Tumours of the male urogenital tract: a clinicopathologic study.

The present communication deals with the study of 388 tumours of the male urogenital tract diagnosed histopathologically during the period of 1984 to 1990. Of these 12 (3.09%) were benign and the rest 376 (96.91%) malignant. The incidence of malignant growths of male urogenital tract was 8.71% of all the malignancies or 14.19% of all cancers in males. Renal tumours constituted 10.64% of all the malignant tumours of male urogenital tract or 1.51% of all the male cancers. Morphological variants were renal cell carcinoma (37.5%), Wilms' tumour (47.5%), transitional cell carcinoma (7.5%), papillary cystic adenocarcinoma (3.5%), leiomyosarcoma (2.5%), metastatic from thyroid (2.5%). The mean age of the cases for renal cell carcinoma was 50.3 years and for Wilms' tumour 3.5 years. Urinary bladder cancer comprised 29.52% of all the malignancies of male urogenital tract or 4.19% of all malignant growths in males. The average age of the patients was 53.9 years. Transitional cell carcinoma was the commonest type of tumour (91.9%). Primary malignant tumours of the testis constituted 0.95% of all the malignancies, 1.55% of all male cancers, 10.9% of all malignancies of male urogenital tract or 18.3% of all the malignant growths of male genital tract. The mean age of the patients was 40.6 years. Seminoma was the commonest -46.34% of all the testicular tumours. The incidence of prostatic cancer was 1.81% of all cancers, 2.95% of all malignancies in males or 20.74% of all malignancies of male urogenital tract or 34.82% of malignancies of male genital tract.(ABSTRACT TRUNCATED AT 250 WORDS)
