%X Hombre de 21 a os de edad de raza negra, natural del Choc車 (Colombia), quien ha desempe ado diversos oficios; present車 un s赤ndrome de dificultad respiratoria de dos meses de evoluci車n, dolor pleur赤tico derecho, insuficiencia card赤aca congestiva y s赤ntomas sist谷micos. En la necropsia se encontr車 una masa tumoral blanco-gris芍cea de 10 x 8 cm, homog谷nea, con 芍reas de necrosis, originada en el bronquio principal de los l車bulos inferior y medio derechos y que invadi車 por vecindad en forma de coraza todo el pericardio causando una pericarditis constrictiva tumoral. El estudio microsc車pico correspondi車 a un carcinoma broncog谷nico tipo epidermoide bien diferenciado. El carcinoma broncog谷nico se asocia frecuentemente con el consumo de cigarrillo pero su incidencia ha c.umentado entre las personas no fumadoras, lo que sugiere la posibilidad de otros factores que influyen en su presentaci車n como son los contaminantes atm車sf谷ricos, la predisposici車n gen谷tica, la dieta deficiente en vitamina A y carotenos, la presencia de ciertos virus y cambios inmunol車gicos. Este tumor constituye el 16% de todos los c芍nceres en el hombre y e113% en las mujeres; aparece con mayor frecuencia entre los 40 y los 70 a os y s車lo del1 al 5% de los casos se presenta en menores de 40 a os. A 21 year cid black man, native from Choc車 (Colombia), variously employed, who presented with a respiratory difficulty syndrome of two months of evolution, right pleuritic pain, congestive cardiac failure and systemic symptoms. A homogeneic white .grayish tumor measuring 8 by 10 cm with necrotic areas was found at necropsy. The tumor originated in the main bronchial tube of the lower and middle lobes of the right lung and invaded the entire pericardial vicinity forming a cuirass and causing tumoral constrictive pericarditis. Microscopic studies revealed a well differentiated squamous type bronchogenic carcinoma. Bronchogenic carcinomas are frequently associated with cigarette smoking. However, their incidente has increased among non. smokers, suggesting the possibility that there are other causal factors, such as atmospheric contaminants, genetic predisposition, diets deficient in vitamin A and carotene, presente of certain viruses and immunologic changes. Lung cancer constitutes 16% among the types of cancer suffered by men and 13% among women, it has its greatest incidente in groups between 40 and 70 years of age and only 1 to 5 percent of thecasesoccur in groupsunder theageofforty years.
