A Rare Case of Diverticulitis With a Colo-Adnexal Fistula.

Diverticulitis is a very common cause of hospitalization in the United States with fistula formation being a common complication. However, a fistula formation between the sigmoid colon and an ovary is an exceptional rarity. We present a case of a 22-year-old female with a colo-ovarian fistula misdiagnosed as a tubo-ovarian abscess after a recent episode of diverticulitis.

Giant Dedifferentiated Gastric Liposarcoma: Largest to Date.

Liposarcoma is one of the most common soft tissue malignancies in adults, accounting for 15% to 20% of all sarcomas. We report a case of the largest dedifferentiated gastric liposarcoma recorded to date in a patient who presented with upper gastrointestinal bleeding. Initial pathology reports indicated a benign cause even after multiple biopsies were performed; only after surgical resection was the diagnosis confirmed.
