral ventricles. 2017 Oct 1;27(5):547-548. doi: 10.1684/ejd.2017.3093. Tuberous sclerosis complex. Similar lesions also may be seen sporadically as solitary growths in acral skin sites. McClung AA, Blumberg MA, Huttenbach Y, Colome-Grimmer MI, Raimer SS. Mutations of two separate genes have been found to cause this disorder. Connective tissue nevi are hamartomas comprising dermal collagen, elastic fibers, or a combination of the two. Central nervous system involvement occurs in about 40%, with cognitive deficit in about 30% (Turner et al., 2004). Proteus syndrome (PS) is a complex hamartomatous disorder consisting of disproportionate, asymmetric overgrowth of any tissue of the body, particularly the skeleton, cerebriform connective tissue nevi, epidermal nevi, vascular malformations, and dysregulated adipose tissue (Cohen, 2005; Biesecker, 2006). Connective tissue nevi are cutaneous hamartomas in which one of the components of the extracellular connective tissue – collagen, elastic fibers, or glycosaminoglycans – is present in abnormal amounts. However, they can be seen on good-quality studies as elliptical lesions originating in the ventricular wall and protruding into the ventricular lumen. They vary widely in number, with any particular patient having as few as one or as many as 30 (51, 66). In some patients, connective tissue nevi of both elastin and collagen type can be found, and some of the lesions seem to be of mixed type, with generalized proliferation of these two fibrillar components of the connective tissue. Diagnosis is often made clinically, but if the diagnosis is unclear, a skin biopsy can be performed. Indeed, fibrous papule, angiofibroma, pearly penile papule, acquired digital fibrokeratoma, and oral mucosal fibroma all form part of the same spectrum, the basic nature of which is fibroblastic with secondary reactive vascular ectasia.171, Laura Flores-Sarnat, Harvey B. Sarnat, in Handbook of Clinical Neurology, 2015. Am J Surg Pathol 2012; 36: 1509–15.. As these cutaneous findings are not unique to the syndrome, both osteopoikilosis and a positive family history are required for a confident diagnosis. Despite similar clinical appearance of many connective tissue nevi, they can be differentiated histochemically and/or biochemically on the basis of the primary connective tissue element present. In adults, hamartomas do not grow. Connective Tissue Nevus: Read more about Symptoms, Diagnosis, Treatment, Complications, Causes and Prognosis. These tumors differ from subependymal hamartomas by their size and their tendency to enlarge; their characteristic location and tendency toward enlargement usually result in a clinical presentation of hydrocephalus (62, 63). There are dense sclerotic bundles of collagen, with an interwoven pattern, in the reticular dermis.720 Fibroblasts appear hypertrophied.720 There is no inflammatory infiltrate or increase in vascularity. Buschke-Ollendorff syndrome (BOS) describes an autosomal dominant condition that encompasses connective tissue nevi and osteopoikilosis. Nevus (or nevi if multiple) is a nonspecific medical term for a visible, circumscribed, chronic lesion of the skin or mucosa. J Cutan Pathol. 2005 May. 7.7). 1979 Nov-Dec;66(6):697-9. Collagenoma, and other connective tissue nevi, are generally diagnosed by appearance of the affected area. The age of onset of a connective tissue nevus depends on the type of lesion. The main differential diagnosis includes plaque-type DFSP, fibroblastic connective tissue nevus, and neurofibroma. Visual Diagnosis: Connective Tissue Nevus and Osteopoikilosis Maria Pereira , Ana Leite , Eduarda Osório Ferreira , Ana Filipa Duarte , Eckart Haneke , Osvaldo Correia Pediatrics in Review Mar 2018, 39 (3) e13-e17; DOI: 10.1542/pir.2016-0213 Paul Krusinski, MD Director of Dermatology, Fletcher Allen Health Care; Professor, Department of Internal Medicine, University of Vermont College of Medicine An unknown percentage of patients with tuberous sclerosis have cyst-like structures, most commonly periventricular, in the cerebral hemispheric white matter. The skin findings of BOS are primarily skin-colored to yellow papules, which may coalesce into plaques. Paul Krusinski, MD is a member of the following medical societies: American Academy of Dermatology, American College of Physicians, Society for Investigative DermatologyDisclosure: Nothing to disclose. Although the regions of ventricular wall around the foramina of Monroe are the most common sites, subependymal hamartomas can be seen in any part of the lateral ventricles, including the frontal horns, occipital horns, and temporal horns. Light and electron microscopy of eruptive collagenoma. The authors and editors of Medscape Reference gratefully acknowledge the contributions of previous authors, Boris Zaks, MD, and Dina D. Strachan, MD, to the development and writing of this article. They usually present as asymptomatic, firm, flesh-colored plaques and nodules, 0.5–5.0 cm in diameter, on the trunk and upper part of the arms.661 The ear,664 sole of the foot,665,666 and vulva667 are rare sites of involvement. Note the absence of inflammation. 