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.
