Buschke-Ollendorff syndrome in a 6-year-old patient: clinical and histopathological aspects of a rare disease.

Acta Dermatovenerol Alp Pannonica Adriat 2020 Mar;29(1):31-33

Department of Clinical and Molecular Sciences, Dermatological clinic, Polytechnic University of the Marche Region, Ancona, Italy.

Buschke-Ollendorff syndrome (BOS) is a rare genetic hereditary genodermatosis characterized by benign skeletal and cutaneous lesions. Skeletal alterations known as osteopoikilosis (OPK) or "spotted bone disease" are asymptomatic areas of sclerosing dysplasia. Two skin lesion patterns have been described because they may be of either elastic tissue (juvenile elastoma) or collagenous composition (dermatofibrosis lenticularis disseminata). Read More

Medallion-like dermal dendrocyte hamartoma: A rare congenital CD34-positive dermal lesion clinically and pathologically overlapping with fibroblastic connective tissue nevus.

Pediatr Dermatol 2019 May 27;36(3):397-399. Epub 2019 Feb 27.

Department of Plastic and Reconstructive Surgery, Teikyo University Chiba Medical Center, Ichihara-shi, Chiba, Japan.

Both medallion-like dermal dendrocyte hamartoma and fibroblastic connective tissue nevus are rare benign dermal lesions composed of CD34-positive spindle cells. Although regarded as different diseases, it is sometimes difficult to distinguish between them due to their clinical and pathological similarities. We present a case of medallion-like dermal dendrocyte hamartoma that could also be diagnosed as fibroblastic connective tissue nevus and propose the possibility of overlap in these diseases.

Novel KHDRBS1-NTRK3 rearrangement in a congenital pediatric CD34-positive skin tumor: a case report.

Virchows Arch 2019 Jan 6;474(1):111-115. Epub 2018 Sep 6.

Department of Dermatology, Unit of Pediatric Dermatology - CHRU Tours, Tours, France.

Cutaneous spindle-cell neoplasms in adults as well as children represent a frequent dilemma for pathologists. Along this neoplasm spectrum, the differential diagnosis with CD34-positive proliferations can be challenging, particularly concerning neoplasms of fibrohistiocytic and fibroblastic lineages. In children, cutaneous and superficial soft-tissue neoplasms with CD34-positive spindle cells are associated with benign to intermediate malignancy potential and include lipofibromatosis, plaque-like CD34-positive dermal fibroma, fibroblastic connective tissue nevus, and congenital dermatofibrosarcoma protuberans.

S M Balaji

Indian J Dent Res 2014 Nov-Dec;25(6):828-31

Director and Consultant Maxillofacial Surgeon, Balaji Dental and Craniofacial Hospital, Chennai, Tamil Nadu, India.

Proteus syndrome is one of the very rare syndromes with occurrence of cerebriform connective tissue nevus. 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.

Section of Dermatology, Children's Hospital of Philadelphia, Philadelphia, Pennsylvania.

Localized changes in cutaneous elastic tissue often manifest with flesh-colored, hypopigmented, or yellow papules, plaques, and nodules. We present five children with clinically similar cobblestone plaques composed of multiple hypopigmented, nonfollicular, pinpoint papules located unilaterally over the upper chest. All lesions first appeared at birth or during early infancy. Read More

Cerebriform connective tissue nevus of lumbar.

J Dermatol 2015 Feb 16;42(2):219-20. Epub 2014 Dec 16.

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

Department of Dermatology, St Helier University Hospital, Surrey, England.

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
