Disseminated Penicillium marneffei: presenting illness of advanced HIV infection; a clinicopathological review, illustrated by a case report.
BACKGROUND
Until recently Penicillium marneffei rarely caused human disease. It is now a frequently encountered opportunistic mycosis in HIV positive residents of, and travellers to, south-east Asia.


OBJECTIVE
To review aspects of clinical presentation, pathology, treatment, epidemiology and ecology of P. marneffei. To report a case of disseminated P. marneffei occurring in the Northern Territory which illustrates many typical clinical and pathological features of this infection.


METHODS
A Burmese immigrant presented to Royal Darwin Hospital, Australia with a non-specific, subacute, febrile illness and a diffuse papular rash. The etiological agent was Penicillium marneffei, disseminated in association with advanced HIV infection. The typical travel history and umbilicated papular rash were recognized on admission. Fungal stains of skin biopsies and touch smears facilitated rapid diagnosis, and early antifungal therapy resulted in clinical cure.


CONCLUSIONS
Early distinction of penicilliosis from other opportunistic mycoses, tuberculosis, Leishmaniasis, and molluscum contagiosum is critical for effective management. The characteristic histological and mycological properties of P. marneffei are easily recognizable if the diagnosis is considered. In view of geographic proximity, travel and immigration from endemic areas, Australia should expect further imported penicilliosis as illustrated by this case report.
