A fourteen-year-old boy was examined for painless lymphadenopathy in the submandibular and cervical regions. The patient was treated with incision and antibiotics, without change in the size of the lymphnodes during 3 months. Radiological examination was performed. The findings in computed tomogram and echogram revealed two masses in the left submandibular region. One mass was approximately 2cm, the other mass was 3cm in diameter. In contrasted radiographic findings of the submandibular gland, the masses were applying pressure on the left submandibular gland. The two submandibular lymphnodes were excised with the adhered left submandibular gland for excisional biopsy. Piringer's lymphadenitis or acquired lymphadenitis was suspected histopathologically. However, they were so rare in Japan that reactive follicullar hyperplasia of the left submandibular lym-phnodi were diagnosed. Toxoplasma cysts were identified and specific serology was confirmatory.
