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.
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 ...
The microscopic histopathological findings in PB tumor tissues stained with H&E include the excessive proliferation of irregularly shaped, variably sized, ductal epithelial cells, ductal myoepithelial cells, [3] [4] and lipid-laden, foamy intra-cystic histiocytes [5] within the breast's apocrine glands, abnormally widened gland ducts, abundant ...
The microscopic appearance of a nipple adenoma can be mistaken for carcinoma. [1] Other conditions that have similar symptoms and signs as nipple adenoma include Paget's disease of the breast, other intraductal papillomas, ductal carcinoma in situ (DCIS), syringomatous adenoma of the nipple and subareolar sclerosing duct hyperplasia.
LCIS is identified in 1.8% to 2.5% of all breast biopsies (including those that show histologic evidence of other lobular or ductal neoplasia. [13] The incidence of LCIS in women without prior history of breast neoplasia has increased from 0.90 per 100,000 persons in 1980 to 3.19 per 100,000 persons in 1998 – but this is likely due to the ...
Fibroadenoma of the breast is a benign tumor composed of a biplastic proliferation of both stromal and epithelial components. [ 12 ] [ 13 ] This biplasia can be arranged in two growth patterns: pericanalicular (stromal proliferation around epithelial structures) and intracanalicular (stromal proliferation compressing the epithelial structures ...
Ductal carcinoma in situ (DCIS), also known as intraductal carcinoma, is a pre-cancerous or non-invasive cancerous lesion of the breast. [ 1 ] [ 2 ] DCIS is classified as Stage 0. [ 3 ] It rarely produces symptoms or a breast lump that can be felt, typically being detected through screening mammography .
