Abstract

Summary: We report a case of a 47‐year‐old woman with a history of acral lentiginous melanoma, left great toe subungual primary, metastatic to the lungs, brain, and spleen, presenting with lower urinary tract symptoms. She had also palpated and removed a dark mass from her vaginal canal. Magnetic resonance imaging (MRI) showed polypoidal lesions within the urinary bladder and the endometrium. The suspected differential diagnosis was endometrial and bladder melanoma metastases, based on her cancer history and MRI findings. The patient underwent cystoscopy with transurethral resection of the bladder tumor and endometrial biopsy, and pathology was consistent with metastatic melanoma. Bladder and endometrial metastatic lesions are exceedingly rare. Herein, we describe an unusual case of metastatic melanoma concurrent to the urinary bladder and endometrium.
