Laparoscopic omental mass excision and hematoma evacuation in a 63-year-old man with hemoperitoneum revealed a rare malignant fibrous histiocytoma originating from the omentum.
Case Report (n=1)
This case report highlights a rare presentation of malignant fibrous histiocytoma arising from the omentum and presenting as hemoperitoneum.
Omental MFH merits consideration in unexplained hemoperitoneum; leaves open standardized laparoscopic approaches pending larger series.
Malignant fibrous histiocytoma (MFH) is an uncommon soft-tissue sarcoma that occurs primarily in the extremities and rarely involves the retroperitoneum and abdomen. A 63-year-old man was admitted to the emergency room because of epigastric pain. Computed tomography revealed a large heterogeneous enhanced mass originating from the omentum with hemoperitoneum. The patient underwent laparoscopic omental mass excision and hematoma evacuation. Histological examination of the resected tumor revealed MFH. This case was therefore omental MFH presenting with hemoperitoneum.
