Abstract

With increase in the population of elderly male, the prostatic pathology has gained a separate domain of its own. Prostatic lesions on routine sometimes cause a diagnostic dilemma especially when malignant tissue is limited and is mixed with benign prostatic glands. Aim: This study is aimed to evaluate a complete spectrum of various prostatic lesions with emphasis on the benign mimickers like, Basal Cell Hyperplasia (BCH), inflammatory atypia,atrophy and adenomatous hperplasia. Material and Methods: The present study was a hospital based 10 year retrospective study carried out in the department of Pathology, KIMS Hubli . The materials for the study included histopathology slides and blocks from 315 cases which constituted 0.72% of all the specimen samples received during the study period. Results: The peak age at which the patients underwent prostetectomy was from the 6th to 8th decade.Benign Prostatic Hyperplasia( BPH) was the major histopathological diagnosis comprising of 90.1% cases , followed by adenocarcinoma in 6.7%, atrophy 1.9%, Prostatic Intraepithelial Neoplasia (PIN) 1.0% and 0.3% of metastatic deposits of transitional cell carcinoma. The associated lesions with BPH were, inflammation in 17.1%, basal cell hyperplasia in 11.7% and atypical adenomatous hyperplasia in 0.4% case. There were 1.9% cases of atrophic prostate. Conclusion: The study of prominent histopathological changes of senescence and the features of co-morbid prostate pathology are of great importance. A systematic approach is necessary to evaluate the lesions of prostate and to detect the mimickers of malignancy.
