[Infantile digital fibromatosis. Anatomo-clinical and ultrastructural study]

About one personal case, authors consider clinical, histological and ultrastructural aspects of the infantile digital fibromatosis. They insist on the caracteristic features of the large granular and fibrillar cytoplasmic inclusions observed in the proliferative fibroblasts, and on the different signs of the metabolic hyperactivity of these cells. Elastogenesis was very scarce within the swelling but showed no evidence of qualitative abnormality. The discussion provides no definitive clue as to the nature or origin of the inclusions.
