On physical examination a large abdominal tumor was found. An ultrasonographic evaluation disclosed a giant mass with a mixed content, of approximately 40 x 17 cm size. Two days latter a celiotomy was done, finding the tumor mass depending of the great omentum, with high vascularity and no evidence of metastasis. A complete resection was performed.
