    Papillary carcinomas of the breast (PCB), also termed malignant papillary carcinomas of the breast, are rare forms of the breast cancers. [1] The World Health Organization (2019) classified papillary neoplasms (i.e. benign or cancerous tumors) of the breast into 5 types: intraductal papilloma, papillary ductal carcinoma in situ (PDCIS), encapsulated papillary carcinoma (EPC), solid-papillary ...

    [3] [11] [13] Ultrasonography imaging typically reveals a poorly-defined heterogeneous mass with various small, round, echo-free areas mostly located near the lesions' borders and thereby helps in distinguishing PB tumors from similar cystic lesions such as fibroadenomas, phyllodes tumors, papillomas growing within a cyst, and breast cancer.

    For breast pathology, also in distinguishing usual ductal hyperplasia (UDH) and papillary lesions (having a mosaic-like pattern) from ductal carcinoma in situ, which is usually negative. [1] Cyclin D1 and CK5/6 staining could be used in concert to distinguish between the diagnosis of papilloma (Cyclin D1 < 4.20%, CK 5/6 positive) or papillary ...

    en.wikipedia.org/wiki/Phyllodes_tumor

    It is appropriately named to describe the characteristic papillary projections seen on histology in phyllodes tumors. Phyllodes tumors (from Greek: phullon), are a rare type of biphasic fibroepithelial mass that form from the periductal stromal and epithelial cells of the breast. [1] They account for less than 1% of all breast neoplasms. [2]

    MSC is the most common form of breast cancer in children, [4] representing 80% of childhood breast cancers, [5] although it accounts for less than 0.15% of all breast cancers. [6] (In the pediatric population, about 65% of all breast malignancies are carcinomas. [5])

    en.wikipedia.org/wiki/Intraductal_papilloma

    Intraductal papillomas of the breast are benign lesions with an incidence of approximately 2-3% in humans. [1] They result from abnormal proliferation of the epithelial cells lining the breast ducts. [2] Two types of intraductal papillomas are generally distinguished. The central type develops near the nipple.

  8. Atypical ductal hyperplasia - Wikipedia

    en.wikipedia.org/wiki/Atypical_ductal_hyperplasia

    Atypical ductal hyperplasia (ADH) is the term used for a benign lesion of the breast that indicates an increased risk of breast cancer. [1]The name of the entity is descriptive of the lesion; ADH is characterized by cellular proliferation (hyperplasia) within one or two breast ducts and (histomorphologic) architectural abnormalities, i.e. the cells are arranged in an abnormal or atypical way ...
