Oral Manifestations in the American Tegumentary Leishmaniasis
INTRODUCTION American tegumentary leishmaniasis (ATL) can affect the skin or mucosa (mucocutaneous leishmaniasis - MCL) including the oral cavity. MCL oral lesions are often confused with other oral diseases, delaying diagnosis and specific treatment, and increasing the likelihood of sequelae. Thus, increasing the knowledge of the evolution of ATL oral lesions can facilitate its early diagnosis...
متن کاملTegumentary leishmaniasis and coinfections other than HIV

TL patients may concurrently carry other pathogens, which may influence the clinical outcome of TL. METHODOLOGY AND PRINCIPAL FINDINGS This review focuses on the frequency of TL coinfections in human populations, interactions between Leishmania and other pathogens in animal mo...
متن کاملPeriungual tegumentary leishmaniasis: a diagnostic challenge*
Periungual and paronychia-like skin lesions can mimic various diseases, setting up a diagnostic challenge that invariably requires correlation with complementary tests. We report a case of an ulcerated tumor of the nailfold diagnosed as leishmaniasis. Although paronychia-like cutaneous leishmaniasis is a rare variant, its epidemiological relevance in Brazil should prompt dermatologists to inclu...
متن کاملAmerican tegumentary leishmaniasis: Langerhans cells in Montenegro skin test.
This work analyzed the histopathology and epidermal Langerhans cells (LC) of Montenegro skin test (MST) in patients with American tegumentary leishmaniasis (ATL) in order to in situ characterize and compare the immunological reaction of the two major clinical forms of ATL, localized cutaneous leishmaniasis (LCL) and mucocutaneous leishmaniasis (MCL). MST histopathology of both LCL and MCL showe...
متن کاملTumor Necrosis Factor-α in Human American Tegumentary Leishmaniasis
Tumor necrosis factor-alpha (TNF-α) is a cytokine produced by activated macrophages and other cells. In order to verify whether the serum levels of TNF-α in American tegumentary leishmaniasis patients are associated with the process of cure or aggravation of the disease, 41 patients were studied: 26 cases of cutaneous leishmaniasis (CL) and 15 of mucocutaneous leishmaniasis (MCL). During active...
