Syphilis may affect the pulmonary artery as a productive-cicatricial lesion like that form common in the aorta, the so-called Döhle-Heller type; it may occur as a gummatous arteritis, or it may be manifested simply by the formation of gummas. Warthin further accepted as syphilitic a form of diffuse arteritis which affects principally the smaller vessels.
