Direct immunofluorescence in the diagnosis of toxoplasmic lymphadenitis

The diagnosis of toxoplasmic lymphadenitis was established through the demonstration, by direct immunofluorescence, of toxoplasma cysts and trophozoites in a cervical lymph node biopsy which also had a characteristic histopathology. The patient had cervical lymphadenopathy and increased specific fluorescent antitoxoplasma IgG and IgM antibodies.
