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.
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.
A papilloma (plural papillomas or papillomata) (papillo-+ -oma) is a benign epithelial tumor [1] growing exophytically (outwardly projecting) in nipple-like and often finger-like fronds. In this context, papilla refers to the projection created by the tumor, not a tumor on an already existing papilla (such as the nipple).
Florid cutaneous papillomatosis (FCP) is an obligate paraneoplastic syndrome. FCP begins as the sudden onset of numerous cutaneous papillomas that are clinically indistinguishable from viral warts. The papillomas range from 1 to 3 mm in diameter may spread to involve the entire body, including the face.
Inflammatory papillary hyperplasia (IPH) is a benign lesion of the oral mucosa which is characterized by the growth of one or more nodular lesions, measuring about 2mm or less. [ 4 ] [ 5 ] The lesion almost exclusively involves the hard palate, and in rare instances, it also has been seen on the mandible.
Usual ductal hyperplasia (UDH) is a benign lesion of the breast wherein cells look very similar to normal. It is a spectrum of changes that can range from minimal stratification of cells to proliferations that are just short of atypical ductal hyperplasia .
Because the hyperplasia of PNE cells can be seen as a reaction to chronic lung disease, surrounding solitary bronchial carcinoids and adenocarcinoma of the lung, these causes must be excluded prior to a DIPENCH diagnosis. [1] Obstructive bronchiolitis has been reported as a characteristic histopathologic finding in patients with DIPNECH. [8]
Histopathologic types of breast cancer, with relative incidences and prognoses. "Lobular carcinoma in situ" is at right. LCIS is identified in 0.5% to 1.5% of benign breast biopsies. These biopsies are often done in response to suspicious mammographic findings, as discussed in the Diagnosis section of this article.
