Mucocutaneous leishmaniasis must be included in the differential diagnosis of midline destructive disease: two case reports.

Midline destructive lesions have multiple possible etiologies, which can be grouped into neoplastic, infectious, or vasculitis-associated. The purpose of these case reports and literature review was to highlight the need to include mucocutaneous leishmaniasis in the diagnosis of midfacial lesions in any patient who has lived in Leishmania-endemic areas because this entity meets all of the clinical criteria to be considered a form of midline destructive lesion. We present two cases of mucocutaneous leishmaniasis that occurred in a Bolivian male immigrant and a European male traveler to Panama, in whom lesions were misdiagnosed as different midline destructive lesions with different causes (Wegener, vasculitis, and natural killer or T-cell lymphoma [NKTL]).

[Treatment of Zenker's diverticulum: comparison of different techniques].

Introduction And Objectives: Zenker's diverticulum has been approached surgically with different techniques over the years, evolving from open to endoscopic surgery. The CO(2) laser or the stapler can be used in endoscopic surgery. Our objective was to ascertain the recurrence or persistence of the diverticulum based on the type of surgery performed.
