Incidental Carcinoma of the Prostate: Diagnostic Second Transurethral Resection and Therapeutical Consequences
The concept of incidental carcinoma includes a range of tumors with varying degree of malignant potency. This must be kept in mind when evaluating histopathological results and drawing clinical conclusions. It is obvious that the diagnosis of an incidental prostatic carcinoma is related to the exact and complete histological examination of all prostatic material resected [2, 3, 15, 18, 19, 21, 24]. Routinely in our clinic the resection material is prepared as follows. We embed 5 g tissue per block in paraffin; the number of blocks is thus dependent on the amount of material resected. If a carcinoma is found in one block, all material in subsequent blocks is analyzed. The spread of tumor, the number of foci involved, and the grade of malignancy are determined [4, 24]. All incidental prostate carcinomas diagnosed in our clinic are classified according to Jewett . A1 tumors are unifocal and well differentiated; A2 tumors are either multifocal and well differentiated or unifocal and poorly differentiated.
