Inflammatory myofibroblastic tumor, histologically characterized by the presence of bland-locking spindle cells and infiltration of chronic inflammatory cells, is extremely rare in the gastric wall. We report a case of gastric inflammatory myofibroblastic tumor In a 27-month-old boy. The fine needle aspiration biopsy from the mass showed loose clusters or scattered spindle cells and inflammatory cells, predominantly of lymphocytes and plasma cells. The spindle cells resembled fibroblasts or myofibroblasts. Differential diagnosis from benign and malignant diseases involving abdominal cavity was discussed.
