Abstract:
About 600 cases of urethral carcinoma have been reported. Such tumors may arise from the surface epithelium or any of the glands, and four histologic patterns--squamous, transitional, glandular, and undifferentiated--have been recognized. Metastases from other sites are possible, as are melanomas and various types of sarcoma.
