title: Acquired toxoplasmic lymphadenitis with demonstration of the cyst form.
abstract: Acquired toxoplasmosis usually is diagnosed serologically. Specific histologic criteria allow for the recognition of this disease in lymph node sections. However, Toxoplasma cysts are rarely seen in nodes. The lymph node from a 15-year-old male with asymptomatic lymphadenopathy was found to have typical histologic features of toxoplasmic lymphadenitis. Toxoplasma cysts were identified and specific serology was confirmatory.
