A 23-year-old female patient consulted for a 3-cm fibroelastic intergluteal tumor with progressive growth in recent years. She did not present suppuration or intestinal/urinary disorders. Rectal examination revealed slight posterior bulging, with no endorectal alterations.
Ultrasound and pelvic magnetic resonance imaging identified a multilobulated mass with well-defined borders adjacent to the rectum, which extended outside the pelvic cavity through a midline defect that was caudal to the sacrum, compatible with a retrorectal cystic hamartoma with extrapelvic extension. The lesion was excised using an abdominosacral approach, and the pathological study confirmed the diagnosis (Fig. 1).
