RESUMO
BACKGROUND: Leishmaniasis is a tropical disease caused by protozoan parasites of the genus Leishmania. Mucosal leishmaniasis has been described as secondary to the cutaneous form; however, isolated mucosal involvement can also occur. Specifically, mucosal leishmaniasis of the lip is poorly described and its diagnosis challenges clinicians. METHODS: We herein report a case of mucosal leishmaniasis affecting the lower lip without cutaneous involvement in a 20-year-old Venezuelan man. The patient had no relevant past medical history. Clinically, a mass-like lesion with ulcerations and crusts was observed. RESULTS: Microscopically, the lesion was composed of granulomatous inflammation along with macrophages containing intracytoplasmic inclusions similar to round-shaped Leishmania. The species Leishmania (Viannia) braziliensis was confirmed. Treatment with meglumine antimonate was effective. The lesion healed satisfactorily, and no side effects or recurrences were observed. CONCLUSION: Clinicians should be aware of isolated forms of mucosal leishmaniasis of the lip, even in cases where the cutaneous lesion is undetected or clinically manifests as self-limiting. Knowing the endemic areas in the scenario of the dynamics of the ecoepidemiology of leishmaniasis is also essential for surveillance and counselling of the population.

INTRODUCTION: The aim of this article is to present a rare case of myiasis caused by Dermatobia hominis. Myiasis is a disease caused by invasion of tissues of animals and humans by larval stages of dipterous (2-winged) flies. There are few reports of oral myiasis in the literature, mostly related to Cochliomyia hominivorax larvae. We present a case of a 53-year-old man with painful swelling of the left lower lip that was confirmed to be myiasis caused by D. hominis. Though more common in tropical and subtropical regions of North and South America, myiasis should be considered in the differential diagnosis of subcutaneous masses among residents or travelers in endemic areas.

Mites collected from the auditory canal of Cebus apella (capuchin monkey), family Cebidae, were identified as Fonsecalges johnjadini (Psoroptidae, Cebalginae). It is the first record of this parasite from this monkey. This paper emphasizes the importance of clinical and anatomopathological examinations for parasitic diagnosis in wild animals.
