Abstract
It affects the upper part of the aerodigestive tract, with mainly lesions in the oral and nasal mucosa and occasionally in the larynx and pharynx. The exclusive involvement of oral mucosa is quite rare.
The diagnosis of leishmaniasis is a real challenge for all professional team.
In Brazil, the highest incidence of Leishmaniasis is in the Northern Region, which comprises the States of Acre, Amapá, Amazonas, Pará, Rondônia, Roraima and Tocantins.
Coexistence of parasitic diseases between Paracoccidioidomycosis and Leishmaniasis.
Introduction
Leishmaniasis Mucosa (LM) is a tropical disease that affects the upper respiratory tract and/or oral mucosa. Its etiological agent is Leishmania spp. Paracoccidioidomycosis disease caused by the fungus Paracoccidioides brazilienses. The aim is to report a case of Leishmaniasis Mucosa in association with Paracoccidioidomycosis.
Presentation of case
A male patient, 24 years old; Intraorally, presence of a non-bleeding erythro-leucoplastic lesion that affected the soft palate and oropharynx; 3 years of evolution. On the face Computerized Tomography (CT) examination, it was possible to observe muco-periosteal thickening in the soft palate region; immunohistochemical markings for Paracoccidiodes brasiliensis. He was diagnosed with Leishmaniasis by Montenegro intradermoreaction (MIDR).
Discussion
The predisposition to Paracocodioidomycosis after Leishmaniasis infection is justified by factors already elucidated – hygiene, nutrition habits and immunodeficiency, but the reason for the non-progression of the fungus after years of evolution could be related to its inhibition due to the presence of the protozoan in the same wound.
Conclusion
This phenomenon may be explained by future studies that need to be performed to answer such questions.
