Mammary carcinosarcoma with osteochondrosarcomatous differentiations.
The case of a 77-year-old woman with a 6/5/4.5 cm, mobile, hard, white-yellowish tumour associated with axillary adenopathy, with a progressive evolution in the upper external frame of the right breast is presented. The histopathological examination, carried out after the radical mammectomy, revealed zones with plates of slightly differentiated carcinomatous cells forming keratose pearls next to dense mixofibrochondrosarcomatous proliferations. The scarcity of these tumors as well as the mammary sarcomas and histogenesis questions are discussed.
