Toxoplasmic lymphadenitis--a clinicopathological study.

Forty-three cases of toxoplasmic lymphadenitis were studied. They constituted 0.5% of all lymph node biopsies and 4.2% of reactive lymphadenitis. The histological findings supporting a diagnosis of toxoplasmosis were correlated with serological studies. The condition primarily affects young men, causing cervical lymph node enlargement and varying degrees of fatigue, malaise, cough and fever. It is usually self-limited. This study emphasizes the need for clinicians to consider toxoplasmosis in the differential diagnosis of lymphadenopathies.
