[HIV-associated Penicillium marneffei infection].

We report on an HIV positive patient with a disseminated Penicillium marneffei infection. A 35-year-old Swiss homosexual male with HIV-associated immunodeficiency with a CD4 cell count of 90/mm3 presented with a two-month history of malaise, intermittent fever, loss of weight, unproductive cough and widespread molluscum contagiosum-like skin lesions, mainly on the face. The patient had travelled extensively and had last visited Thailand 19 months before admission. The chest X-ray showed bilateral diffuse reticulonodular markings. The diagnosis was suspected in bronchoalveolar lavage, which showed round-to-oval intracellular yeast cells but also elongated sausage-shaped extracellular forms. The diagnosis was confirmed on culture. Penicillium marneffei was further isolated from the following specimens: blood cultures, bone marrow, stool, skin and tracheal mucosa biopsy. Intravenous amphotericin B therapy led to a complete subsidence of all symptoms and the skin lesions healed without leaving a scar. The infection, with its clinical presentation, epidemiology, diagnostic problems and therapy is reviewed. We stress that since Penicillium marneffei is an increasingly important pathogen in HIV positive patients in Southeast Asia, this fungus can also be imported to Europe by travellers. If immunocompromised patients have molluscum contagiosum-like skin lesions, pneumonitis and a history of travelling in Southeast Asia, disseminated Penicillium marneffei infection should be considered in differential diagnosis.
