Spectrum of Papillary Lesions of Breast: A Case Series

Papillary lesions of the breast are heterogeneous group of intraductal proliferations of epithelial cells with arborescent brovascular cores that have overlapping clinical manifestations and histomorphologic features.(1) But as they have divergent biological behavior these instigate diagnostic challenge to the pathologists. Moreover high rate of discordant interpretation, complexity of the lesions, conicting criteria and simmering controversies pose difculties especially on core needle biopsy material and immunochemistry is necessary and very useful for accurate diagnosis. In this study we present all papillary lesions for 3 years between 2019 and 2021 with special mention on usefulness of immunohistochemistry in diagnosing DCIS and encapsulated malignant lesions.
