fibroepithelioma

fibroepithelioma

 [fi″bro-ep″ĭ-the″le-o´mah]
a tumor composed of both fibrous and epithelial elements.

fi·bro·ep·i·the·li·o·ma

(fī'brō-ep'i-thē-lē-ō'mă),
A skin tumor composed of fibrous tissue intersected by thin anastomosing bands of basal cells of the epidermis, enclosing keratin cysts; may give rise to basal cell carcinoma of the nodular type.
Synonym(s): Pinkus tumor

Pinkus tumour

A red-pink polypoid variant of basal cell carcinoma which, in contrast to conventional basal cell carcinomas, is more commonly located on the trunk, back, and extremities.

In general, it can be classified into nodular, pigmented, superficial, infiltrative, sclerosing, and fibroepithelioma of Pinkus (FEP).[1] However, an unusual polypoid type can be present.

BCCs can be classified into several different types based on their morphologies as follows: nodular BCC, cystic BCC, infundibulocystic BCC, morpheaform/cicatricial BCC, infiltrative BCC, micronodular BCC, superficial BCC, pigmented BCC, rodent's ulcer, fibroepithelioma of Pinkus, polypoid BCC, pore-like BCC, aberrant BCC, and solitary BCC.
An additional variant, the fibroepithelioma of Pinkus, typically presents as a solitary nodule on the trunk.
Fibroepithelioma of Pinkus is a true basal cell carcinoma developing in association with a newly identified tumour-specific type of epidermal hyperplasia.
CD-34 and Ki-67 staining patterns of basaloid follicular hamartoma are different from those in fibroepithelioma of Pinkus and other variants of basal cell carcinoma.
(5) BCC has several types due to clinical and histopathological characteristics as nodular, superficial, micronodular, morphemic form, infiltrating, pigmented, metatypic and fibroepithelioma of pinkus.
Fibroepithelioma of Pinkus (FEP) was first described by Hermann Pinkus in 1953 as "premalignant fibroepithelial tumor of the skin'.' In the original article, Pinkus concluded that "these tumors do not constitute a truly new entity, but, rather, that they are an unusual variety of basal-cell epithelioma" [1].
Cystic changes in classical fibroepithelioma of Pinkus
"Fibroepithelioma of pinkus" most commonly occurs on the lower back.
The main clinical BCC subtypes are nodular, micronodular, superficial, infiltrative (including morpheaform/sclerotic BCC), and fibroepithelioma of Pinkus.
The histological variants are Nodular basal cell carcinoma, Basal cell carcinoma, solid type with cystic degeneration, Infiltrative basal cell carcinoma, Adenoid basal cell carcinoma, Micronodular basal cell carcinoma, Pigmented basal cell carcinoma, Keratotic basal cell carcinoma, Basal cell carcinoma with sebaceous differentiation and Fibroepithelioma of Pinkus (fibroepithelial basal cell carcinoma).
