Penicillium marneffei is endemic in Southeast Asia, the Guangxi province of China, and Hong Kong. Cases of patients infected with P. marneffei have been very rare, but the incidence has increased markedly during the past several years. This increase is exclusively due to infection among patients infected with human immunodeficiency virus (HIV). The patients usually presented with symptoms and signs similar to other patients with late HIV diseases. These included fever (99% of the patients), anaemia (78%), pronounced weight loss (76%), generalised lymphadenopathy (58%) and hepatomegaly (51%). Skin lesions were seen in 71% of our patients. These lesions were most commonly papules with central necrotic umbilication. It was easy to culture P. marneffei from various clinical specimens. Bone marrow culture was the most sensitive (100%), followed by culture of the specimen obtained from skin biopsy (90%) and blood culture (76%). The fungus was sensitive to amphotericin B, itraconazole, and ketoconazole. Our regimen is to give amphotericin B for 2 weeks, followed by itraconazole 400 mg/day orally for the next 10 weeks. After the initial treatment, the patient is given itraconazole 200 mg/day as secondary prophylaxis for life.
