Abstract

Microglandular adenosis (MA) of the breast is a very rare and benign proliferative lesion, which may be confused with breast carcinoma clinically and pathologically. Several studies have reported a strong relationship between MA and carcinoma arising in MA, so the mass should be excised completely rather than observation. A 49- year-old women incidentally found suspicious malignant lesions in both breasts on screening mammography. Breast ultrasonography revealed bilateral irregular shaped hypoechoic masses with spiculated margins. The results of core needle biopsy were MA in left breast and DCIS in right breast. Due to radiologic-pathologic discordance for the lesion in left breast, we performed additional breast MRI and second look-ultrasound with repeated biopsy. The result of a core needle biopsy was again MA, and eventually confirmed by excision. We report this case of MA, which mimics breast carcinoma radiologically.
