Giant renal leiomyoma: A case report

Renal leiomyoma is a rare benign mesenchymal tumor. It arises from the smooth muscle cells of the kidney and renal capsule is its most common location. Small tumor may be asymptomatic and usually appears as a well circumscribed peripherally located solid mass. Large tumor may manifest with pain, palpable flank mass or hematuria. Intersecting fascicles of spindle cells showing immunoreactivity to actin or desmin are characteristic histologic features. We present a case of giant renal leiomyoma in a 20-year-old female with chief complaints of abdominal discomfort and lump in her left side of abdomen. AP radiograph showed a large abdominopelvic soft tissue opacity. Contrast-enhanced computed tomography scan revealed a massive well circumscribed exophytic complex solid cystic mass of size 17 cm × 15 cm × 13 cm arising from upper pole of left kidney. The role of percutaneous biopsy is limited in such lesions and surgery is the only therapeutic option. Keywords: Mesenchymal tumor, Renal leiomyoma, Computed tomography (CT)
