症例1:82歳,女性.12年前に糖尿病を指摘され,血糖降下剤の内服をしている.左A領域に22×18mm のdimpling陽性の硬い腫瘤を認めた.腫瘤は超音波では境界不明瞭で不均一な低エコー領域として描出され,マンモグラフィーでは不整形で通常の乳癌と比べ淡い腫瘤影であった.MRマンモグラフィーではenhanceされなかった.症例2:61歳,女性.糖尿病にて15年前よりインスリンを自己注射している.左C領域に28×27mmの不整形の硬い腫瘤を触知した.腫瘤はdimpling陽性で筋膜との癒着を認めた.腫瘤は超音波では不整形で不均一な低エコーで,マンモグラフィーでは不整形の腫瘤影であった. 2 例とも吸引細胞診では上皮細胞を認めず, 穿刺組織診にてdiabeticmas-topathyと診断した.糖尿病患者の乳腺腫瘤では本疾患を念頭に置き,本疾患が疑われた場合は穿刺組織診で診断して不必要な手術は避けるべきであると考えている.

Second Department of Surgery, Nagoya City University Medical School Recently mastopathy of the breast associated with long-term diabetes has been increasingly reported. We report here two patients with diabetic mastopathy. Patient 1, an 82-year-old woman who had been treated as type2 diabetes for 12 years, noticed a mass in the A-region of the left breast. It was a 22×18mm and dimpling-positive hard mass. The mass was suggestive of cancer on palpation and ultrasonic examination. But it revealed lower density than that of cancer on mammography. No enhancement was demonstrated on magnetic resonance imaging. Patient 2, a 61-year-old woman who had been treated with insulin for 15 years noticed a mass in the C-region of the left breast. It was 28×27mm (insize), dimpling-positive and fixed on muscle membrane. The mass was suggestive of cancer on ultrasonic examination and mammography. Aspiration cytology was done on both masses, but reported as “no cellular material”. We performed core needle biopsies, then diagnosed both cases as diabetic mastopathy. It is recommended performing core needle biopsy on masses suspected of diabetic mastopathy to avoid unnecessary operation.
