They are presented most frequently in women and must be considered as a differential diagnosis with any bladder tumor. The objective of this study is to present a case of a patient with an incidental finding of a bladder leiomyoma and infrequent location; besides being a rare disease. Case Presentation Female patient of 40 years-old, attends the emergency room for abdominal pain in lower right quadrant. Is valorated by the surgery team, that suspected acute appendicitis and made complementary studies. The axial computerized tomography shows an inflammatory process in the cecal appendix vs appendicular mucocele. The patient was undertaken to appendectomy by laparoscopy. During the procedure, a nacreous irregular lesion dependent on the bladder dome was detected, the urology service was consulted intraoperatory call to the urology service was made. A cystoscopy was made, with no endoluminal lesions identified. An excision of the lesion and appendectomy were made without complications. Pathology of the lesion reported a bladder leiomyoma. Discussion and Conclusion Bladder leiomyomas are very uncommon benign tumors. Most cases are asymptomatic, they are an incidental finding and should always be considered a differential diagnosis of any vesical mass. Images should be helpful diagnostic tool but the gold standard is the histopathological study. The treatment might change according to the size and location of the tumor.
