We report a benign encapsulated thymoma in an 11-year-old boy. Histologically, it showed foci of medullary differentiation mimicking the normal corticomedullary thymic architecture. We emphasize the rarity of thymomas in children and the possibility of mistaking this uncommon pattern of thymoma for other mediastinal tumors.
