Torsion of lobular capillary hemangioma of greater omentum: A rare cause of acute abdomen

Abstract

Metastatic tumors of the omentum are common. In contrast, the primary tumors of the omentum are very rare. Primary benign tumors of the omentum include lipomas, myxomas, and desmoid tumors. Primary malignant tumors include leiomyosarcoma, liposarcoma, etc. We report here a case of a 32-year-old female who presented to our emergency department with pain in lower abdomen of 1-day duration. The patient underwent laparotomy and was found to have an irregular mass with bosselated surface arising from the omentum that had caused torsion of the omentum. Histopathology confirmed it to be a lobular capillary hemangioma (LCH) of greater omentum. The postoperative course was uneventful, and she has followed up for last 6 months without any recurrence. There is not yet a single reported case of LCH of omentum.
