"A 43-year-old woman presented with a palpable hard mass in the left breast. Physical examinationrevealed a 1.0×0.8 cm, nontender, and firm ovoid mass. A mammogram revealed a focal asymmetric densityin the left breast that was suspected of being a carcinoma. Ultrasonography of the left breast showed a12.0×7.5×6.5 mm, poorly defined hypoechoic mass with irregular margins and posterior acoustic shadowing.Fine-needle aspiration cytology revealed benign cells.We performed a mammotome probe to make a definitediagnosis, which showed tubular carcinoma. The patient underwent breast conservation surgery (Bp＋Ax).The histopathologic examination revealed well-differentiated tubular carcinoma.Immunohistochemical stainingshowed that estrogen receptors and progesterone receptors were positive,while human epidermal growthfactor receptor type 2 was negative. After the operation, she received endocrine therapy for 5 years. She isalive without any residual or metastatic disease 90 months after being diagnosed.Shinshu Med J 59 : 327―330, 2011"
