Bladder Lymphangioma Treated by Holmium Laser: Extremely Rare Case Report

Introduction: lymphangioma is a sporadic benign tumor of the bladder. it is a congenital disorder and based on the size of lymphatic spaces, it is divided into 3 types of capillary, cavernous, and cystic. case report: in this paper, we presented a 40-year-old woman with microscopic hematuria and a normal urinary ultrasound. urethrocystoscopy showed a flat 4 mm highlighted strawberry-like lesion on the right lateral wall of the bladder. after a cold cup biopsy, the lesion was coagulated by the holmium: yag (ho: yag) laser. conclusion: in bladder lymphangioma based on the size of the lesion, partial cystectomy or minimally invasive surgeries such as laser modality would be the principal treatment.
