Hemoperitoneum secondary to perforated inflammatory myofibroblastic tumor: A case report of an unusual complication.

INTRODUCTION: Inflammatory myofibroblastic tumors (IMT) are rare neoplasms characterized by a proliferation of spindle-shaped cells with a stroma infiltrated by macrophages, lymphocytes and plasma cells. CASE REPORT: We report a case of 59 years old male who presented an acute abdomen due to a mass of the mesentery of the terminal ileum, which was perforated with active bleeding. Histopathology reported a low-grade TMI with clear margins. DISCUSSION: Inflammatory myofibroblastic tumors of the mesentery are rare entities whose etio-pathogenia remains unclear. It requires a histopathological diagnosis and inmunohistochemical evaluation and its treatment is based on complete resection of the tumor. These type of neoplasms require close monitoring due to local recurrence.
