I read the communication from Hernandez and colleagues1 in the December 2000 issue of the ARCHIVES in which they report a case of disseminated porokeratosis and add to the list of diseases associated with this unusual keratosis. Although textbooks have considered the disease to be a disorder of keratinization or a chromosomal defect,2 I believe that it is clear at this point that porokeratoses are actually manifestations of viral infection.
