1. Comparison of cardiotoxicity between N-methyl-glucamine and miltefosine in the treatment of American cutaneous leishmaniasis
Abstract A 56-year-old male, HIV-positive, presented with a 3-day history of multiple indurated erythematous nodules with superficial and well-defined erosions on his right gluteus. Skin biopsy showed ballooning-necrotic keratinocytes and cultures were positive for herpes simplex 2. Genital herpes simplex infection recurrences may not be restricted to the an

2. Plantar ulcer as an atypical manifestation of cutaneous leishmaniasis
Abstract Cutaneous leishmaniasis is characterized by ulcers with raised edges and a granular bottom, mainly on the lower limbs. This is a case report of a male patient with an ulcer on the left plantar region. The diagnosis was confirmed by positive PCR for L. braziliensis and the presence of amastigotes of Leishmania sp. in the histopathological examination

4. Identification of Leishmania species by high-resolution DNA dissociation in cases of American cutaneous leishmaniasis,
Abstract Background American cutaneous leishmaniasis is an infectious dermatosis caused by protozoa of the genus Leishmania, which comprises a broad spectrum of clinical manifestations depending on the parasite species involved in the infections and the immunogenetic response of the host. The use of techniques for amplification of the parasites DNA based on

6. Molecular diagnosis of cutaneous leishmaniasis in an endemic area of Acre State in the Amazonian Region of Brazil
Abstract INTRODUCTION This study proposes to identify the Leishmania species found in the skin lesions of cutaneous leishmaniasis (CL) patients from Brasiléia municipality (Acre). METHODS Skin biopsy imprints or biopsy fragments were assayed via kDNA-PCR/RFLP and FRET-real-time PCR. RESULTS Of individuals with suspected CL, 18 were positive for Leishm

7. Leishmania (Viannia) braziliensis isolated from the saliva of patients in a cutaneous leishmaniasis-endemic area of northeastern Brazil
Several studies have described the use of non-invasive collection methods, mostly based on the detection of parasite DNA, for diagnosis. However, no Leishmania specimens have been isolated from saliva. Here, we report the first isolation of Leishmania braziliensis from the saliva of humans with cutaneous leishmaniasis but without lesions on their mucosa. The

8. Leprosy and American cutaneous leishmaniasis coinfection
Abstract: Brazil is a country with a high prevalence of infectious diseases such as leprosy and leishmaniasis. However, coinfection of these diseases is still poorly understood. We report a case of a patient who presented with lepromatous leprosy and cutaneous-mucosal leishmaniasis at the same period. After clinical, laboratory, and histopathological diagnos

9. Dermatoscopic signs in cutaneous leishmaniasis
Abstract: Dermoscopy is a non-invasive technique widely used to aid in the characterization and diagnosis of pigmented skin lesions. Recently, it has also been employed for the evaluation of non-pigmented skin tumours, and inflammatory and infectious cutaneous diseases. Although the diagnosis of cutaneous leishmaniasis is confirmed by the demonstration of am

10. Final diagnosis of 86 cases included in differential diagnosis of American tegumentary leishmaniasis in a Brazilian sample: a retrospective cross-sectional study
Abstract: Background: Cutaneous leishmaniasis is distributed worldwide, including Brazil. Its several clinical forms need to be distinguished from other dermatoses. Clinical similarities and lack of a gold standard diagnostic tool make leishmaniasis-like lesions a challenging diagnosis. Objectives. To report the final diagnosis of patients primarily suspec

11. Effect of secondary infection on epithelialisation and total healing of cutaneous leishmaniasis lesions
BACKGROUND Cutaneous leishmaniasis (CL) generally presents with a single or several localised cutaneous ulcers without involvement of mucous membranes. Ulcerated lesions are susceptible to secondary contamination that may slow the healing process. OBJECTIVE This study verified the influence of non-parasitic wound infection on wound closure (epithelialisa
