Two imported cases of Penicillium marneffei infection in Belgium are r
eported. Both patients are Thai women co-infected with HIV. P. marneff
ei infection should be suspected in immunocompromised patients origina
ting or travelling from South-East Asia with unexplained fever (>38 de
grees C), weight loss, a generalised lymphadenopathy, hepatomegaly, sp
lenomegaly, skin lesions, cough and anaemia. Diagnosis is made by cult
ure and/or histopathological examination. Mild to moderate infections
are treated with itraconazole 400 mg/day as first choice. Amphotericin
B parenteral therapy may be required for seriously ill patients. Main
tenance therapy with itraconazole 200 mg/day is necessary to prevent r
elapses.
