Diagnosis
Diagnosis is based on the characteristic appearance of non-healing raised, scaling lesions that may ulcerate and become secondarily infected with organisms such as Staphylococcus aureus, in someone who has returned from an endemic area.In resource limited settings, fine-needle aspiration of the lesion  is confirmatory with identification of amastigote form of Leishmania. The gold standard for diagnosis is a PCR test. Treatment
American cutaneous and mucocutaneous leishmaniasis
The best treatment for American cutaneous and mucocutaneous leishmaniasis (ACML) is not known. Pentavalent antimonial drugs (sodium stibogluconate (SSG) and meglumine antimonate (Glucantime, MA)) have been used since the 1940s, but they are expensive, toxic, and painful. Treatments that work for one species of Leishmania may not work for another; therefore, it is recommended that the exact species be identified prior to initiating treatment. Unfortunately, leishmaniasis is an orphan disease in developed nations, and almost all the current treatment options are toxic with significant side effects.The best-studied treatments for ACML caused by two Leishmania species are listed below. However, one should note that most of the studies examining treatments of ACML were poorly designed. Therefore, no definitive treatment guidelines or recommendations are currently available, as large-scale and well-conducted studies are necessary to evaluate the long-term effects of current treatments. Leishmania braziliensis and Leishmania panamensis: There is good evidence that oral allopurinol plus intramuscular MA is superior to either medication alone. In addition, a 20-day course of intravenous MA was better than a 7-day course as well as a 3- or 7-day course of intravenous MA with paromomycin + 12% methylbenzethonium chloride.
Glossoptosis is a medical condition and abnormality which involves the downward displacement or retraction of the tongue. It may cause non-fusion of the hard palate, causing cleft palate. It is one of the features of Pierre Robin sequence and Down syndrome. == References ==
