Ghost cells: A journey in the dark…

چکیده
Ghost cells have been a topic of controversy since a long time. The appearance of these cells in different lesions has given it varying terms. In lesions like that of Calcifying cystic odontogenic tumor (CCOT), these cells have been termed as 'Ghost cells' whereas similar descriptive cells have been called shadow/translucent cells in non-odontogenic lesions like Craniopharyngiomas of the pituitary gland and Pilomatricomas of skin. Controversy arises because of the fact that there are varying opinions and incomplete knowledge about their origin, nature, significance and relation in different neoplasms. Irrespective of the origin, these cells are seen in odontogenic and non-odontogenic neoplasms, which probably direct us towards a missing link between these differing neoplasms. This article attempts to present a review on the concepts around these peculiar cells and shed some light on these ghosts that are still in dark.

متن کاملDemocracy – The Real ‘Ghost’ in the Machine of Global Health Policy; Comment on “A Ghost in the Machine? Politics in Global Health Policy”
Politics is not the ghost in the machine of global health policy. Conceptually, it makes little sense to argue otherwise, while history is replete with examples of individuals and movements engaging politically in global health policy. Were one looking for ghosts, a more likely candidate would be democracy, which is currently under attack by a new global health technocracy. Civil society moveme...
متن کاملGhost Condensation and Gravity in Higgs Phase
A tachyon is considered to be sick in the context of particle mechanics, but in field theory just indicates instability of a background. We consider a similar possibility that a ghost in field theory might be just an indication of instability of a background and that it can condense to form a different background around which there is no ghost. We construct a low energy effective field theory b...
