Three cases of the infrequent mucocutaneous Leishmaniasis, with nasal involvement in two of them and affection of the hypophrarynx and larynx in the other one are presented. We remark, in the case with laryngeal disease, that it was the onset of an AIDS in a patient unknown to be HIV+. Leishmaniasis of the larynx has not been described before as the onset of an AIDS. Symptomatology, evolution and treatment of this disease are revised, pointing out the increasing association, in our country, between leishmaniasis and AIDS, and considering the possibility of including the leishmania infection as an AIDS criteria in HIV+ patients, and to rule out an IVH infection in a patient with an atypical leishmaniasis either for the site involved or the evolutive course of the disease.

Bilateral choanal atresia in newborns is a life-threatening malformation. The urgency management includes, first of all, the establishment of a sure orotracheal airway and a delayed surgical correction. A few instances do not produce an acute respiratory distress in newborns and failed to be diagnosed until nasal obstruction develops other symptoms in adult life.
