[Skin changes in HIV infections]

The spectrum of dermatologic findings related to human immunodeficiency virus includes a variety of cutaneous and mucocutaneous disorders. The most frequent diagnoses are oral candidiasis, seborrheic dermatitis, pyodermas and Kaposi's sarcoma. Distinctive skin lesions occur at various stages of HIV infection. Especially herpes zoster, seborrheic dermatitis and oral candidiasis may act as indicators, and their recognition is of particular importance for the early diagnosis of HIV infection and for the prevention of further opportunistic infections. In addition, some dermatologic findings as mollusca contagiosa and Kaposi's sarcoma occur mostly as late manifestations and may constitute a cutaneous correlate of advanced cellular immune deficiency.
