Cutaneous manifestations of human immunodeficiency virus infection in Taiwan

Cutaneous manifestations are common and often the presenting feature of human immunodeficiency virus (HIV) infection, but a comprehensive study of HIV-associated skin lesions is not available in Taiwan. We reviewed all skin lesions in all HIV patients diagnosed in our department between 1990 and 1998 to document the spectrum of skin manifestations, the frequency of each disorder, and their relationship with CD4 counts. A total of 64 HIV patients were studied, including 38 with acquired immunodeficiency syndrome (AIDS) (CD4 < 200 x 10(6) cells/L) and 26 who had not developed AIDS (non-AIDS). There were 142 episodes of skin conditions representing 25 different skin diseases, including oral candidiasis (15% in non-AIDS vs 71% in AIDS patients), drug eruptions, herpes simplex, seborrheic dermatitis, dermatophytosis, herpes zoster, secondary syphilis, condyloma acuminatum, Kaposi's sarcoma (16% among AIDS patients), hairy leukoplakia, and molluscum contagiosum (13% among AIDS patients), in decreasing order. Several unusual cases are briefly described, including verrucous herpes infection, condyloma-like molluscum contagiosum, and AIDS-associated pigmented erythroderma. In our study, 70% of all HIV patients had skin diseases, with an average of 2.2 conditions per patient (3.2 in AIDS patients vs 0.7 in non-AIDS patients; p < 0.001). A broad spectrum of HIV-associated skin diseases was observed in our series. The frequency of HIV-associated skin disease was 92% in AIDS patients and 39% in non-AIDS patients; 78% of skin lesions in AIDS patients were diagnosed when CD4 counts were below 100 x 10(6) cells/L.
