Although tubular carcinoma has been considered a special-type tumor, [a] recent trend has been to classify it as a low-grade, invasive NOS carcinoma because there is a continuous spectrum from pure tubular carcinomas to mixed NOS [b] carcinomas with tubular features, depending on the percentage of the lesion that displays tubular features.
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 ...
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 ...
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 ...

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.
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 ...
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.
