ABSTRACT

Los quistes tímicos son lesiones poco frecuentes. La mayoría se presenta en las primeras décadas de la vida, aunque pueden estar presentes desde el nacimiento. Otros se descubren incidentalmente en radiografías torácicas y autopsias y pueden confundirse con tumores malignos. Se reporta 1 caso, con hemorragia antigua y granulomas de colesterol, en el estudio necrópsico de una anciana de 71 años de edad, localizado en la porción anterosuperior del mediastino, no relacionado con su fallecimiento, el cual fue por infarto miocárdico agudo. El estudio histológico de la pieza reveló la naturaleza tímica del proceso. Se discuten los aspectos microscópicos del caso y se precisa su diagnóstico diferencial con otros tumores del mediastino(AU)


Thymic cysts are uncommon lesions. Most of them occur in the first decade of life, although they may be present at birth. Other thymic cysts are incidentally discovered in chest X-rays and in autopsy and may be mistaken for malignant tumors. It is reported the case of a woman aged 71 with an old hemorrhage and cholesterol granuloma detected by necropsy study, where a cyst was located in the mediastinum anteroposterior portion.. It was not related to her death, since she died from acute myocardial infarction. The histologic study of the cyst revealed the thymic nature of the process. The microscopic features of the case are discussed and its differential diagnosis is specified in relation to other mediastinal tumors(AU)
