[Multiple, continuous and progressive fibromatosis (author's transl)].

Fibromatoses--a subgroup within the group formed by various disorders of fibroblastic origin--have been reviewed. The existence of cases which defy an easy classification has been pointed out. The case of a patient, aged 44, in whom multiple, continuous and progressive tumours, some with considerable invagination, have kept appearing since the age of 10, has been reported.
