The sonographic appearance of prostatic carcinoma was correlated with the corresponding histopathologic studies in 57 patients after transperineal biopsy. In 21 cases the lesions observed were less than or equal to 2 cm (circumscribed) and in 36 were greater than 2 cm (diffuse). Within the first group there was a prevalence of hypoechoic forms (61,9%). While isoechoic and hyperechoic foci were observed in 14.3% and 23.8%. In diffuse prostatic carcinoma, mixed echogenicity was observed in 50% of patients, hypoechoic in 27.8% and isoechoic in 22.2%. The variations in the appearance of prostatic cancer indicate that sonographic texture is related to the size and histopathologic features of the neoplastic growth.
