Abstract:
Myoepithelial carcinoma is a rare pathological variant, usually expressed in salivary gland. This case report describes a case of pediatric myoepithelial carcinoma in the urinary bladder. A 4-year-old male patient was admitted to a specialized hospital in Lima, Peru for hematuria. A CT scan showed a tumor lesion in the bladder wall, and biopsy revealed myoepithelial carcinoma of urinary bladder. Six courses of chemotherapy + partial cystectomy + radiotherapy was completed. The treatment was defined based on the pathological variant and the tumor location. The patient is currently at 2 years of disease-free survival.
