Breast adenoid cystic carcinoma arising in microglandular adenosis: A case report and review of literature

BACKGROUNDBreast adenoid cystic carcinoma (AdCC) is a rare invasive carcinoma composed of epithelial and myoepithelial cells. Microglandular 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 layer. MGA may progress to atypical MGA and carcinoma arising in MGA. Among various invasive carcinomas from MGA, AdCC has been rarely reported. Here, we report a case of AdCC arising in MGA.CASE SUMMARYA 59-year-old woman was diagnosed with a newly developed density on a routine mammogram. The density was similar to or slightly lower than that of the breast parenchyma. Sonography showed an irregular mass with a slightly higher echo than that of fat. Magnetic 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 parenchyma. The lesion showed heterogeneous internal enhancement with an initially slow and delayed persistent enhancing pattern. Microscopically, the tumor was composed of invasive AdCC, in situ AdCC, and MGA. AdCC is composed of basaloid and ductal epithelial cells forming cribriform or solid sheets, or haphazardly scattered small cribriform or tubular glands. MGA showed small glands with a single epithelial lining and retained lumen. S-100 staining was strongly positive in MGA area. The patient underwent breast-conserving surgery with sentinel lymph node biopsy. CONCLUSIONBreast AdCC arising in MGA showed unique imaging findings that was different from usual invasive cancer.     

A case of adenoid cystic carcinoma of the breast

A 57-year-old woman was referred to our institution 4 months after she noticed a palpable, painless mass in her left breast. Physical examination revealed a mobile and elastic mass. An axillary or subclavicular lymph node was not palpable. Mammography revealed a lobulated mass with a partially ill-defined border. Ultrasonography depicted a 2.5 × 1.5 cm irregularly shaped mass with heterogeneous internal echo and posterior acoustic enhancement. The border of the mass was poorly defined at the anterior and lateral aspects of the mass. Results of ultrasonography-guided fine-needle aspiration cytology were strongly suggestive of a malignant tumor. Thus, the patient underwent breast-conserving surgery with axillary lymph node dissection. The gross resected specimen revealed a gray-to-white and well-demarcated solid tumor measuring 3 × 2 × 2.5 cm, with an irregular border and heterogeneous internal structure. Histological examination showed the characteristic patterns of adenoid cystic carcinoma of the breast. Immunohistochemical studies for both estrogen receptors (ER) and progesterone receptors (PgR) were negative. The patient remains well and has no clinical recurrence of the disease after 5 years of follow-up without radiotherapy or adjuvant therapy.

Primary adenoid cystic carcinoma of the esophagus: a case report.

We report on the case of a 61-year-old woman with a pedunculated esophageal tumor that had a central ulceration. Histology of the resected tumor revealed adenoid cystic carcinoma which was localized entirely in the submucosal layer. The tumor was composed predominantly of solid nests of tumor cells, with some areas showing a cribriform pattern.
