Concurrent Presence of Sjogren’s Syndrome, Warthin Tumor, and MALT Lymphoma in a Parotid Gland and Hashimoto’s Thyroiditis

초록

A 54-year-old female patient was referred due to a mass in the left salivary gland. A neck CT was performed and surgery was agreed due to a suspected Warthin tumor. The patient was also diagnosed with Sjogren's syndrome and Hashimoto’s thyroiditis and treated. Warthin tumor and extranodal marginal zone B-cell lymphoma were also diagnosed after parotidectomy. The coexistence of the two autoimmune diseases, Hashimoto’s thyroiditis and Sjogren's syndrome, has been reported, as has the coexistence of Warthin tumor and malignant tumor within a single salivary gland. However, these four diseases have not previously been reported in an individual patient. The authors treated a patient who was first diagnosed with Sjogren's syndrome and Hashimoto’s thyroiditis, and subsequently also with Warthin tumor and extranodal marginal zone B-cell lymphoma after superficial parotidectomy. Therefore, this case is reported together with a related literature review.