1112322-overview On neuroimaging studies, three specific types of lesion are seen in patients with tuberous sclerosis: subependymal hamartomas, cortical/subcortical hamartomas, and subependymal giant cell tumors (60). Ultimately, they are seen as hyperintense lesions compared with surrounding white matter on T2-weighted and FLAIR images and they may be isointense or slightly hypointense compared with surrounding white matter on T1-weighted images (61, 62, 68). Their appearance on neuroimaging studies varies with the age of the patient. In some cases, the lesions consist, in addition to extracellular matrix components, of lipids and have been described on histological basis as elastofibrolipomas (137). Another area with highly collagenized connective tissue. Steven Brett Sloan, MD Associate Professor, Department of Dermatology, University of Connecticut School of Medicine; Residency Site Director, Connecticut Veterans Affairs Healthcare System; Assistant Clinical Professor, Yale University School of Medicine Connective tissue nevi may be present at birth or arise during childhood and can be found anywhere on the body. [Medline]. Diseases & Conditions, 2002 Although they were described initially as adenomata sebaceum by Pringle170 because they have a yellow-tan appearance and were thought to be adnexal in nature, it is now clear that such proliferations are best categorized as angiofibromas. The elastic fibers have a peculiar appearance of globules, either singular or in the form of beaded strings, arranged in a linear fashion. This patchy or mosaic overgrow is not present at birth; it typically starts in infancy, as does the scoliosis (Biesecker, 2006). Calcified cortical tubers sometimes appear bright on T1-weighted images (60), while degenerated tubers may show mild enhancement; such enhancement should not be misinterpreted as malignant degeneration, which is extraordinarily rare (60). The incidence of cognitive impairment ranges from 45% to 82%; most recent publications suggest that the lower number is more accurate (51, 57). 82(4):233-5. They are somewhat more common (15–50) in familial cases than in sporadic cases (47). 1) is almost pathognomonic for Proteus syndrome. Increasing awareness of the condition and use of the new diagnostic criteria have resulted in a revision of the estimated incidence from approximately 1 in 100 000 patients (53) to 1 in 6000 live births (51, 54). The clinical and histologic characteristics of papular elastorrhexis, as well as its differential diagnosis, are discussed. Article PubMed Google Scholar Nevertheless, this separation is artificial at best. Few differences in the clinical phenotype have yet been noted in patients with one mutation as compared with the other (48). 2009 Oct. 36 Suppl 1:35-8. The cutaneous lesions in this disorder are characterized by multiple white papules usually occurring on the trunk. Linear epidermal nevi (keratinocytic) are characteristic; they can develop in several parts of the body but most frequently in the neck. If you log out, you will be required to enter your username and password the next time you visit. Connective tissues are made up of two proteins: collagen and elastin. The vascular lesions are usually arterial aneurysms, which can develop anywhere in the arterial system, including the cerebral vasculature (72–76). Care should be taken not to misdiagnose these as small subependymal hemorrhages. These tend to be nonfollicular and scattered evenly over the affected area. Al-Daraji WI, Ramsay HM, Ali RB. Diseases & Conditions, 2002 Eve mentioned left cerebral enlargement at autopsy, suggesting HME. From: Weedon's Skin Pathology (Third Edition), 2010, Katherine B. Püttgen, Bernard A. Cohen, in Pediatric Dermatology (Fourth Edition), 2013. 2009 Sep-Oct. 26(5):626-8. There is perhaps a bit more telangiectasia in the former of these lesions, and melanin-containing cells are not as notable. [Medline]. The collagen bundles are broad and have a haphazard arrangement.715 Elastic fibers are more widely spaced, but this may represent a dilution phenomenon.715 Sometimes the elastic fibers are thin and fragmented. Histopathologically … Pediatr Dermatol. nevus [ne´vus] (pl. J Am Acad Dermatol. 1. de Feraudy S, Fletcher CD. This lesion typically occurs on … Connective tissue nevi are common, and are facultative but not obligatory; i.e., they may or may not be present. The initial diagnosis may be made … One such example is the dermal nodule found in the sacrococcygeal region of bicycle riders.713, The epidermis is usually normal, although an overlying epidermal nevus has been reported.714 There is thickening of the dermis, sometimes with partial replacement of the subcutis. In contrast to dermatomyofibroma, plaque-type … 2007 Apr. Of interest is the observation that elastofibroma dorsi is particularly prevalent in an area of Okinawa, Japan, and many of these patients have a family history of similar lesions (141).

