title: An intrapulmonary teratoma associated with thymic tissue.
abstract: A benign teratoma was removed by segmental resection from the upper lobe of the right lung in a girl aged 19 years. This is the twentieth case report of a teratoma occurring in the lung substance and is of special interest because of the identification of thymic tissue histologically. The significance of this in relation to the pathogenesis of intrathoracic teratoma is discussed.
