Abstract

Inflammatory myofibroblastic tumors (IMT) are distinctive lesions of unknown etiology, composed of myofibroblastic spindle cells with an associated inflammatory background. They can occur in a wide age range and at all anatomic sites, but most frequently they can be observed in the lung (especially in pediatric cases), abdomen, or retroperitoneum. The urinary bladder is one of the most common sites in urological cases. We present a very rare case of IMT of the testis. Clinically, a 40-year-old patient showed a palpable painless lesion of the right testis. Ultrasound examination showed two solid intratesticular foci. During surgical intervention, the intraoperative frozen section revealed mesenchymal tumors admixed with an uncommon inflammatory infiltrate, consistent with a reorganized abscess. Despite the benign result, orchiectomy was performed due to the multifocal presentation and the large size of 3 cm. The final diagnosis was IMT without ALK-rearrangement. Incomplete resection increases the risk of local relapses to 30%. In this case, a complete resection could be achieved and the patient is free of tumor 15 months later.
