NONPALPABLE BREAST-LESIONS - DIAGNOSTIC PROCEDURES AND HISTOLOGIC-FINDINGS IN 338 CASES

We report data relative to 338 breast nonpalpable lesions, submitted t o histologic examination on the basis of the integration of radiologic al and cytologic exams. Out of 186 lesions excised on an inpatient bas is under general anesthesia, 164 were ductal invasive carcinomas, 16 d uctal carcinoma in situ (DCIS), and 6 benign lesions. One hundred and fifty-two lesions had been excised on an outpatient basis, under local anesthesia, with the findings of 142 benign lesions, 7 DCIS, and 3 in vasive ductal carcinomas. An adequate integration of diagnostic proced ures would have the aim of minimizing the number of benign lesions sub mitted to frequent radiological exams, and of detecting ''histological benign'' breast lesions with biologic instability.
