title: Mucinous carcinoma of breast with abundant psammoma bodies in fine-needle aspiration cytology: a case report.
abstract: Fine-needle aspiration (FNA) cytology plays an important role in the diagnosis of various pathologic conditions in the breast. Microcalcification can be observed in benign and malignant breast lesions, but psammoma bodies (PBs) are rarely reported in breast lesions and are a feature of papillary neoplasms. However, we have observed PBs in large numbers in a mucinous carcinoma of breast, which is not previously reported in FNA of breast lesions. A 65-yr-old postmenopausal woman underwent FNA of a palpable mass. The aspirate revealed mucinous carcinoma cells associated with plenty of PBs. This case report of mucinous carcinoma of the breast with abundant PBs highlights the cytodiagnostic pattern of the lesion and formation of PBs.
