RT Journal Article SR Electronic T1 Extragenital müllerian carcinosarcoma arising from the peritoneum: report of two cases JF International Journal of Gynecologic Cancer JO Int J Gynecol Cancer FD BMJ Publishing Group Ltd SP 764 OP 767 DO 10.1136/ijgc-00009577-200211000-00014 VO 12 IS 6 A1 V.

Mccluggage YR 2002 UL http://ijgc.bmj.com/content/12/6/764.abstract AB Müllerian carcinosarcomas occurring outside the female genital tract are extremely rare but occasionally they may arise from the peritoneum as part of the secondary müllerian system. This report describes two cases of extragenital müllerian carcinosarcoma with heterologous elements in the form of malignant cartilage. We wish to highlight the fact that these aggressive neoplasms may occasionally have a peritoneal origin, similar to primary peritoneal serous carcinomas.
