A Case of Pachydermoperiostosis / 대한피부과학회지

ABSTRACT

Pachydermoperiostosis is a very rare genodermatosis that is characterized by pachydermia, digital clubbing and periostosis. It usually occurs during adolescence and the disease is inherited in an autosomal dominant manner. Although the pathogenesis of this disease is still a matter of debate, it is associated with abnormal proliferation of fibroblasts, osteoblasts and endothelial cells and altered proteoglycan synthesis. We report here on a case of pachydermoperiostosis in a 21-year-old man who was diagnosed by the clinical features, skin biopsy and radiological examinations.
