A 53-year-old woman is referred to the emergency department with complaints of an insidious pain in the left lower abdominal quadrant, with no associated fever, neither changes in her bowel habits, nor other complaints. She had a cardiac arrhythmia, medicated with atenolol, and no previous surgeries. Laboratory results showed no significant changes. Abdominal ultrasound demonstrated an inflammatory mass adjacent to the left colon. The abdominal and pelvic CT-scan showed a bulky and capsulated mass at the left iliac fossa extending along the left flank until the lower pole of the left kidney, measuring 9x12x20cm, probably corresponding to a peritoneal lipoma, with no signs of aggressiveness towards adjacent organs. The patient was admitted to hospital for clinical vigilance and complementary exams. Upper and lower endoscopic studies were performed and revealed no significant changes. The patient was then proposed for elective surgery – laparoscopic excision of the intra-abdominal mass, which was independent of the intra-abdominal visceral content. In the postoperative period, the patient had no complications with clinical discharge four days after surgery. The pathology report revealed a well-differentiated lipomatous neoplasia, a lipoma-like liposarcoma. In a multidisciplinary meeting, it was decided not to perform any adjuvant treatment. The patient remains with neither clinical nor imaging signs of the disease after 10 months of follow-up.
