title: Swollen keratinocytes: a histologic marker of unusual human papillomavirus-type infection and immunosuppression.
abstract: Cutaneous papillomavirus infection is common in patients who are immunosuppressed. We describe swollen keratinocytes in the granular layer in lesions from four patients who had human immunodeficiency virus infection. These cells were similar to those described in skin lesions of epidermodysplasia verruciformis. Amplification of DNA from the lesions revealed an amplimer for human papillomavirus using a consensus primer for a highly conserved region of the L1 open reading frame; however, specific binding was not noted when radiolabelled probes for human papillomavirus types 6, 11, 16, 18, and 33 were used. We conclude that the presence of these distinctive swollen cells strongly suggests immunosuppression and quite possibly infection by a less common papillomavirus type.
