Extra Gastrointestinal Tumour (E-GIST): A Rare Case of Pelvic GIST

Gastrointestinal stromal tumors (GISTs) are rare tumors that can arise anywhere in the tubular gastrointestinal tract. A 60-year-old male presented with a pelvic mass measuring 12×10cm in diameter. He underwent exploratory laparotomy with excision of the pelvic mass. The mass was found in the pelvis adherent to bowel loop and sigmoid colon, was correctly diagnosed as a Extra Gastrointestinal stromal tumor (E- GIST) at surgery. It should be noted that preoperative diagnosis of E-GIST is uncommon, due to its rarity and the varying clinical presentation. Gynecologists need to be cognizant of extra-ovarian pathology in female patients presenting with an atypical pelvic mass.
