The tortoiseshell pattern in one or both sides of the submandibular glands in mucosa-associated lymphoid tissue lymphoma is related to chromosomal aberrations and the disease extent.

Objective: Lesions of mucosa-associated lymphoid tissue (MALT) lymphoma in the submandibular glands are localized or a part of systemic involvement in association with chromosomal aberrations. This series was undertaken to investigate the sonographic features of MALT lymphoma in the submandibular glands and their relationships with chromosomal aberrations and the disease extent.

Methods: A total of 5 patients with MALT lymphoma without Sjögren syndrome in the submandibular glands were enrolled in this series.

A case of neonatal mature teratoma transformed to malignancy in the neck extending to the mouth floor.

A case with neonatal teratoma originating from the cervicofacial region which transformed to be malignant during treatment is reported. The case is a full-term baby girl with swallowing difficulty and has a mass at the floor of her mouth with the right neck swelling. The mass was revealed to be multi-cystic and extending deep into the sublingual space and protruding outside.

Clinical utility of a rapid test for uristatin.

Objectives: Uristatin is a trypsin inhibitor present in urine that is increased in most patients with bacterial or viral infections and in many with inflammatory disorders. We included the assay of uristatin as part of a screening program carried out by pediatricians on 4207 Japanese schoolchildren to judge the ability of uristatin to identify those with an infection and (or) inflammation of any cause. We used urine dipsticks for the assay of uristatin, creatinine, albumin, blood, leukocyte esterase, and protein.
