ABSTRACT
INTRODUCTION: Prostatic carcinoma (CaP) is globally the second most frequently diagnosed cancer and the sixth leading cause of cancer death in males. The aim of this study is to determine the pattern of histopathological types of prostatic lesions seen in a private laboratory in Lagos, Nigeria. MATERIALS AND METHODS: Histopathological reports of all prostate specimens, which were received and processed by histopathology section of a private laboratory in Lagos, Nigeria, from August 2009 to December 2013 were reviewed. RESULTS: A total of 304 prostatic tissue specimens were received and processed during the period under review. The youngest patient was 32 years old while the oldest patient was 99 years old with a mean of 67.8 years ± 9.5. The most common diagnosis was benign prostatic hyperplasia (BPH) (62.8%), distantly followed by CaP (29.3%), inadequate samples (6.6%), prostatic intraepithelial neoplasia (1%), and metastasis to the prostate (0.3%). The peak incidence was age group of 60-69 years, closely followed by 70-79 years accounting for 38.2% and 36.2%, respectively. Moderately differentiated CaP (Gleason scores [GSs] 5-7) accounted for 58.1% of the cases while GS 7 was the most common individual score and was seen in 32.3% of the CaP cases. CONCLUSION: In this private practice, BPH is the most common prostate lesion. CaP is relatively high and most of the cases have a high GS that portends high mortality in our population. Efforts should be made to increase awareness so as to reduce the mortality.
