A case of toxoplasmosis involving the submental lymphonode of a ten-year-old girl treated with trimethoprim/sulfamethoxazole (TMP/SMZ) is reported. She attended our hospital complaining of painless swelling in the submental area. No apparent inflammatory reaction was found clinically, and the routine laboratory findings were normal. Diagnosis of toxoplasmosis of a lymphonode was made, depending on the serum antibody titer against toxoplasma (LA test; 1: 128) . After 64 days' administration of TMP/SMZ, the antibody titer decreased to 1 : 32 and the swelling of the lymphonode diminished. During the course of the treatment, no side-effects were observed.
