Facial Demodicidosis Revealing HIV
Journal Title: Journal of Dermatology Research - Year 2022, Vol 3, Issue 1
Abstract
Demodecidosis is an opportunistic cutaneous ectoparasitosis, common to humans and many mammals, caused by the proliferation of Demodex in the pilosebaceous apparatus. This obligate saprophyte of the skin, ostia-pilosebaceous of seborrheic areas, can become pathogenic in case of cosmetic abuse and debilitated terrain or altered immune status [1] . We report a case of facial demodecia revealing an infection by the human immunodeficiency virus. A 34 years old man with a history of multiple sexual relationships, presented with a pruritic maculo- papular rash of the face that had been evolving for 5 months, unimproved by the application of fusidic acid and exacerbated by dermocorticoids. Clinical examination revealed a pruritic and oedematous erythematous patch on both cheekbones, forehead and chin associated with pustular lesions (Fig. 1). Dermoscopic analysis identified whitish filiform structures corresponding to the Demodex parasite attached to the skin (Fig. 2). The histopathological study confirmed the diagnosis (Fig. 3). The blood count showed a lymphopenia of 520/mm3 with normal eosinophils. HIV serology came back positive (CD4 lymphocytes=120/mm3). The patient noted an improvement under oral erythromycin and local ketokonazole with attenuation of the infiltration and disappearance of pruritus.