Dermatofibrosarcoma protuberans – These are usually more cellular and show a storiform growth pattern. Differential diagnosis of fibroblastic connective tissue naevus. Affected patients can have nearly any type of seizure; therefore, the diagnosis of tuberous sclerosis should be considered in any child with epilepsy. Lesions appear in the newborn as 1.0–10 cm diameter plaques composed of fibrotic papules and nodules, which often give a peau d'orange texture to the skin. 1116287-overview Differential Diagnosis. 2002 15.19); CD34 is usually positive, and SMA expression is at most weak and focal. Most of these conditions are asymptomatic and only of cosmetic concern; however, considering the differential diagnosis of other infiltrative processes, a skin biopsy should be performed to confirm the diagnosis of connective tissue nevi of the elastin type. Richard P Vinson, MD is a member of the following medical societies: American Academy of Dermatology, Texas Medical Association, Association of Military Dermatologists, Texas Dermatological SocietyDisclosure: Nothing to disclose. They may be hereditary or acquired. Share cases and questions with Physicians on Medscape consult. The central extension of the lesions becomes much more difficult to see as the brain myelinates; use of magnetization transfer to diminish the Tl shortening effect of the myelin (69) or FLAIR to increase sensitivity to the slight signal alterations (70, 71) may help to identify this finding (Fig. The incidence of elastofibroma dorsi is not known, but this condition, as judged from autopsy findings (140), is relatively common in individuals over 50years of age. Richard P Vinson, MD Assistant Clinical Professor, Department of Dermatology, Texas Tech University Health Sciences Center, Paul L Foster School of Medicine; Consulting Staff, Mountain View Dermatology, PA 2.84). Magnetic resonance imaging is the study of choice for the identification of subependymal hamartomas in neonates and infants, showing elliptical lesions that demonstrate short Tl and T2 relaxation times compared with the surrounding unmyelinated brain parenchyma (60, 61). J Clin Pathol. [Giant cell collagenoma of the bulbar conjunctiva]. It appears that mutations of these two genes make up the vast majority of, if not all, cases of tuberous sclerosis (45–47). These lesions are identical, by histology, neuroimaging, and clinical manifestations, to focal cortical dysplasia with balloon cells, described above (65). 1. Fibroblastic connective tissue nevus (FCTN) is a rare benign cutaneous mesenchymal lesion of fibroblastic/myofibroblastic origin, first described by Feraudy and Fletcher, and almost simultaneously by Saussine et al. Sardana K, Bansal S, Garg VK, Khurana N. Linear nodular collagenoma--successful treatment with intralesional triamcinolone acetonide. The lesions typically present in the first Histologically, subependymal lesions in patients with tuberous sclerosis appear to span a continuum between subependymal hamartomas and giant cell tumors; although some lesions are clearly in one category or the other, many lesions have histologic characteristics of both (51). Nat Genet. In unmyelinated infant brains, the lesions are hyperintense to both gray and white matter on T1-weighted images and hypointense to white matter on T2-weighted images. Coronal T1-weighted (A) and gadolinium T1-weighted (B) images showing evidence of a small subependymal giant cell astrocytoma in the foramen of Monroe. In some families, autosomal dominant inheritance has been suggested (144). Most cases appear to be sporadic and the mode of inheritance is unknown. Nevus (or nevi if multiple) is a nonspecific medical term for a visible, circumscribed, chronic lesion of the skin or mucosa. FIG. Request PDF | On Mar 1, 2018, Maria Pereira and others published Visual Diagnosis: Connective Tissue Nevus and Osteopoikilosis | Find, read and cite all the research you need on ResearchGate Acanthosis nigricans, skin tags, and anogenital anomalies are other features of this syndrome.711 There is a reduction in expression of tuberin in connective tissue nevi associated with the tuberous sclerosis complex.712, Collagenomas must be distinguished from sclerotic fibromas (see p. 815) which present as tumor-like nodules. [Medline]. Although some of these appear to be familial, a number of them are isolated cases with no family history. Dermal dendrocytes are reduced using antibodies against factor XIIIa.716 Calcification was present in one reported case.717, As the collagen in collagenomas is less well packed than normal, differences in polarization colors can be seen with picrosirius red staining followed by polarization microscopy.718 The fibers appear green to yellow, in contrast to the orange to red color of normal dermal collagen.718. One other aspect of giant cell tumors warrants discussion: they rarely degenerate into invasive astrocytomas (51, 63, 64). as “cellular connective tissue nevus”. Among cognitively impaired patients, approximately two-thirds will be moderately to severely impaired and one-third only