Squamous-cell carcinoma of the skin is generally distinguishable by for example relatively more cytoplasm, horn cyst formation and absence of palisading and cleft formations. Yet, a high prevalence means a relatively high incidence of borderline cases, such as basal-cell carcinoma with squamous cell metaplasia (H&E stain at left in image).
Mast cell: Mastocytosis: Bcl-2: Basal cell carcinoma Primary cutaneous marginal zone lymphoma Diffuse large B-cell lymphoma leg type: Bcl-6: Primary cutaneous follicular lymphoma: BerEp4: Desmoplastic trichoepithelioma Basal cell carcinoma: Brown–Brenn: Eumycotic mycetoma: CAM 5.2: Merkel cell carcinoma: CCR7: Melanoma: Carcinoembryonic ...
Cutaneous squamous-cell carcinoma is the second-most common cancer of the skin (after basal-cell carcinoma, but more common than melanoma). It usually occurs in areas exposed to the sun. Sunlight exposure and immunosuppression are risk factors for SCC of the skin, with chronic sun exposure being the strongest environmental risk factor. [26]
Of nonmelanoma skin cancers, about 80% are basal-cell cancers and 20% squamous-cell skin cancers. [14] Basal-cell and squamous-cell skin cancers rarely result in death. [6] In the United States, they were the cause of less than 0.1% of all cancer deaths. [1] Globally in 2012, melanoma occurred in 232,000 people and resulted in 55,000 deaths. [6]
Squamous-cell carcinoma (SCC), also known as epidermoid carcinoma, comprises a number of different types of cancer that begin in squamous cells. [1] These cells form on the surface of the skin, on the lining of hollow organs in the body, and on the lining of the respiratory and digestive tracts .
But provided with an accurate clinical information, he/she might consider the diagnosis of a well differentiated squamous cell carcinoma or keratoacanthoma. It is not infrequent for two, three or more biopsies to be performed by different doctors for the same skin condition, before the correct diagnosis is made on the final biopsy.
Not all basal-cell cancers originate in the basal cells but they are so named because the cancer cells resemble basal cells when seen under a microscope. [ 4 ] In a growing fetus, fingerprints form where the cells of the stratum basale meet the papillae of the underlying papillary layer of the dermis , resulting in the formation of the ridges ...
BerEp4 is normally negative in squamous epithelium and mesothelium, but otherwise normally positive most epithelial cells of the body. [3] It can also help in distinguishing pulmonary adenocarcinoma (positive BerEp4) from mesothelioma (generally negative BerEp4).
