Descriptor timoma
Entry term(s) carcinoma tímico
Scope note: Neoplasia que se origina en el tejido tímico, por lo común benigno y con frecuencia capsulado. Aunque es ocasionalmente invasivo, las metástasis son extremadamente raras. Se compone de cualquier tipo de células epiteliales tímicas, así como linfocitos que suelen ser abundantes. Los linfomas malignos que implican el timo, por ejemplo, el linfosarcoma, la enfermedad de Hodgkin (anteriormente denominada timoma granulomatoso), no deben considerarse como timoma.

Scope note: A neoplasm originating from thymic tissue, usually benign, and frequently encapsulated. Although it is occasionally invasive, metastases are extremely rare. It consists of any type of thymic epithelial cell as well as lymphocytes that are usually abundant. Malignant lymphomas that involve the thymus, e.g., lymphosarcoma, Hodgkin's disease (previously termed granulomatous thymoma), should not be regarded as thymoma. (From Stedman, 25th ed)
