RESUMO
The visceral form of leishmaniasis caused by Leishmania infantum is frequently observed in Mediterranean countries, however otorhinolaryngeal involvement has only rarely been reported in the literature. We report here the case of a 23-year-old Cameroon man, resident in France since 1991, and presenting with recurrent epistaxis and an epiglottis tumoral lesion. The visceral form of leishmaniasis with hepatosplenomegaly and pancytopenia was diagnosed. Culture of the epiglottal lesion revealed L. infantum. Serological test for human immunodeficiency virus was negative and the patient was not on immunosuppressive drugs. Dramatic improvement was observed with antimony.

During one year, 597 cattle were examined for Mammomonogamus laryngeus infections in the abattoir of Cagayan de Oro, Philippines. The overall prevalence was 23% with no obvious seasonal variations. The infection rate was 19% in animals up to 4 years old and 24% in animals 4-12 years old. In infected animals up to 8 years old an average of eight parasite pairs was found; infected animals of 8-12 years old had 5.2 parasite pairs on average. All worms were located on the posterior side of the epiglottis. Field observations on cattle in Mindanao revealed that adult M. laryngeus had developed on the epiglottis of a tracer calf that had been on pasture for 30 days and then kept away from possible nematode infection for 28 days.

During one year 1249 male cattle were examined for Mammomonogamus laryngeus infections in the slaughterhouse at Kandy, Sri Lanka. The overall prevalence was 40% with only light monthly variations (34 to 52%). The infection rate was highest (47%) in 2 to 2.5 year old animals. In infected animals an average of 6.4 parasite pairs was found with higher numbers in older animals. The majority of worms were located on the posterior side of the epiglottis. Lesions observed were mucosal plugs at the site where the parasites were attached to the mucosa and moderate to severe erosions and ulcers in other zones.
