Inflammatory myofibroblastic tumor of the small bowel mesentery: an unusual cause of abdominal pain and uveitis.

INTRODUCTION: An inflammatory myofibroblastic tumor (IMT) of the small bowel mesentery with diffuse immunohistochemical staining for the anaplastic lymphoma kinase 1 gene is reported in a patient who presented with abdominal pain and uveitis. DISCUSSION: To our knowledge, only seven cases of IMT affecting the small bowel mesentery have previously been reported in the English literature. The association of IMT and uveitis is a rare phenomenon, previously reported in patients with IMT affecting the head and neck. Surgical resection of the IMT resulted in rapid resolution of the uveitis.
CONCLUSION: IMT should be considered in the differential diagnosis for a mesenteric mass.