mildly to moderately affected. Classically, tuberous sclerosis was characterized by the clinical triad of mental retardation, epilepsy, and characteristic skin lesions known as adenoma sebaceum (51). Rare hemorrhagic cases mimic plaque-stage Kaposi sarcoma, which would, however, show positive staining for endothelial markers and human herpesvirus 8.21, Mark R. Wick, in Diagnostic Surgical Pathology of the Head and Neck (Second Edition), 2009. [Medline]. Jouni Uitto, in Emery and Rimoin's Principles and Practice of Medical Genetics, 2013. In one case, however, there was both fibrosis and fibroblast proliferation, leading the authors to suggest that cutaneous mucinosis of infancy could be a pediatric form of papular mucinosis (lichen myxedematosus).144 This is the currently accepted view. FISH studies typically reveal a PDGF/Col translocation. Epilepsy can be severe (Rizzo et al., 1990); however, it is not investigated in many reports and HME is uncertain because of lack of diagnostic study. The TSC1 gene is localized to chromosome 9q34 (39, 40) and codes for a protein called hamartin, while the TSC2 gene has been localized to chromosome 16p13.3 (41, 42) and codes for a protein called tuberin. However, physical trauma to the subscapular area may play a role in the development of these subcutaneous, poorly defined lesions. Patients who have tuberous sclerosis (an autosomal dominant phakomatosis including intracerebral glial nodules, connective tissue nevi of the dermis, and rhabdomyomas of the viscera) may also develop facial or periungual papular lesions that are virtually indistinguishable clinically from fibrous papules on an individual basis.169 However, the tumefactions of tuberous sclerosis arise earlier in life and do not show the topographic restriction or unifocality of the latter proliferations. Undifferentiated connective tissue disease (UCTD) is an autoimmune disease that can affect several systems in the body. sometimes involving the walls of the third or fourth ventricles. Rapidly growing collagenomas in multiple endocrine neoplasia type I. J Am Acad Dermatol. Connective tissue disease (CTD) is classified as undifferentiated CTD when signs and symptoms are consistent with a CTD, but do not fulfill the diagnostic or classification criteria for one of the previously defined CTDs (for example, rheumatoid arthritis or lupus). ne´vi) (L.) a circumscribed stable malformation of the skin or sometimes the oral mucosa, which is not due to external causes; the excess (or deficiency) of tissue may involve epidermal, connective tissue, adnexal, nervous, or vascular elements. 2004 Nov. 36(11):1213-8. [Medline]. 7.7. Pediatr Dermatol. Some lesions are present at birth or develop at the early stages of life (juvenile elastoma) while others develop later in life. They are more difficult to detect on CT in infants than in older children and adults, as they are not yet calcified. The infantile spasms evolve into other seizure types, most commonly symptomatic generalized epilepsy (≈60%) partial epilepsy (≈20%) or a mixture of partial and generalized epilepsy (≈20%) (56). Eur J Dermatol. Especially if concern for tuberous sclerosis, a Wood’s lamp may be helpful in screening for hypopigmented macules or patches. Giant cell tumors also are located in the wall of the lateral ventricle. 60(7):840-2. Connective tissue nevus, Differential diagnosis, Papular elastorrhexis INTRODUCTION Papular elastorrhexis (PE) is a rare cutaneous condition characterized clinically by asymptomatic indurated white or flesh papules mainly on the trunk and extremities and histopathologically by decreased and fragmented elastic Development of collagenomas during pregnancy. Referral to a dermatologist is encouraged if the clinician has any doubts in distinguishing a nevus from a melanoma. Neurofibroma can be separated by immunohistochemistry for S-100 protein.

Fibroblastic connective tissue nevus: the role of histopathological and molecular techniques in differential diagnosis. Thappa DM, Singh A, Jaisankar TJ, Rao R, Ratnakar C. Pebbling of the skin: a marker of Hunter's syndrome. The shagreen patch is a distinct clinical variant of collagenoma, found exclusively in those with tuberous sclerosis. As the white matter myelinates, the appearance of the lesions changes. They are benign lesions that can occur in isolation or in relation to a genetic syndrome such as tuberous sclerosis or Proteus syndrome (Smith and Kirk, 2002). Collagenomas and elastomas generally present during the postpubertal period. 56(5):877-80. Recent experience has shown that half of affected patients have normal intelligence, only 75% have epilepsy, and almost any organ of the body can be affected (52). Fibroblastic connective tissue nevus lacks the uniform plaquelike architecture of dermatomyofibroma, instead being composed of disorderly bundles of bland spindle cells in the dermis and subcutaneous tissue (Fig. 2007 Jul. On CT, they appear in children as foci of low attenuation, typically expanding a gyrus and extending a variable distance into the underlying white matter (60).
