Melioidosis, the great mimicker: a report of 10 cases from Malaysia.

Between 1981 and 1986, 10 consecutive cases of melioidosis were seen at the University Hospital, Kuala Lumpur, Malaysia. They illustrate the amazing guises of melioidosis presenting as: abscesses of the supraspinatus muscle, psoas muscle, brain and liver; three different pulmonary forms; an acute suppurative dermal lesion; an acute septicaemia; and chronic lymphadenitis. The majority had underlying diseases: diabetes mellitus, the commonest, was present in six, out of whom three had previous pulmonary tuberculosis; other predisposing conditions were renal failure, corticosteroid therapy and malnutrition. Three patients who died had pre-existing renal impairment and developed renal failure later, suggesting that the former is a bad prognostic sign. Clinical diagnosis was difficult: all cases were diagnosed bacteriologically. A high level of clinical awareness is necessary, especially when presentation simulates pulmonary or extrapulmonary tuberculosis in patients with diabetes or other compromised states.
