Inflammatory myofibroblastic tumor (IMT) is an uncommon tumor believed to be benign and can arise in various organs. We report a case of renal IMT in a 74-year old female with right upper quadrant abdominal pain. Computerized tomography showed a 4.5 cm upper pole renal mass, consistent with a renal cell carcinoma. Subsequently a laparoscopic right radical nephrectomy was performed. Pathology revealed an unusual lesion consisting of spindle cells having prominent nucleoli, with plasma cells and lymphocytes throughout the lesion. Staining was positive for anaplastic lymphoma kinase (ALK), vimentin, CK 18, CK-AE 1/3, and CAM 5.2 consistent with an IMT.
