AbstractIntroduction: Skin harbours specialized subsets of antigen-presenting dendritic cells, that take up microbial and tissue antigens, migrate to peripheral lymph nodes and present processed antigens to naïve T lymphocytes. The T lymphocytes are thereby induced to become activated and to expand in number, and T cells so activated acquire the capacity to migrate preferentially to skin, directed by specific homing receptors, where they exert their effector functions against relevant antigens .
Methodology: HIV positive patients attending Skin and STD Department and also patients referred from other departments of Hospital were screened for skin diseases by taking detailed history, clinical examination and relevant laboratory investigations. HIV positive patients having skin diseases were included in the study.
Results: Out of 60 patients included in the study 15 patients (25%) had non-infectious dermatoses. Seven patients (11.7%) presented with pruritic papular eruptions, 4 (6.7%) had adverse cutaneous drug reactions, 2 (3.3%) had photodermatitis and only 1 case (1.7 %) of pityriasisrosea was seen.
Conclusion: Photodermatitis was seen in 2 patients (3.3%) included in the study. Only 1 (1.7%) patient had pityriasis – rosea with typical clinical features.
