Two Very Rare Cases of Metastatic Thymic Carcinoma with Sjogren's Syndrome: A Case Series.

ABSTRACT: Thymic tumours are rare thoracic malignancies with thymic carcinoma accounting for approximately 12% of all thymic tumours compared to thymomas which account for approximately 86%. Unlike thymomas, it is very rare for thymic carcinomas to be associated with autoimmune disorders or paraneoplastic syndromes.

One patient opted for surveillance of their malignancy, whil
