[Cervicobrachial fibromatosis presenting in the mother and the child simultaneously]

Fibromatosis is the proliferation of connective tissue with local infiltrative growth and a tendency to relapse in contrast with fibrosarcoma which never produces metastases. Two patients, a mother and son diagnosed with fibromatosis of initial cervical location in whom surgical extirpation and complementary radiotherapy were performed. The mother underwent polychemotherapy (adriamicine plus dacarbazine) because of extensive relapse. Definitive resolution was achieved in both cases.
