Abstract
The efficacy of low magnification examination of prostatic tissue was assessed. Tissue obtained bv transurethral resection of prostate from 306 cases was screened for carcinoma with a Zeiss DRC dissecting stereomicroscope at 8× magnification. All the submitted tissue from each patient was processed, with at least 1 section cut from each block. There was complete concordance between dissecting microscope diagnoses and those obtained with a standard light microscope at 25× magnification. Use of the dissecting microscope reduced examination time by approximately 80%.
Between 2 and 6 cases of prostatic carcinoma would have been overlooked if various partial sampling protocols had been used in preference to complete sampling of prostatic curettings; therefore the importance of complete sampling of prostatic tissue is discussed. (The J Histotechnol 17:51,1994)
