Benign Monoclonal Gammopathyを伴える膀胱癌疑診例

Abstract

A case of macroscopic hematuria from bladder lesion associated with benign monoclonal gammopathy in a 76-year-old Japanese male is reported here. At first histopathological findings, obtained by TU-biopsy, was chronic glandular cystitis, in spite of highly malignant cytological findings of the urine and no improvement of his symptoms even after various conservative therapies. But the clinical course and the association of benign monoclonal gammopathy has suggested the malignant neoplasms of the bladder. So open biopsy of the bladder was performed after a year of follow-up study, and transitional cell carcinoma of the bladder has become to be suspectable histopathologically as well as clinically.
