Thymomas are rare neoplasms comprising less than 1% of adult cancers. Ectopic thymomas are thought to arise from aberrant thymic tissue displaced during embryologic development and are extremely rare accounting for only upto 4% of all thymomas. Ectopic intrathyroidal thymoma is a rare entity with only eight previous cases reported to the best of our knowledge. Here we present a rare case of ectopic primary intra thyroidal thymoma with the clinical, morphological and immunohistochemical features.
