Penicillium marneffei is a dimorphic fungus, endemic in South-east Asia. The fungus causes severe disease in immunocompromised patients such as AIDS. However, no case of immune restoration disease of Penicillium marneffei is reported in literature from a non-endemic area.Case PresentationWe report the first case of Penicillium marneffei and Cytomegalovirus infection manifesting as a result of immune restoration one month after initiating HAART. This severely immunocompromised patient had presented with multiple lymphadenopathy, massive hepatosplenomegaly, visual impairment and mild icterus, but no skin lesions. Penicillium marneffei was isolated from lymph node fine-needle aspirates and blood cultures.
In order to diagnose such rare cases, the clinicians, histopathologists and microbiologists alike need to maintain a strong index of suspicion for making initial diagnosis as well as for suspecting immune reconstitution syndrome (IRS) with Penicillium marneffei.
