    Clinical Characteristics of Connective Tissue Nevi in Tuberous Sclerosis Complex With Special Emphasis on Shagreen Patches.
    JAMA Dermatol 2017 Apr 26. Epub 2017 Apr 26.
    Department of Dermatology, Uniformed Services University of the Health Sciences, Bethesda, Maryland.
    Importance: Patients with tuberous sclerosis complex (TSC) frequently develop collagenous connective tissue nevi. The prototypical lesion is a large shagreen patch located on the lower back, but some patients only manifest small collagenomas or have lesions elsewhere on the body. The ability to recognize these variable presentations can be important for the diagnosis of TSC. Read More

A punch biopsy demonstrated a dermal spindle-cell neoplasm with variable smooth muscle actin positivity and negative staining for CD34, consistent with myofibroma. Read More

    Zosteriform Collagen Nevus in an Infant.
    Acta Dermatovenerol Croat 2016 Jun;24(2):148-9
    Aslı Aksu Çerman, MD, Şişli Hamidiye Etfal Training and Research Hospital, Dermatology Department, Halaskargazi Cad, Etfal S, Istanbul, Turkey;
    Connective tissue nevi (CTN) are dermal hamartomas characterized by an imbalance in the amount and distribution of the normal components of the extracellular dermal matrix, specifically collagen, elastin, and/or proteoglicans. The term "CTN" was first mentioned by Lewandowsky in 1921 (1), although it was not accepted until the review by Gutmann in 1926 (2). Classification of CTN was established by Uitto et al. Read More

    Agminated Fibroblastic Conective Tissue Nevus: A New Clinical Presentation.
    Pediatr Dermatol 2016 Jul 14;33(4):e240-3. Epub 2016 Jun 14.
    Department of Dermatology, Hospital de la Santa Creu I Sant Pau, Barcelona, Spain.
    Connective tissue nevi are benign hamartomatous lesions in which one or several of the components of the dermis (collagen, elastin, glicosaminoglycans) show predominance or depletion. Recently, de Feraudy et al broadened the spectrum of connective tissue nevus, describing fibroblastic connective tissue nevus (FCTN), which is characterized by proliferation of CD34(+) cells of fibroblastic and myofibroblastic lineage. Only solitary papules and nodules have been described. Read More

    [Mucinous nevus of late onset].
    Ann Dermatol Venereol 2016 Aug-Sep;143(8-9):547-53. Epub 2016 May 16.
    Service de dermatologie, hôpital Jean-Bernard, CHU de Poitiers, 2, rue de la Milétrie, 86021 Poitiers cedex, France.
    Introduction: Mucinous nevus is a rare disease characterized by mucin deposits in the dermis, with only 23 cases reported to date. It belongs to the connective tissue nevus family and is characterized by dermal mucin deposits. Two histological subtypes have been described: pure mucinous dermal nevus (connective tissue nevus of the proteoglycan [CTNP]) and combined mucinous nevus (combined CTNP) associating epidermal nevus with dermal mucin deposits.

The aim of the present manuscript was to present a case of Proteus syndrome in an unusual facial location, which to the best of our knowledge, is being reported for the first time. The unusual occurrence further strengthens the mosaical basis of its etiopathogenesis. Read More

    A New Variant of Connective Tissue Nevus with Elastorrhexis and Predilection for the Upper Chest.
    Pediatr Dermatol 2015 Jul-Aug;32(4):518-21. Epub 2014 Dec 28.

    Department of Dermatology, Wuhan No. 1 Hospital, Tongji Medical College, Huazhong University of Science and Technology (HUST), Wuhan, China.
    Connective tissue nevi represents a kind of hamartoma, and coalescence of the lesions in a cerebriform mode in the lumbar region without Proteus syndrome is rarely seen. Here, we report a 26-year-old woman presenting with nodules and plaques in her left lumbar region of 26 years in duration. Histopathological examination and Masson-trichrome stain showed increased dermal collagen bundles in a haphazard array. Read More

