180Lobomycosis is a chronic dermal infection that presents a wide spectrum of clinicaldermatological manifestations, mainly characterized by the development of keloid lesions as well as nodular, verrucoid and sometimes ulcerous forms. The etiological agent at an international level, according to the consensus nomenclature, has been called Loboa loboi , even though recently it has been accommodated as Lacazia loboi . The present review extensively covers the clinical-epidemiological aspects as well as the most outstanding historical aspects, including the Venezuelan experience and the presentation of two new cases, which substantiate the Amazon basin as an endemic area for the disease.
Leishmaniasis is a diverse group of vector-borne diseases caused by a subset of predominantly intracellular protozoal species of the genus Leishmania. Cutaneous disease may be subdivided into localized, intermediate, and diffuse forms. Intermediate cutaneous leishmaniasis is distributed widely in Latin America and is characterized by cutaneous lesions, which may be accompanied by mucosal disease and demonstrate a tendency toward chronicity and relapse as well as resistance to standard treatment regimens. Leishmania parasites of the subgenus Viannia have been identified as the major etiologic agent of this subset of infections. The present review provides a brief perspective on leishmaniasis followed by a review of classification, transmission, clinical presentation, and evolution of disease, immunology, and current treatment approaches for the intermediate/borderline disseminated subset of cutaneous leishmaniasis.
American cutaneous leishmaniasis is an important endemic zoonotic disease in the New World that comprises a spectrum of clinical manifestations. Diffuse cutaneous leishmaniasis (DCL) is a rare form of the disease characterized by antigen-specific immunodeficiency that often presents with multiple disfiguring non-ulcerated confluent nodules or plaques that involve large areas of the skin, resembling lepromatous leprosy. Relapse is invariable in advanced stages, despite aggressive chemotherapy, and a plethora of drugs has been tested with unchanging results. We report on a severe an exceptional case that resolved after treatment with amphotericin B, a drug considered only mildly effective, and discuss the therapeutic approach to this disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
