Measles rash. I. Light and electron microscopic study of skin eruptions. 1975

A Kimura, and K Tosaka, and T Nakao

Measles skin lesions were studied by light and electron microscopy. In the epidermis multinucleated giant cells were observed just beneath the hypertrophic horney layer at the maximum stage of rash; they were believed to result by an abnormal process of hyper- or parakeratosis. Neither typical inclusions nor viral nucleocapsids could be detected in any part of the epidermal layer. Most characteristical changes were dermal edema and spongiosis with mononuclear cell infiltration as well as the detection of measle virus-like microtubular structures (nucleocapsids) in the endothelium of dermal capillaries. Is is assumed that measles exanthema is a manifestation of an Arthus reaction elicited by viral antigen in the endothelium of dermal capillaries.

UI	MeSH Term	Description	Entries
D007181	Inclusion Bodies, Viral	An area showing altered staining behavior in the nucleus or cytoplasm of a virus-infected cell. Some inclusion bodies represent "virus factories" in which viral nucleic acid or protein is being synthesized; others are merely artifacts of fixation and staining. One example, Negri bodies, are found in the cytoplasm or processes of nerve cells in animals that have died from rabies.

D007223	Infant	A child between 1 and 23 months of age.	Infants
D008297	Male		Males
D008457	Measles	A highly contagious infectious disease caused by MORBILLIVIRUS, common among children but also seen in the nonimmune of any age, in which the virus enters the respiratory tract via droplet nuclei and multiplies in the epithelial cells, spreading throughout the MONONUCLEAR PHAGOCYTE SYSTEM.	Rubeola
D008459	Measles virus	The type species of MORBILLIVIRUS and the cause of the highly infectious human disease MEASLES, which affects mostly children.	Edmonston virus
D008854	Microscopy, Electron	Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.	Electron Microscopy
D008870	Microtubules	Slender, cylindrical filaments found in the cytoskeleton of plant and animal cells. They are composed of the protein TUBULIN and are influenced by TUBULIN MODULATORS.	Microtubule
D002196	Capillaries	The minute vessels that connect arterioles and venules.	Capillary Beds,Sinusoidal Beds,Sinusoids,Bed, Sinusoidal,Beds, Sinusoidal,Capillary,Capillary Bed,Sinusoid,Sinusoidal Bed
