Endometrioid carcinoma is a common tumor of the female genital tract, mainly affecting the uterus corpus and ovary. In the fallopian tube, endometrioid carcinoma is relatively uncommon. The female adnexal tumor of probable wolffian origin (FATWO), although occasionally seen elsewhere, is most typically encountered in the broad ligament. Endometrioid carcinoma of the fallopian tube resembling FATWO is a rare type of endometrioid carcinoma, and only 20 cases have been reported to date. Here, we report a case of endometrioid carcinoma of the fallopian tube resembling FATWO and review the literature. A 67-year-old woman presented with a history of prolapse for about one month outside the vulva. Physical examination and pelvic ultrasonography of the patient revealed a streak mass covering the left ovary. A total hysterectomy and a bilateral salpingo-oophorectomy were performed. The tumor was confined to the tube and strongly resembled FATWO. Immunohistochemically, the tumor cells were positive for AE1/AE3, epithelial membrane antigen (EMA), and p16, but negative for CD10, inhibin-alpha, calretinin, vimentin, myogenin, and desmin, CD99,CgA, and Syn. We review the previously published cases of endometrioid carcinomas of the fallopian tube resembling FATWO, and discuss the principal differential diagnosis of the tumor in the fallopian tube.

Cervical plasticity is partially attributed to subepithelial stromal cells. Knowing this population of cells in its variable physiologic states, with its immunophenotypic variations, will lead to better understanding of neoplastic processes related to these stromal cells. We reviewed slides of cervices from premenopausal, postmenopausal, and postpartum patients and used mesenchymal immunohistochemical stains. Results demonstrate 2 distinct subepithelial compartments, within the ectocervix and the endocervix/transformation zone. The endocervix/transformation zone has twice the number of stromal cells as the ectocervix, regardless of age. Ectocervical stromal cells are desmin+/smooth muscle actin (SMA)-, and endocervical stromal cells are desmin+/SMA-. In postpartum/premenopausal patients, the cervix has less desmin+ ectocervical and SMA- endocervical cells. In postmenopausal/prolapse patients, the cervix has no desmin+ ectocervical cells. Desmin+/SMA, calponin, caldesmon, myogenin, myoD1, CD34- cells could represent unusual myofibroblasts that should not be confused with a neoplastic process, especially if a mass is not present.
