Inflammatory myofibroblastic tumor is rarely seen in the prostate. Most of prostatic tumors are benign. However, local aggressively invading the adjacent organs and recurrence are frequent. Rarely, the malignant transformation and metastasis occurs, especially in elderly patient. The definitive diagnosis in a small biopsy is challenging. The correct diagnosis preoperatively will help to avoid unnecessary radical prostatectomy. Interval follow up is recommended. Here we reported two cases of prostatic inflammatory myofibroblastic tumor with literature review.
