Spectrum of Papillary Breast Lesions According to World Health Organization Classification of Papillary Neoplasms of Breast

Abstract: Introduction Papillary breast lesions are segregated into benign and malignant based on the presence or absence of myoepithelial cells in the papillary cores. Papillary breast lesions are further classified into: intraductal papilloma, papilloma with atypical ductal hyperplasia (ADH)/ductal carcinoma in situ (DCIS), papillary DCIS, solid papillary carcinoma in situ, solid papillary carcinoma with invasion, invasive solid papillary carcinoma, encapsulated papillary carcinoma and encapsulated papillary carcinoma… Show more

“…Identification of histologic characteristics of these tumors on core needle biopsy is critically important (20). Performing core needle biopsy can indicate the nature of papillary lesions as benign or malignant, but it cannot distinguish between invasiveness and non-invasiveness of a tumor (4).…”

“…However, a biopsy is obligatory post-operatively in papillary lesions to expose the risk of peripheral lesion-malignancy (1). This diagnostic path is challenging, and only the existence of resection specimens can provide a definitive answer (20).…”

“…Morphological differentiation in H&E staining has a decisive role in diagnosing EPC/SPC because IHC staining is less helpful. Despite differential points including cystic versus solid and single versus multiple in morphology [ 23 ], some cases on CNB practically exhibit overlaps like a transition from single to multiple ductal lesions and cystic to solid appearance with a gradual cystic filling of proliferation [ 24 ]. Additionally, definitive cut-off criteria have yet to be determined, which may decrease the diagnostic agreement rates among pathologists.…”

“…All specimens were received in 10% buffered formalin. Gross examination of the specimens was conducted according to standard protocols, as described in previous studies [ 16 - 20 ]. The representative sections were taken and submitted from tumor including interface with normal breast tissue and surgical excision margins.…”
