HISTORY AND ADMISSION FINDINGS: A 29-year-old hemophiliac with HIV infection for which he was receiving antiretroviral treatment (ART) with indinavir, zidovudine and zalcitabine reported increasing swelling of the neck. Physical examination noted a soft to doughy swelling, not sensitive to pressure, extending from the neck to between the shoulder blades.
INVESTIGATIONS: Ultrasonography and magnetic resonance imaging revealed the swelling to consist of an accumulation of subcutaneous fat without capsule. Cytology demonstrated benign fatty tissue. Blood triglycerides totalled 667 mg/dl.
DIAGNOSIS, TREATMENT AND COURSE: The typical location, absence of a capsule and the cytological finding confirmed the clinical diagnosis of drug-induced benign symmetrical lipomatosis (BSL, also called peripheral lipodystrophy) in ART. A connection with the hyperlipoproteinaemia is supported by the observation that the patient used to have a normal fat metabolism; the onset of BSL coincided with a massive increase in triglyceride levels. The hyperglyceridaemia and clinical signs improved on a low-fat diet.
CONCLUSIONS: BSL can occur in the course of ART in HIV infection, when reverse-transcriptase inhibitors or protease inhibitors are being taken. Medication should not be changed, when antiretroviral treatment is adequate. To reduce the symptoms low-fat diet should be tried, as well as administration of HMG-CoA-reductase inhibitors or, if necessary, surgical liposuction.
