Background: Primary renal leiomyoma was confirmed as a rare benign tumor formed by smooth muscle fibers and usually asymptomatic. Purpose: to describe a subcapsular cortical renal leiomyoma with probable vascular origin. Materials and methods: case report of a patient with pain in the left flank with imaging exploration (ultrasonoangiography, abdominal CT and MRI) and microscopic and immunohistochemically postoperatively evaluation. Results: a well-defined solid nodular tumor of about 40mmx50mmx45mm was observed in the upper polar renal cortex, beneath the renal capsule. The tumor mass was poorly vascularized, non-invasive and of benign aspect, hypoechogenic and isodense with renal cortex, with hypo intense heterogeneous signal in T2-weighted image, with fibrous/muscular aspect, and central hypodense area (potential necrosis). Histopathology (fusiform bundled smooth muscle cells) and immunohistochemistry of the tumor cells (positive to actin and negative to MB45) supported the diagnosis of renal leiomyoma. Postoperative evolution was normal at 3 months with no recurrence. Conclusions: Histopathology results confirmed the vascular origin for subscapular leiomyoma. Intratumoral necrosis is associated to degenerative lesions of the muscle fibers. The present tumor mass had an absolute surgical indication. [ABSTRACT FROM AUTHOR] |
