Ghost cells are pale anucleate cells with homogeneous pale eosinophilic cytoplasm with very pale to clear central areas in place of a basophilic nucleus; which are seen in small clusters or large masses. Few odontogenic and nonodontogenic tumors exhibit the presence of these transparent or shadow cells as a typical feature Ghost cells have been a topic of controversy due to various opinions regarding their origin. This video lecture gives a comprehensive review of ghost cells.. Pilomatrixoma, craniopharyngioma, and calcifying cystic odontogenic tumor are the main entities presenting ghost cells as an important histological feature, in spite their quite different clinical presentation; it seems that they share a common pathway in the formation of these cells Ghost cells (polygonal epithelial cells with eosinophilic cytoplasm that have lost their nuclei but maintain a faint outline of cellular and nuclear membrane) Ghost cells may be calcified Atypia with changes such as increased cellularity, pleomorphism, mitosis, necrosis and infiltrative growt Oral surgery, oral medicine, and oral pathology Abstract Eight of forty-three odontomas in this study contained epithelial ghost cells.

Abstract Objective It was proposed that ghost cells (GCs) are formed as a result of metaplasia caused due to reduction in oxygen supply. Hence, identification of GC like features in irritational fibroma and oral submucous fibrosis (OSMF) is carried out where reduction in oxygen supply to the overlying epithelium is expected due to fibrosis and hyalinization in the stroma Ghost Cell odontogenic carcinoma Journal section: Oral Medicine and Pathology Publication Types: Case Report Ghost cell odontogenic carcinoma: A rare case report and review of literature MĂriam Martos-FernĂˇndez 1, Margarita Alberola-Ferranti 2, Juan-Antonio Hueto-Madrid 3, Coro BescĂłs-AtĂn .

Diagnosis. Ghost cell glaucoma is a clinical diagnosis. Diagnostic findings include presence of heme in the vitreous, ghost cells in the anterior chamber, delayed onset of increased intraocular pressure, an open angle on gonioscopy with possible presence of ghost cells layering over the trabecular meshwork inferiorly due to gravity , and often. A ghost cell is an enlarged eosinophilic epithelial cell with eosinophilic cytoplasm but without a nucleus. The ghost cells indicate coagulative necrosis where there is cell death but retainment of cellular architecture. In histologic sections ghost cells are those which appear as shadow cells.

Cancer is defined as the uncontrollable growth of cells that invade and cause damage to surrounding tissue. Oral cancer appears as a growth or sore in the mouth that does not go away. Oral cancer. Columnar cells are tall and skinny, like columns that hold up a porch on a house. In the stomach most of the columnar cells make fluids that mix with food and help digest it. Goblet cells and absorption cells are types of columnar cells that are normally found in the small intestines, but not in the esophagus and stomach
Aim The aim of this study was to characterise plasma cell infiltrates, in terms of IgG4 positivity, in specific and non-specific plasma cell-rich chronic inflammatory conditions of the oral mucosa. Exploring the possibility that specific plasma cell-rich oral inflammatory conditions have association with or represent an oral manifestation of immunoglobulin G4-related disease (IgG4-RD) Oral cancer (also known as mouth cancer or oral cavity cancer) is most often found in the tongue, the lips and the floor of the mouth. It also can begin in the gums, the minor salivary glands, the lining of the lips and cheeks, the roof of the mouth or the area behind the wisdom teeth. The majority of oral cancers arise in the squamous cells. Then a small piece of tissue is removed and sent to an oral pathologist, a specialist who examines the tissue microscopically for evidence of cancer cells. Oral cancer is classified according to the size of the tumor, the location and the number of draining lymph nodes in the neck
