@entity2909 ( @entity2909 ) may appear throughout the entire gastrointestinal tract but are rarely seen in the @entity694 and only 5 of those measured greater than 15 cm in diameter. @entity158 and palpable abdominal mass are the most common symptoms. Surgical resection is the treatment of choice for most @entity2909 . We here describe a case of a 46-year-old @entity1 who presented with a 3-month history of @entity490 associated with worsening @entity1142 and abdominal distension. A pelvic solid, polylobulate, left-sided mass was noted on examination. Preoperative findings revealed a dishomogeneous sigmoid mass with calcified spots compressing small intestine and bladder. At laparotomy, a large polylobulate and well-circumscribed mass arising from the descending colon mesentery and displacing small intestine, uterus, and ovaries. A segmental colon resection was performed. An extraluminal 18- * 12- * 5-cm paucicellular sigmoid @entity694 was histologically diagnosed. Our case is one of the few giant (>15 cm) sigmoid colon @entity2909 reported in the literature. Although rare and benign in nature, @entity2909 of the colon can cause life-threatening complications that could require emergency treatment and they should be included in the differential diagnosis of large abdominopelvic masses. Follow-up after surgery is necessary for @entity5 with any atypia or mitotic activity.
