Acute glandular fever-like illness in a patient with HTLV-III antibody

A lymph node biopsy obtained from a patient with human T-cell lymphocytotropic virus III/lymphadenopathy-associated virus (HTLV-III/LAV) antibody, presenting with an acute glandular fever-like illness, was examined by electron microscopy. Numerous pathological changes were present in the biopsy, including hypertrophy of smooth endoplasmic reticulum, intracytoplasmic rod-like inclusions within the cisternae of endoplasmic reticulum, multivesicular bodies, test-tube and ring-shaped forms, and tubulo-reticular structures. Intranuclear and intracytoplasmic viral-like particles measuring 105-120 nm in diameter and small cytoplasmic particles measuring 50-70 nm in diameter were found in some degenerating lymph node cells. These pathological findings may reflect a host cell response to various pathological and viral stimuli resulting from immune deficiency owing to infection with HTLV-III/LAV.
