Squamous Cell Carcinoma, right upper cheek; Lesion outlined in blue marker with a dashed line prior to biopsy (Original Post: Shared in Squamous Cell Carcinoma) Squamous Cell Carcinoma, well differentiated, left upper paraspinal back marked for biopsy with adjacent actinic keratosis (Original Post: Shared in Squamous Cell Carcinoma )
Although this epithelium is referred to as squamous, many cells within the layers may not be flattened; this is due to the convention of naming epithelia according to the cell type at the surface. In the deeper layers, the cells may be columnar or cuboidal. [1] There are no intercellular spaces.
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] Light Green SF yellowish confers a blue staining for the cytoplasm of active cells such as columnar cells, parabasal squamous cells, and intermediate squamous cells. [14]
Squamous cell papilloma of the mouth or throat is generally diagnosed in people between the ages of 30 and 50, [1] and is normally found on the inside of the cheek, on the tongue, or inside of lips. Oral papillomas are usually painless, and not treated unless they interfere with eating or are causing pain. [ 1 ]
SGc tumor cells stain positive with epithelial membrane antigen (EMA), cytokeratin -7 (CK-7), Ber-EP4, adipophilin, perilipin, and androgen receptor (AR). [6] [17] [2] Meanwhile, SGc cells are negative for carcinoembryonic antigen (CEA), gross cystic disease fluid protein, and S100 protein, helping differentiate SGc from SCC and BCC.
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.
ThinPrep pap smear with group of normal cervical cells on left and HPV-infected cells showing features typical of koilocytes: enlarged (x2 or x3) nuclei and hyperchromasia. A koilocyte is a squamous epithelial cell that has undergone a number of structural changes, which occur as a result of infection of the cell by human papillomavirus (HPV). [1]
