RESUMO
The authors examined the fine structural alterations of palmar aponeurosis in Dupuytren's contracture. Two types of the fibroblasts can be identified: classic fibroblasts and myofibroblasts. In the Dupuytren's tissue one fourth of all non-inflammatory cells were regarded as myofibroblasts. In the Dupuytren's aponeurosis the orientation of the thin and thick collagen fibers varied. The Paccini corpuscles were hypertrophised and around them compact collagen tissue was increased.

A 39 year old patient had suffered from a dermatitis at his neck, partly affecting the face as well, 11/2 years ago. A temporary improvement had been followed by signs of actinic reticuloid: lichenoid eruptions on the erythematous skin associated with pruritus. Patch and photo-patch tests were negative. Histology revealed innumerable capillaries and several macrophages carrying melanin, apart from so-called "Sézary-like" cells.
