ABSTRACT

The objective of this review is to illustrate the broad spectrum of papillary lesions that can be found in breast fine needle aspirations (FNAC).
Papillary tumors of the breast comprise lesions of variable morphology and include entities ranging from benign to high grade malignant. Features of papillary neoplasms invariably describe branching three-dimensional papillary clusters with delicate fibrovascular cords. Cytomorphological criteria for benign and low-grade malignant entities overlap and a definite cytological diagnosis is not always possible. Cellular papillomas may harbor areas of ductal carcinoma in situ (DCIS), atypical ductal hyperplasia (ADH) or lobular neoplasia. DCIS can be both high grade and non-high grade. Immunocytochemistry (ICC) can be helpful, providing there is adequate material for ICC. Relatively high error rates, false negatives as well as false positive diagnoses can be found. In general, papillary lesions may be recognized as such. Reporting strategies will often recommend caution if trying to differentiate benign, cellular papillomas from low-grade carcinomas.
In conclusion, papillary lesions present with a broad spectrum of cytomorphological features that are illustrated in this review
