Abstract:
An 85-year-old woman with gross hematuria for 10 days was presented to Wuxi No.2 People′s Hospital on Dec 10th, 2018.The images showed bladder mass. Pathological analysis of transurethrally resected tissue showed primary malignant melanoma with less pigmentations of urinary bladder. Without any following treatment, it grew again after 17 months. After the second surgery, she died of cachexia half a month later. Primary malignant melanoma with less pigmentations of urinary bladder is rare. It is vulnerable to misdiagnosis without immunohistochemical staining. The prognosis is poor.
