Munro microabscess L02.9

Pathognomonically significant, abscess-like accumulations of neutrophil leukocytes within parakeratotic corneal layer areas at the border to the stratum spinosum in psoriasis vulgaris. See also microabscesses.

The occurrence of neutrophil granulocytes was first published in Polish in 1895 by Kopytowski from Poland (1900 in a French journal) and only 3 years later by William John Munro.
