Leiomyosarcoma of urinary bladder with unusual recurrence in intestinal mucosa and peritoneum: a case report.

BACKGROUND

Leiomyosarcomas of urinary bladder constitute rare malignant sarcomas with very few cases reported in literature.

CASE PRESENTATION: Here, we present a case of bladder leiomyosarcoma in a well-preserved female. She failed to respond to standard chemotherapy and had a rapidly downhill course with unusual metastases in anastomotic site and peritoneum soon after surgery. Despite multimodality management including resection of primary and metastatic site, systemic therapy and pelvic radiotherapy, our patient had dismal prognosis with an overall survival of 1.7 years.

CONCLUSION

Leiomyosarcomas of bladder are aggressive tumors and have a very poor prognosis; thus, future research should focus on optimizing more effective treatment regimes.
