Giant cells in measles are called as:
Measles virus infects by invasion of respiratory epithelium. Local multiplication leads to viremia (day 2-3) and subsequently spread to the reticuloendothelial system. Multinucleated giant cells can be demonstrated in both epidermis and oral epithelium by 7-11 days. Two types of giant cells are seen in measles: Wahin Finkeldey cells of reticuloendothelial system and epithelial giant cells of respiratory and other epithelia. Also Know: Measles virus is a spherical, nonsegmented, single-stranded, negative-sense RNA virus and a member of the Morbillivirus genus in the family of Paramyxoviridae. Koplik's spots are pathognomonic of measles and consist of bluish white dots 1 mm in diameter surrounded by erythema. The lesions appear first on the buccal mucosa opposite the lower molars but rapidly increase in number to involve the entire buccal mucosa. Ref: O.P Ghai 6th Ed Page 207;Moss W.J. (2012).
