Positive histologic stains that aid in the diagnosis of conditions of or affecting the human integumentary system Stain Cell, material, and/or structure(s) stained Condition(s) in which stain is positive Actin-specific enolase: Infantile digital fibromatosis: AE1/AE3: Squamous cell carcinoma: Alcian blue: Lipoid proteinosis Papular mucinosis ...
Cell nuclei should be crisp, blue to black on color [12] [13] and the chromatin patterns of the nucleus should be well defined. Cell cytoplasm stains blue-green and keratin stains orange in color. [13] [5] Eosin Y stains the superficial epithelial squamous cells, nucleoli, cilia, and red blood cells. [2]
[2] [6] SGc share a similar histological presentation to other cutaneous tumors, such as sebaceous adenomas, basal cell carcinomas (BCC), squamous cell carcinomas (SCC), and clear cell tumors. [6] [17] A high level of suspicion is extremely important to prevent treatment delay and increased mortality. [17]
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 .
The prognosis varies dramatically, depending on the type and stage at the time of treatment. However, the most common epitheliomas are very easily treated and rarely result in death. [ 2 ] The condition did, however, take the life of Scottish golfer Willie Dunn, Sr. in 1878 at a time when the ailment was likely not fully understood.
neglected squamous cell carcinoma skin of scalp Advanced squamous cell carcinoma, excision specimen. Note invasion subcutaneous tissue. Cutaneous squamous-cell carcinoma (cSCC), also known as squamous-cell carcinoma of the skin or squamous-cell skin cancer, is one of the three principal types of skin cancer, alongside basal-cell carcinoma and melanoma.
The H&E staining procedure is the principal stain in histology [3] [7] [2] [5] in part because it can be done quickly, [7] is not expensive, and stains tissues in such a way that a considerable amount of microscopic anatomy [9] [10] is revealed, [7] [5] [4] and can be used to diagnose a wide range of histopathologic conditions. [8]
Comparison H&E stain (left) with BerEP4 immunohistochemistry staining (right) on a pathological section having basal cell carcinoma (BCC) with squamous cell metaplasia. Only BCC cells are stained with BerEP4 in this image. [27] EpCAM is often overexpressed in certain carcinomas, including in breast cancer, colon cancer and basal cell carcinoma ...
