[Congenital fibromatosis. Anatomical and clinical study on three observations (author's transl)]

Three congenital fibromatosis are studied. Six years later, the subcutaneous and skeletal lesions of the first patient have disappeared with no recurrence. Regression was also observed in the second one, a generalized fibromatosis with skeletal, subcutaneous and almost certainly pulmonary and laryngeal lesions. The last case is now progressing (vertebral lesion) with a vascular invasion, the prognostic of which is unknown. A review is made about microscopical appearance, origin and difficulties in diagnosis.
