Thymoma and thymic germinal center.
A previous study of 70 cases of thymoma described in 1966 by the author1 reported that definite germinal centers were found in the normal thymic tissue attached to one case of thymoma associated with myasthenia gravis, and that this was very interesting from the point of view of whether thymoma or thymic germinal center was a more important occurrence of a myasthenic condition. Since then routi...
متن کاملThymoma and thymic carcinoma.
Thymic tumors comprise a heterogeneous group of neoplasms with a wide spectrum of clinical presentations. The evolution of the disease is often unpredictable, ranging from an indolent attitude to the possibility of intra- and extrathoracic spread. From the histological point of view, thymoma and thymic carcinoma are the most frequent subtypes and arise only from thymic epithelial cells. Other h...
متن کاملNovel Treatments for Thymoma and Thymic Carcinoma
The rarity of thymic epithelial tumors (TETs) creates unique challenges in conducting translational research and developing newer paradigms of treatment (1). Nevertheless, steady progress in genome research, the development of thymic cell lines, and an increase in collaborative efforts between various institutions have helped in fostering an increase in the understanding of the biology of TETs ...
متن کاملThymic carcinoid tumor combined with thymoma--neuroendocrine differentiation in thymoma?
A carcinoid tumor of the thymus combined with thymoma in a 62-year-old man is described. The mediastinal tumor had been present for 13 years and was associated with pure red cell aplasia. Carcinoid tumor occupied the central two-thirds of the tumor, consisting of nests and trabeculae of monotonous round cells, which ultrastructurally showed many intracytoplasmic dense-core granules. Typical spi...
متن کاملWell-Differentiated Thymic Epithelial Neoplasms (Thymoma)
(atypical thymoma); and those showing total loss of the organotypical features of the thymus and displaying overt cytologic evidence of malignancy correspond to high-grade or poorly differentiated thymic epithelial neoplasms (also designated, by convention, thymic carcinoma) (2,4). The grading is based on a combination of architectural and cytological parameters as observed on routine microscop...
