Abstract

Most bladder tumors are derived from the urothelium. Benign mesenchymal tumors are rare. Leiomyoma of the bladder is the most common benign neoplasm. A case of leiomyoma of the bladder presented here with confusing finding on imaging, ultra sound and I.V. urography..

Highlights

Leiomyoma of the bladder is an uncommon benign tumor[1] approximately 200 cases were described in the literature,[2] it is the most frequent benign neoplasm accounting for 0.43 % of bladder tumors, the etiology of this tumor remains unknown
It is proposed that leiomyomas may arise from chromosomal abnormalities.[1,2]
Behavior of leiomyoma of the bladder is by definition, completely benign.[6]

Summary

Introduction

Leiomyoma of the bladder is an uncommon benign tumor[1] approximately 200 cases were described in the literature,[2] it is the most frequent benign neoplasm accounting for 0.43 % of bladder tumors, the etiology of this tumor remains unknown. It is proposed that leiomyomas may arise from chromosomal abnormalities.[1,2]. 75% of the patients are young or middle aged.[3] It is described as occurring at endovesical, extravesical, and intramural locations.[4] The tumor is usually asymptomatic unless urinary tract function is affected in symptomatic cases common presenting features are usually obstructive in nature.[5] Behavior of leiomyoma of the bladder is by definition, completely benign.[6]
