[False positive results in breast diagnosis after treatment].

The authors referring to a case with a false positive diagnosis which recently came to their observation, describe the clinical, mammographic and echographic patterns to be considered in order to reach a differential diagnosis between benign and malignant lesions of the breast, which occur on surgical scars following quadrantectomy and subsequent radiotherapy. In particular, after an attentive research of the data reported in literature and after careful evaluation based on their personal experience, they conclude that the traditional clinical evaluation occupies a very prominent role in the follow-up of patients who underwent breast cancer surgery. They also believe that the diagnostic techniques, undoubtedly useful and necessary, must always be subjected to a critical evaluation in order to avoid, to the maximum, the possibility of diagnostic errors.
