Classification of prostatic carcinoma according to the criteria proposed by Dhom (1980) takes into consideration structural characteristics and depends to a large extent upon the architecture of tumoral growth (glandular and stromal features). Distinction is to be drawn between prostatic carcinomas having a uniform structural pattern and those whose structural pattern is pluriform, the latter predominating at 54%. Special forms of prostatic carcinoma are very rare, accounting for only 2.3% of cases (Table 11).
