Abstract
|
|
|
Eleven cases of primary prostatic cancer among 54 pathologically examined prostates were presented and discussed their clinicopathologic characteristics with review of literature, because of the rarity of occurrence and the paucity of the reports in Korea. According to the incidence, 20. 4% of the prostatic enlargement were malignant nature and the prostatic malignancy was responsible for 0. 53% of 2068 male cancers which were diagnosed pathologically during the same period.
Seven of the eleven prostatic cancers were carcinomas with the average age incidence of 65. 1 yearold, and all were glandular histologically. Three cases of the prostatic carcinomas were probably latent, because there was neither clinical evidence of prostatic malignancy nor any metastatic signs and symptoms, and all the three had morphological patterns of intracystic papillae and closely packed small glands.
Serum acid phosphatase was elevated over the upper limit of normal range in 4 prostatic carcinomas where the anaplastic cells were extremely closely related or invaded the blood vessels resulting in hemorrhage, and three of them represented metastases clinically and/or pathologically.
Four of the eleven prostatic cancers were sarcomas. Three of them were leiomyosarcomas present in 11, 56 and 50 year-old patients and the remaining one was embryonal botryoid type of rhabdomyosarcoma observed in 10 year-old patient.
