[Management following mammography revealing grouped microcalcifications without palpable tumor]

On the basis of a series of 60 cases, the authors report their experience of excision of grouped microcalcifications detected at mammography in the absence of any clinical sign. The breast zone in which the microcalcifications were located by the radiologist was removed surgically. Per-operatoire X-ray of the excised specimens using a mammography apparatus confirmed that the microcalcifications had been totally removed. In addition it was useful to locate aceuretaly the calcifications in view of a careful histological examination of the area. The technique led to the discovery of 27 carcinomas at a sub-clinical stage. A classification of the various types of microcalcification was established in relation to histology. It will be of assistance in suspecting malignancy on the basis of mammography findings in the majority of cases. Excision can then be reserved for cases of presumed malignancy or where a doubt exists. By detecting breast carcinomas at a sub-clinical stage, the method makes possible early and minimally mutilating treatment with the best chances of cure.
