The case of an extragenital heterologous malignant mixed müllerian tumor (MMMT) of primary peritoneal origin occurring in a 76-year-old female is presented. A large tumor was seen between the uterus and rectosigmoid occupying the entire pelvis. The uterus, fallopian tubes and ovaries were uninvolved. The tumor was composed of carcinomatous areas showing endometrioid and serous papillary differentiation and sarcomatous areas showing cartilaginous differentiation. The extragenital primary MMMTs of the female peritoneum are thought to originate from the secondary müllerian system. This case is presented for its rarity. To the best our knowledge, this is the first case of extragenital MMMT of primary peritoneal origin in Indian literature.

UI MeSH Term Description Entries
D010053 Ovary The reproductive organ (GONADS) in female animals. In vertebrates, the ovary contains two functional parts: the OVARIAN FOLLICLE for the production of female germ cells (OOGENESIS); and the endocrine cells (GRANULOSA CELLS; THECA CELLS; and LUTEAL CELLS) for the production of ESTROGENS and PROGESTERONE. Ovaries
D010388 Pelvis The space or compartment surrounded by the pelvic girdle (bony pelvis). It is subdivided into the greater pelvis and LESSER PELVIS. The pelvic girdle is formed by the PELVIC BONES and SACRUM. Pelvic Region,Region, Pelvic

D005187 Fallopian Tubes A pair of highly specialized canals extending from the UTERUS to its corresponding OVARY. They provide the means for OVUM transport from the ovaries and they are the site of the ovum's final maturation and FERTILIZATION. The fallopian tube consists of an interstitium, an isthmus, an ampulla, an infundibulum, and fimbriae. Its wall consists of three layers: serous, muscular, and an internal mucosal layer lined with both ciliated and secretory cells.

D014599 Uterus The hollow thick-walled muscular organ in the female PELVIS. It consists of the fundus which is the site of EMBRYO IMPLANTATION and FETAL DEVELOPMENT. Beyond the isthmus at the perineal end of fundus, is CERVIX UTERI (the neck) opening into VAGINA. Beyond the isthmi at the upper abdominal end of fundus, are the FALLOPIAN TUBES.

D018200 Mixed Tumor, Mullerian A tumor, basically a carcinoma with a single sarcoma such as leiomyosarcoma or angiosarcoma or multiple sarcomas of uterine origin. The role of estrogen has been postulated as a possible etiological factor in this tumor. (Holland et al., Cancer Medicine, 3d ed, p1703) Mullerian Mixed Tumor,Tumor, Mullerian Mixed
