Bladder-sparing Approach in a Woman with Muscle-invasive Primary Bladder Melanoma

Primary bladder melanoma (PBM) is an extremely rare tumor. Herein, we present a 39-year female evaluated for a history of dysuria and hematuria for one month and a solid mass of 23x15 mm detected on the left lateral wall of the bladder. The transurethral resection (TUR) of the tumor revealed muscle-invasive malignant melanoma. Laparoscopic partial cystectomy (LPC) and bilateral pelvic lymph node dissection (BPLND) were performed since other sites of melanoma were excluded. In this article, the effects of tumor characteristics and minimally invasive treatment options on survival are discussed in a patient with muscle-invasive PBM.
