We report a case of transitional cell carcinoma arising in the anterior urethra, a portion of the male urethra ordinarily lined by squamous epithelium. This is the 4th case of transitional cell carcinoma of the distal urethra to be reported. The neoplasm metastasized to superficial inguinal lymph nodes.
In this paper we describe the 16th case in the English medical literature of signet-ring cell carcinoma of the bladder, which occurred in a 65-year-old man who developed widespread abdominal metastases. This case illustrates the characteristic diffuse infiltrative pattern of this neoplasm. In addition to light microscopy, ultrastructural studies were performed.
