Diffuse coexpression of thyroid transcription factor-1 and p40 in a non-small cell carcinoma of the lung: Second case in the female population / Coexpresión difusa del factor de transcripción tiroidea 1 y p40 en un carcinoma de célula no pequeña del pulmón: segundo caso en la población de sexo femenino

Some non-small cell carcinomas of the lung can express TTF1 and p40 in the same tumor cells. This event has been described in only six cases prior to this one, and only in one other female. It is an extraordinary event that appears as a new entity yet to be defined. The case presented is a woman with a non-small cell lung carcinoma with diffuse coexpression of TTF1 and p40 in the same cells. (AU)

Este evento se ha descrito únicamente en 6 casos anteriores a este, y solo en otra persona del sexo femenino. Se trata de un evento extraordinario que se muestra como una nueva entidad todavía por definir. El caso que se presenta versa sobre una mujer con un carcinoma de pulmón de célula no pequeña con coexpresión difusa en las mismas células de TTF1 y p40. (AU)

Villitis crónica granulomatosa asociada a citomegalovirus. Un hallazgo inusual que induce a confusión. A propósito de un caso / Chronic granulomatous villitis due to cytomegalovirus. An unusual finding that may cause confusion. A case report

La villitis crónica por citomegalovirus (CMV) cursa típicamente con inflamación de células plasmáticas. La reacción granulomatosa en el árbol velloso placentario está generalmente causada por patógenos distintos del CMV, como el toxoplasma o la rubéola. Se presenta el caso de una paciente con un feto sin latido cardíaco en la semana 20de embarazo. El estudio de su placenta reveló una villitis crónica por CMV, en la que se observa una reacción granulomatosa, en lugar de la típica inflamación de células plasmáticas.(AU)

Chronic cytomegalovirus (CMV) villitis typically causes inflammation with predominance of plasma cells. The granulomatous reaction in the chorionic villi is usually caused by pathogens other than CMV, such as toxoplasma or rubella. We present a case of a pregnant woman presenting with foetal death in the twentieth week of gestation. The study of the placenta revealed chronic CMV villitis with a granulomatous reaction, rather than the more common plasma cell inflammation.(AU)
