Buschke — Ollendorff syndrome in infant patients

The authors present a clinical and histological description of two clinical cases of a rare inherited disease, Buschke — Ollendorff syndrome. In both cases, the disease was not accompanied by the bone tissue dysplasia but at the same time it was characterized by a clear histological pattern specific of this syndrome. The authors provide literature data and discuss issues related to the pathogenesis and particular features of the clinical picture and diagnostics of the disease.

Buschke-Ollendorff syndrome: three generations in a Japanese family

Buschke-Ollendorff syndrome is an autosomal dominant disease characterized by disseminated connective tissue nevi of elastic type and osteopoikilosis. We report a 6-year-old Japanese boy with connective tissue nevi that showed slightly grouped yellowish or skin-colored papules and nodules, distributed from birth over his right thigh, right buttock, and back. Radiologic skeletal survey revealed osteopoikilosis. A skin biopsy specimen obtained from a papule showed that collagen bundles in the dermis were thickened and homogenized. The elastic fibers were not increased but were coarse and clumped. The boy's father, at age 34, has had osteopoikilosis and similar papules and nodules on his left buttock and back for the preceding 18 years. We studied the paternal grandfather, aged 65. He had osteopoikilosis and similar skin lesions on his lumbar region. None of the three had a history of hearing loss or malignant tumor. To our knowledge, this is the first report of three generations of Buschke-Ollendorf syndrome in a Japanese family.

Síndrome de Buschke-Ollendorff familiar

Buschke-Ollendorff syndrome is an autosomal dominant disorder whose clinical course includes elastic nevi and osteopoikilosis. Histologically, most cases present with a normal amount of collagen in the skin lesions and an increase in elastic fibers, although abortive forms with skin involvement have been described, with a decrease in elastic fibers and an absence of bone alterations. We describe the case of a 41-year-old woman with Buschke-Ollendorff syndrome criteria, and that of her 2-year-old daughter who might present an abortive form of Buschke-Ollendorff.
