Of all the investigative challenges, PEH, a reactive epithelial proliferation is seen secondary to lesions with infectious, inflammatory, reactive, and degenerative origin Pseudoepitheliomatous hyperplasia, abbreviated PEH, is a benign reactive change of squamous mucosa that can mimic squamous cell carcinoma Pseudoepitheliomatous hyperplasia can arise either from the epidermis or from adnexal epithelium, and is almost always associated with persistent inflammation of the subjacent dermis due to a chronic wound, ulcer, infection, malignancy, retained foreign material or an inflammatory dermatitis. It can closely mimic, abut, or degenerate into a squamous cell carcinoma

BACKGROUND Pseudoepitheliomatous hyperplasia (PEH) is a reactive epithelial proliferation occurring secondary to infection, neoplasm, injury, and inflammation. The histopathological characteristics of PEH may lead to it being confused with well-differentiated squamous cell carcinoma (SCC) complicate burn wounds. Pseudoepitheliomatous hyperplasia (PH) is a histologic reaction secondary to a wide range of stimuli, including fungal infection. We describe a case of an 18-year-old man, status-post burns over 70% of his total body surface area, with cutaneous aspergillosis of the axilla and secondary PH. Pseudoepitheliomatous hyperplasia, also called pseudocarcinomatous hyperplasia because of its resemblance to well-differentiated squamous cell carcinoma, is a reactive epithelial proliferation that is characterized by prominent irregular hyperplasia of the epithelium with tongue-like epithelial projections into the dermis

Pseudoepitheliomatous keratotic and micaceous balanitis

Pseudoepitheliomatous hyperplasia (PEH) is a morphologic pattern of reactive squamous epithelial proliferation that occurs in response to underlying infections, inflammations, or neoplasms (Kune 2012; Noffsinger 2007).It is characterized by parallel, elongated, and occasionally irregular columns of highly reactive squamous cells, with prominent nucleoli and abundant mitoses that may extend. Hyperplasia of epidermal squamous cells develops in the surface epithelium, occasionally extending into the hair follicle infundibulum and sebaceous gland ducts. Histologically, squamous hyperplasia is characterized by the thickness of all layers (basal, squamous, granular layers) of nucleated cells in the epidermis; the squamous layer is the most evident (Figure 19.15) Pseudoepitheliomatous hyperplasia of the epidermis occurring with Mycobacterium ulcerans skin infection may result in localization of the infected area with discharge of necrotic material, followed by healing leaving a depressed scar. The process represents more than simple re-epithelization of an ulcerated skin surface; it is a mechanism which produces active extrusion of necrotic material. Pseudoepitheliomatous hyperplasia (PEH), a neglected entity by oral pathologist possesses utmost importance in the field of research. Of all the investigative challenges, PEH, a reactive epithelial proliferation is seen secondary to lesions with infectious, inflammatory, reactive, and degenerative origin. Small sized samples, incomplete excision, improper orientation, and dense inflammatory.

Pseudoepitheliomatous hyperplasia of the skin and soft tissue is an exceedingly puzzling condition, both from the viewpoint of clinical medicine and from that of basic science. In advanced cases, it is almost impossible for the pathologist to make the differential diagnosis between pseudoepithelioma and squamous-cell carcinoma. The final disposition depends upon clinical observation and. Results. p53 expression was observed in all of the six cases of pseudoepitheliomatous hyperplasia, 78.8% of keratoacanthoma, and 75.5% of squamous cell carcinoma. The staining pattern of pseudoepitheliomatous hyperplasia and keratoacanthoma was generally less intense and extensive compared with that of squamous cell carcinoma fficult to distinguish from squamous cell carcinoma (SCC). Further biopsies showed similar nests originating from every hair follicle. We postulated a diagnosis of multifocal pseudoepitheliomatous hyperplasia (PEH) to explain this phenomenon. Because we could find no reference to PEH in the setting of LS, we reviewed the biopsies of 92 women with extragenital and vulvar LS with and without.

Purpose . Pseudoepitheliomatous hyperplasia at the limbus can mimic an ocular surface squamous neoplasia. It is an uncommon manifestation of vernal keratoconjunctivitis and has been reported previously in limbal VKC. It, however, has not been reported as a manifestation in the palpebral form of the disease and needs to be kept in the differential diagnosis of a limbal mass lesion in vernal.
