A 76-year-old female was referred to our hospital because of an anterior mediastinal tumor identified by chest computed tomography (CT). Chest CT and MRI showed a mass shadow in the anterior mediastinum. The serum interleukin-2 receptor level was high, at 1,830 U/mL. We suspected that the tumor was a thymic lymphoma or thymoma. We attempted a thoracoscopic biopsy, but there was severe adhesion. So, we converted to tumor excision via a median sternotomy. The tumor was completely resected. Regarding pathological findings, the tumor was a thymic MALT lymphoma. Thymic MALT lymphoma is rare, so we reviewed surgical cases of thymic MALT lymphoma in the literature.
