RESUMO
It was reported a case of a 55-year-old woman with giant uterine polylobated leiomyofibromatosis with an albescent-reddish fluctuating nodule, of a mesodermal heterologous mixed tumour aspect. The origin of these sarcomas from müllerian pluripotent mesenchymal cells is discussed. The particularity of this case is underlined by the association of two distinct types of benign and malignant tumours.

The case of a 78-year old man with a non adherent subcutaneous tumour in the right iliac fossa was presented. In about one year and a half it stretched on the third superior part of the fore right thigh and appeared under the shape of a hard plate free from the osseous tissue. Microscopically, besides some fibrosarcomatous proliferations or very slightly differentiated ones with osteoid structures, the predominance of the osteosarcomatous images was found. The problems of pathogenesis and diagnosis of extraskeletal osteosarcomas were discussed.

A case of a 56 years old female patient with a giant tumour of the left pectoral region developed in a 2 years time was reported. The tumour, free from skin and pectoral muscles, was after mammectomy 25 x 15 x 5 cm, 2.200 grs, multilobaed, albescent with hemorrhages zones and predominantly hard, the rest of the breast being extremely reduced in comparison with the volume of the tumour itself. The initial histological aspect was that of a benign spindle cell tumour and only after some neurohistological techniques the diagnosis established was neurofibroma. The literature data and the exceptional mammary localization of this tumour were reviewed.
