Leishmaniasis is a zoonotic infection acquired through the bite of a female sandfly, which introduces the amastigotes of Leishmania into the bloodstream. Cutaneous leishmaniasis is rare after solid organ transplantation. Its diagnosis is difficult in immunosuppressed patients. We report a case of isolated cutaneous leishmaniasis in a renal transplant patient resident in an endemic area. The patient was successfully treated with allopurinol and fluconazole and has remained relapse-free for 44 months. The diagnosis of cutaneous leishmaniasis must be considered in immunosuppressed patients living in endemic areas. Our report shows that cutaneous leishmaniasis may complicate the clinical course of kidney transplant recipients and its presentation can be atypical. Conventional treatment with pentavalent antimonial agents can cause many side effects; of particular concern in renal transplant patients are pancreatitis and nephrotoxicity. These latter may be avoided by using a combination of allopurinol and fluconazole.
Metastatic parapharyngeal lymph nodes (LNs) from papillary thyroid carcinomas (PTC) are uncommon and can easily remain undetected. We describe a case that involves a 62-year-old woman treated for a PTC, who presented a rise in serum thyroglobulin (TG) levels. A computed tomography scan was performed, and revealed metastatic nodes in the left parapharyngeal space (PPS). A surgical resection of the nodes was performed with external cervical approach. A histological exam confirmed the diagnosis of a metastatic LN of a PTC. The aim of this report is to emphasize on the possibility of parapharyngeal metastatic nodes in PTC and to describe the diagnosis methods, treatment options, and impact on the prognosis.
Le kyste de la vallécule est une lésion bénigne rare. Ces kystes sont souvent asymptomatiques chez l'adulte. Les auteurs rapportent 4 cas de kystes de la vallécule symptomatique de l'adulte. Trois patients ont consulté pour une dysphagie haute mixte associée à une dysphonie. Le quatrième patient se plaignait d'une sensation de corps étranger dans la gorge. La laryngoscopie a montré une formation kystique dans la région valléculaire gauche dans tous les cas. La tomodensitométrie a confirmé la présence d'une formation kystique de la vallécule. Le traitement a consisté en une marsupialisation du kyste dans deux cas et une résection endoscopique dans deux cas. À partir de ces 4 cas cliniques, nous nous proposons de préciser les particularités diagnostiques et thérapeutiques de cette affection.
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.
