title: Mucocutaneous manifestations in 22 consecutive cases of primary HIV-1 infection.
abstract: Twenty-two consecutive patients presenting with symptomatic human immunodeficiency virus 1 (HIV-1) seroconversion were studied. Most of the patients had a glandular fever-like illness. All patients had fever and pharyngitis, and eight of them also suffered from ulcers of the oral, genital or anal mucosa. Uniform skin eruptions were observed in 17 of the 22 patients. The exanthem consisted of varying numbers of macular or maculopapular lesions that were oval or rounded in shape, ranging from a few millimetres to 1 cm in diameter. The lesions were distributed on the upper thorax in all cases, and were particularly profuse in the collar region. The face, forehead and scalp were involved in most cases, but the eruption was sparse or absent at the periphery of the extremities. In the majority of patients, the exanthem appeared after 2 or 3 days of fever. The exanthem developed during the first day, persisted for 5-8 days, and then cleared concurrently with the general recovery of the patients. Histopathological studies of skin punch biopsy specimens from four patients showed a sparse lymphocytic cell infiltrate distributed around vessels of the dermal superficial plexus. The infiltrates predominantly consisted of equally represented T-helper/inducer and T-suppressor/cytotoxic cells. A vacuolar aberration of basal layer cells was found in two of the four cases studied histologically. The microscopic findings correspond to the histopathological patterns seen in toxicodermia and in the interface dermatitis of morbilliform viral exanthems. The exanthem is a frequent and characteristic sign of primary HIV infection, which is further indicated if mucosal ulcers are present.
