[Vascular lesions in mucosal leishmaniasis]

In 20 our of 52 cases of mucosal- leshmaniasis vascular lesions of the exudative type were observed. Arteria and vena were equally involved. These lesions are characterized by oedematous imbibition of the vascular wall, formation of fibrinoid and fibrotic proliferation of the intima. In addition fibrin thrombus and inflammatory vascula lesions were also detected. In the development of vascular lesions authors emphasize the role of immunological processes in which immune-complexes and/or membrane-reactive autoantibodies have an importance.
