High-grade serous carcinoma (HGSC) is a type of tumour that arises from the serous epithelial layer in the abdominopelvic cavity and is mainly found in the ovary.HGSCs make up the majority of ovarian cancer cases [1] and have the lowest survival rates. [2]
A retrospective study of patients treated with resection, chemotherapy and autologous hematopoietic stem cell transplantation had a higher 1-year and 5-year overall survival (100%, 33%) compared to one-year survival (73%) and five-year survival (14%) without transplantation; a second retrospective study supported the usefulness of ...
Adenocarcinoma is a malignant epithelial tumor, originating from superficial glandular epithelial cells lining the colon and rectum. It invades the wall, infiltrating the muscularis mucosae layer, the submucosa, and then the muscularis propria. Tumor cells describe irregular tubular structures, harboring pluristratification, multiple lumens ...
Individual cell keratinization; Loss or reduction of cellular cohesion; Cellular pleomorphism; Loss of basal cell polarity; Koilocytosis; Epithelial cell dysplasia is divided into three categories of severity: mild, moderate, and severe. Epithelial dysplasia becomes microinvasive squamous cell carcinoma once the tumor begins to invade nearby ...
Epithelial polarity is one example of the cell polarity that is a fundamental feature of many types of cells. Epithelial cells feature distinct 'apical', 'lateral' and 'basal' plasma membrane domains. Epithelial cells connect to one another via their lateral membranes to form epithelial sheets that line cavities and surfaces throughout the ...
Normal (left) versus dysplastic (large at right) colonic crypts, the latter conferring a diagnosis of a tubular and/or villous adenoma. Histopathology of high-grade dysplasia in a tubulovillous adenoma, in this case seen mainly as loss of cell polarity, as cells become more plump and haphazard than the elongated and parallel nuclei of ...
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.
The condition is a laboratory diagnosis and refers to unusual cells in the lobules of the breast. [1] The lobules and acini of the terminal duct-lobular unit (TDLU), the basic functional unit of the breast, may become distorted and undergo expansion due to the abnormal proliferation of cells comprising the structure.
