Dermatol Sinica 15: 98-102, 1997

Pachydermoperiostosis, also known as primary hypertrophic osteoarthropathy is an uncommon syndrome characterized clinically by digita clubbing, periostosis and hypertrophic skin changes (pachydermia). We herein report a case of male patient who has suffered from clubbing of fingers and toes for more than ten years. Hyperhidrosis of palms and soles, and seborrheic dermatitis were also noted during these years. Radiological examinations showed cortical thickening of long bones. A skin biopsy was taken from his left finger and the histopathology revealed hyperkeratosis and thickening of the collagen bundles in the dermis.