    Ossifying fibroma in Buschke-Ollendorff syndrome.
    J Cutan Pathol 2014 Sep 4;41(9):740-4. Epub 2014 Jul 4.
    Department of Dermatology, University of California, San Francisco, CA, USA.
    Buschke-Ollendorff syndrome represents an autosomal dominant disorder characterized by connective tissue nevi and osteopoikilosis. Cutaneous lesions may contain either predominantly elastic fibers or predominantly collagen fibers or may show both connective tissue components. The disease results from mutations in LEMD3 (MAN1), which lead to enhanced transforming growth factor-β (TGF-β) signaling and resultant changes in fibroblast function. Read More

    A limited form of proteus syndrome with bilateral plantar cerebriform collagenomas and varicose veins secondary to a mosaic AKT1 mutation.
    JAMA Dermatol 2014 Sep;150(9):990-3

    Importance: Proteus syndrome is an extremely rare disorder of mosaic postnatal overgrowth affecting multiple tissues including bone, soft tissue, and skin. It typically manifests in early childhood with asymmetric and progressive skeletal overgrowth that leads to severe distortion of the skeleton and disability. The genetic basis has recently been identified as a somatic activating mutation in the AKT1 gene, which encodes an enzyme mediating cell proliferation and apoptosis. Read More

    Department of Dermatology, Kangbuk Samsung Hospital, Sungkyunkwan University School of Medicine, Seoul, Korea.
    Connective tissue nevus is not a true tumor, but rather a hamartoma involving various components of connective tissue. It presents as a slow-growing, painless, flesh-colored, or pink nodule or plaque that is evident from childhood. While any region of the body may be affected, there is a predilection for the trunk and extremities. Read More

    Eruptive collagenomas.
    Dermatol Online J 2010 Nov 15;16(11). Epub 2010 Nov 15.

    A 24-year-old woman presented with hypopigmented papules of the abdomen that had been present for four years without a family history of similar cutaneous findings or associated medical problems. Histopathologic features confirmed the diagnosis of a connective-tissue nevus that was composed of collagen. Eruptive collagenomas are a rare form of acquired collagenomas, which are characterized by the sudden appearance of asymptomatic papules and nodules on the lower trunk and extremities; the lesions are composed of haphazardly arranged collagen fibers.

    Department of Dermatology, Hospital del Niño Jesús, Tucumán, Argentina.
    This is a follow-up report on a boy with phacomatosis pigmentokeratotica. At the age of 10 years he had, in addition to a sebaceous nevus and a speckled lentiginous nevus, multiple lesions of a collagen nevus localized on the chin and in the lumbar area.

    Isolated plantar collagenoma not associated with Proteus syndrome.
    J Am Acad Dermatol 2008 Mar;58(3):497-9
    Department of Dermatology, Harvard Medical School, Boston, Massachusetts, USA.
    Isolated plantar cerebriform collagenomas are a relatively rare type of connective tissue nevus. They have been suggested to be pathognomonic of Proteus syndrome. However, their presence is now considered to be a major criterion of Proteus syndrome, but the diagnosis of Proteus syndrome also requires the presence of other minor criteria. Read More

    A mild form of Proteus syndrome.
    Pediatr Dermatol 2007 Nov-Dec;24(6):660-2
    Department of Dermatology, Faculty of Medicine, Gazi University, Beşevler, Ankara, Turkey.
    Proteus syndrome is a multisystem disorder and diagnosis has been difficult because of the variability of the syndrome's manifestations. Dermatologists have an important role as cutaneous findings could provide clues for the early diagnosis of the disease. Herein we report a case who had cerebriform connective tissue nevus and lipoma as the sole manifestations of the disease. Read More

A 13-year-old girl had oval-round, soft, painless papules, 5-10 mm in size and a total of 9-10 on her abdomen and flanks. Skin biopsy demonstrated dense, coarse collagen fibers in the dermis and a decrease in elastic fibers. Read More

    Zosteriform connective tissue nevus: a case report.
    Am J Dermatopathol 2007 Jun;29(3):303-5
    School of Medicine, Flinders University of South Australia, South Australia, Australia.
    Zosteriform connective tissue nevus is a rare form of connective tissue hamartomas, which arises from cells of mesodermal origin. 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. There are only 3 reported cases of zosteriform connective tissue nevi in the worldwide literature. Read More
