The objective was to determine if the pathological subtypes of thymoma were associated with post-thymectomy outcomes of myasthenia gravis (MG), in patients with TAMG. Classification of thymoma is one of the most elusive in pathology, based on one hand on the reduced number of cases and on the difficulty to interpret histological findings on the other.

Type B1 Thymoma vs Type AB Thymoma Rare examples of type AB thymoma may show medullary foci in the lymphocyte-rich areas with TdT+ cells. However, type AB thymomas will always show (at least focally) spindled tumor cells, a greater proportion of keratin-positive tumor cells, and epithelial expression of CD20 in about 50% of cases.
