A case of peritoneal free floating calcified fibromyoma.

Giant peritoneal loose bodies are rare and few reported cases are found in literature. These are commonly found in the pelvis. Preoperatively these cases are diagnosed accidentally on abdominopelvic evaluation. We report one such case in a male patient who presented to us with acute gangrenous cholecystitis. We had diagnosed the lesion accidentally on a routine ultrasound of the abdomen and pelvis as a calcified leiomyoma of sigmoid colon. On laparoscopy, it was freely floating in the peritoneal cavity without any kind of peritoneal attachment or attachment to any intraperitoneal organ. The peritoneal loose body was removed by a small abdominal incision. Histopathologically the lesion was reported as benign calcified fibromyoma. Small peritoneal loose bodies are relatively common but a large peritoneal loose body is very rare.
