Clinical-radiologic-pathologic characterization of diabetic mastopathy: an analysis of 21 cases

DMP presents a diagnostic paradox of benign mammographic but suspicious sonographic appearances. The characteristic "absence of space-occupying effect" on ultrasound is a key differentiating feature from breast carcinoma. Recognizing this sign, along with atypical patterns like ductal dilation, can increase pre-biopsy diagnostic suspicion in patients with long-standing diabetes, potentially guiding more conservative management. Histopathological confirmation remains essential.
