DISTAL PACHYDERMODACTYLY

An 80-year-old white woman had a 6-year history of enlarging, intrader mal plaques on the distal, volar, and lateral surfaces of the fingers. A biopsy specimen showed whorled, densely aggregated bundles of coars ely thickened collagen within a sparsely cellular papillary and reticu lar dermis. The fibrosis entrapped eccrine sweat coils and focally ext ended into the subcutis. This case represents an unusual, predominantl y acral form of acquired, progressive, cutaneous fibrosis, which we pr opose to call distal pachydermodactyly.
