Abstract

Toxoplasma lymphadenitis is the most common clinical manifestation of toxoplasmosis in an immunocompetent host. In foreign countries, it is a relatively common etiology of reactive hyperplasia of lymph nodes, but it is still rare in Korea. The cervical lymph nodes are the most commonly involved, whereas systemic manifestations are rare. We are reporting a case of toxoplasma lymphadenitis in an immunocompetent host. A 31-year-old man was admitted to the hospital because of submandibular lymph node enlargement for 3 months. Toxoplasma lymphadenitis was diagnosed by positive IgG and IgM toxoplasma antibody titer and specific pathologic findings of submandibular lymph node, such as reactive follicular hyperplasia, epitheioid histiocytes in the interfollicular area, and infiltrations of subcapsular monocytoid B lymphocytes. In Korea, travels to and from other countries and contacts with foreigners are increasing, possibly increasing the incidence of toxoplasma lymphadenitis, which should be considered in the differential diagnosis of lymphadenitis.
