乳腺部分切除術  partial mammectomy
骨軟骨化症  osteomalacia
A 43-year-old woman presented with a palpable hard mass in the left breast.
Physical examination revealed a 1.0×0.8 cm, nontender, and firm ovoid mass.
A mammogram revealed a focal asymmetric density in the left breast that was suspected of being a carcinoma.
Ultrasonography of the left breast showed a 12.0×7.5×6.5 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 definite diagnosis, which showed tubular carcinoma.
The patient underwent breast conservation surgery (Bp＋Ax).
The histopathologic examination revealed well-differentiated tubular carcinoma.

the possibility of phyllodes tumor cannot be completely excluded

Although the patient was diagnosed with mastopathy by needle biopsy, lumpectomy was performed because the possibility of phyllodes tumor could not be denied based on the the image.
