[Acid phosphatase activity in breast dysplasias and in carcinomas of the breast].
The histochemical reactions of acid phosphatase were studied in tissues deriving from normal breasts, from mammary dysplasia, and from breast carcinoma. Acid phosphatase was demonstrated in all cases with more intense activity in breast carcinoma where activity was particularly accentuated in the stroma. In benign tumours and fibroadenosis, phosphatase was prevalently localized in the periductal cells and within the ducts. Exceptions were the cases of fibroadenosis with acute or chronic collateral inflammation where phosphatase granules were located in the stroma also, even though they were always quantitatively inferior to the corresponding localization of cases of breast carcinomas.
