Abstract
The patient was a 71-year-old man referred to our department because of asymptomatic gross hematuria. Detailed examination led to a diagnosis of bilateral ureteral cancer and prostate cancer. Total nephroureterectomy was performed for bilateral ureteral cancers on separate occasions, while prostate cancer was managed with hormone therapy. Because multiple bladder tumors were found by cystoscopy conducted after 3 months, total cystectomy was performed. Neither distant metastasis nor local recurrence had developed, 2 years later, when the patient visited our department again because of glans enlargement and received a diagnosis of penile cancer. Partial penectomy was performed, and a 1-cm indurated nodule was found in the skin of the hypogastric region during surgery and treated by simultaneous wedge-shaped excision. Histopathologically, the lesions were urothelial carcinomas. Multiple metastatic foci occurred in the skin postoperatively centering on the hypogastric region, growing rapidly and accompanied by bleeding and exudate causing a bad odor. Topical application of Mohs paste resulted in dramatic improvement of the pain and exudate, which thereby improved the patient's quality of life (QOL) to a level enabling discontinuation of narcotic drug therapy for cancer-related pain. Thereafter, hepatic metastasis was found and chemotherapy with gemcitabine and paclitaxel was administered. The patient did not respond to this chemotherapy and died of cancer 3 months later. Cutaneous metastasis of urothelial carcinoma, which is a very rare condition, is often managed with palliative therapy due to the lack of response to anticancer chemotherapy. In such cases, the use of Mohs paste appears to be of great value for maintaining the patient's QOL which otherwise might deteriorate markedly.
