[Fibroblastic rheumatism of the elderly. Histopathological, ultrastructural data and problems of differential diagnosis].

In order to contribute to the knowledge and the nosography of fibroblastic rheumatism, the authors report a case occurring in 68 years old patient. The differential diagnosis of the disease rests on histological and ultrastructural aspects of the dermal and articular tissues where numerous myofibroblasts are observed. On that score, among the acquired adult fibromatoses, fibroblastic rheumatism seems closer to Dupuytren's disease than to sclerodermis.
