Pure Primary Ovarian Squamous Cell Carcinoma Perforating the Rectum

Abstract EN

Rectal perforation is uncommon in ovarian cancer, even in advanced stages.

Pure primary ovarian squamous cell carcinoma is a very rare subtype of ovarian cancer and has not been reported to cause rectal perforation.

A 50-year-old woman presented with rectal bleeding.

Rectosigmoidoscopy suggested perforation of a pelvic tumor into the rectum.

Abdominopelvic magnetic resonance imaging revealed a 9 cm heterogeneous mass in the pouch of Douglas.

We performed complete cytoreduction, including an en-bloc resection of the tumor and rectosigmoid colon.

Histopathology showed squamous cell carcinoma of the left ovary penetrating the rectal wall.

A common symptom of rectal bleeding was caused by a very rare entity of ovarian cancer penetrating the rectal wall, but thorough evaluation led to its accurate diagnosis and appropriate treatment.
