(a) Contrast enhanced MRI radiological analysis. A transverse section shows the tumor (T) anteriorly compressing the uterus corpus (U), cervix (C), and vaginal canal (V), posteriorly compressing the rectum (R). (b) Angiography frontal section image showing that the tumor (T) was nourished from the vaginal artery (VA) and the uterus corpus (U).

The mass did not extend from the uterus corpus, but the findings were insufficient to determine its origin (Figure 2). To determine the tumor origin, an angiography was performed, revealing tumor feeding from the vaginal artery, but not the inferior mesenteric artery or the uterine artery (Figure 2).
(a) Microscopic findings show the tumor with epithelioid short spindle-cell growth without necrosis. Nuclear pleomorphism is mild. No mitotic activity is present. (b) The tumor involves the vaginal smooth muscle layer and originated ( ) from the vaginal wall.

Nuclear pleomorphism was mild, and no mitotic activity was detected (Figure 3). The tumor involved the vaginal smooth muscle layer and originated from the vaginal wall (Figure 3).
(a) Laparotomy findings. A pelvic tumor (T) was not connected to the uterus (U). (b) Laparotomy findings after an abdominal hysterectomy and a bilateral salpingectomy. A pelvic tumor (T) was connected to the vaginal stump (VS), but not the rectum (R).

A pelvic mass was connected to the vagina, but not to the rectum (Figure 4).
(a) Macroscopic findings of the tumor with connected vaginal (V) tissue. (b) The cut surface of a tumor shows occasional nodules of white fasciculated tissue.

Macroscopically, the mass measured 8 x 6 cm and had well demarcated borders, and a cut surface revealed occasional nodules of white fasciculated tissue (Figure 5).
