Mucosal-associated lymphoid tissue (MALT) lymphoma is rare in the pediatric population, but primary Sjogren syndrome is a well-established risk factor for this malignancy. This report describes 2 cases of MALT lymphoma in children with Sjogren syndrome. A 15-year-old girl developed MALT lymphoma of the parotid gland as the presenting symptom of Sjogren syndrome. In the second case, a 15-year-old boy with known Sjogren syndrome presenting mainly with arthritis was diagnosed with MALT lymphoma, also of the parotid gland. With early diagnosis and treatment, outcomes in pediatric MALT lymphoma are generally encouraging. Pediatric oncology specialists should be aware of the association of MALT lymphoma with Sjogren syndrome and have a high index of suspicion for this malignant complication.
