A large bladder leiomyoma.

Background: Bladder leiomyoma is a rare, benign tumor of the bladder. We present the first large endovesical leiomyoma case report in Indonesia and the largest bladder leiomyoma without any post-operation symptoms.

Methods: A 42-year-old female came with painless hematuria and irritative symptoms in the past year. Cystoscopy and open excision of the tumor showed well-encapsulated papillary solid mass at trigone (7 x 6.5 × 4 cm with a weight of 800 g). Postoperative histopathology confirmed the diagnosis of endovesical leiomyoma of the urinary bladder.

Conclusions: Open excision of bladder leiomyoma had good outcomes on large endovesical mass patients.
