[Case of Ductal Carcinoma In Situ of the Nipple in a 93-Year-Old Man].

ABSTRACT

We report the case of an elderly male patient with ductal carcinoma in situ(DCIS) of the nipple. A 93-year-old man visited the hospital because of pain and bleeding in and swelling of the right nipple. A benign tumor was suspected, but a definite diagnosis could not be made before surgery based on echo and cytology findings; thus, a malignant tumor could not be ruled out. He underwent partial mastectomy combined with the areola and nipple for diagnosis and treatment. Histologic examination confirmed the diagnosis of DCIS of the nipple. The surgical margin was negative. At 6 months after the surgery, he was doing well with no evidence of disease in the absence of postoperative adjuvant therapy. Thus, clinicians should consider breast carcinoma of the nipple as a differential diagnosis when an elderly man presents with swelling of the nipple.
