摘      要：BACKGROUND Breast adenoid cystic carcinoma(AdCC)is a rare invasive carcinoma composed of epithelial and myoepithelial *** adenosis(MGA)is a rare benign proliferative lesion consisting of small,uniform,and round glands formed by a single layer of epithelial cells and basement membrane without a myoepithelial cell *** may progress to atypical MGA and carcinoma arising in *** various invasive carcinomas from MGA,AdCC has been rarely ***,we report a case of AdCC arising in *** SUMMARY A 59-year-old woman was diagnosed with a newly developed density on a routine *** density was similar to or slightly lower than that of the breast *** showed an irregular mass with a slightly higher echo than that of *** resonance imaging showed an irregular mass with a similar T1 signal intensity and a slightly higher T2 signal intensity compared to muscles or the breast *** lesion showed heterogeneous internal enhancement with an initially slow and delayed persistent enhancing ***,the tumor was composed of invasive AdCC,in situ AdCC,and *** is composed of basaloid and ductal epithelial cells forming cribriform or solid sheets,or haphazardly scattered small cribriform or tubular *** showed small glands with a single epithelial lining and retained lumen.S-100 staining was strongly positive in MGA *** patient underwent breast-conserving surgery with sentinel lymph node *** Breast AdCC arising in MGA showed unique imaging findings that was different from usual invasive cancer.
