Rupioid histoplasmosis: first case reported in an AIDS patient in Argentina.

Disseminated histoplasmosis is a relatively common AIDS-defining illness, occurring in almost 4% of patients living in endemic areas and it may be the first clinical expression of the HIV infection. A broad spectrum of clinical skin lesions associated with Histoplasma capsulatum infection have been described in AIDS patients, such as erythematous macules, papules, nodules, and pustules. Herpetic, acneiform, erythema multiforme-like, molluscum contagiosum-like, vasculitic, and exfoliative forms have also been reported. To our knowledge, this is the first case of disseminated histoplasmosis in an AIDS patient presented as a rupioid eruption.
