RESUMO
Chagas disease continues to cause substantial morbidity and mortality in endemic areas in Latin America. Although there have been some well documented successes in halting the transmission of Chagas disease through preventive interventions to decrease vector-borne and blood-transfusion cases, this parasitic infection continues to be transmitted through these routes in some areas as well through perinatal and foodborne routes. In addition, transmission through solid-organ transplantation has been described in nonendemic settings due to the increasing globalization of Chagas disease to the United States of America, Europe, and other areas. Because there has been a concomitant increase in the number of solid-organ transplantations performed in Latin American settings endemic for American trypanosomiasis, there is increasing concern for the potential reactivation of Trypanosoma cruzi in a previously infected recipient and as a result of aggressive immunosuppression; or via transmission from organs donated by a latently infection donor transplanted onto an uninfected recipient. In this study, we report 2 cases of Chagas disease reactivation in 2 solid-organ transplant recipients in Northeastern Colombia, and we discuss the implications for screening as a crucial strategy for preventing transmission in endemic settings.
RESUMO
El carcinoma escamocelular puro primario de vesícula biliar es una neoplasia infrecuente cuya etiología y fisiopatología no están totalmente aclarados. A continuación se presenta el caso de un paciente de género femenino de 68 años de edad, quien presentó un cuadro clínico caracterizado por dolor tipo cólico en hipocondrio derecho, acompañado de náuseas, vómito y fiebre no cuantificada. Se le realizaron pruebas diagnósticas que no fueron concluyentes, por lo cual se ordenó una colecistectomía que reveló un carcinoma escamocelular puro primario de vesícula biliar, que al estudio macro y microscópico revelaba un aumento del volumen del órgano que se asociaba a una distorsión de la arquitectura normal, reemplazada por lesión tumoral infiltrativa. Por tratarse de una variante infrecuente de carcinoma de vesícula biliar, se reporta este caso, además de las dificultades clínicas que genera su diagnóstico.
Primary pure squamous cell carcinoma of the gallbladder is a rare neoplasm whose etiology and pathophysiology are incompletely understood. Here is a case of a 68-year-old female patient, who presented a clinical picture characterized by crampy pain in right hypochondrium, accompanied by nausea, vomiting and unquantified fever, diagnostic tests was performed but it was not so conclusive, for this reason, cholecystectomy was ordered and this revealed a primary pure squamous cell carcinoma of the gallbladder, macro and microscopic study revealed an increased volume of the organ that was associated with a distortion of normal architecture, replaced by diffuse infiltrative tumor. This variant of carcinoma is not common, so is reported this case, besides the clinical difficulties generated by the diagnosis.
