Hassall's corpuscles (also known as thymic bodies) are structures found in the medulla of the human thymus, formed from eosinophilic type VI thymic epithelial cells arranged concentrically. These concentric corpuscles are composed of a central mass, consisting of one or more granular cells, and of a capsule formed of epithelioid cells.
Thymoma originates from the epithelial cell population in the thymus, and several microscopic subtypes are now recognized. [2] There are three principal histological types of thymoma, depending on the appearance of the cells by microscopy: Type A if the epithelial cells have an oval or fusiform shape (less lymphocyte count);
The branches reach the thymus and travel with the septa of the capsule into the area between the cortex and medulla, where they enter the thymus itself; or alternatively directly enter the capsule. [2] The veins of the thymus, the thymic veins, end in the left brachiocephalic vein, internal thoracic vein, and in the inferior thyroid veins. [2]
Gross anatomy (also called topographical anatomy, regional anatomy, or anthropotomy) is the study of anatomical structures that can be seen by the naked eye. [1] Microscopic anatomy is the study of minute anatomical structures assisted with microscopes , which includes histology (the study of the organization of tissues), [ 1 ] and cytology ...
The following outline is provided as an overview of and topical guide to human anatomy: Human anatomy is the scientific study of the morphology of the adult human. It is subdivided into gross anatomy and microscopic anatomy. Gross anatomy (also called topographical anatomy, regional anatomy, or anthropotomy) is the study of anatomical ...
TECs, as a component of the thymus, play a key role in thymocyte development and self-tolerance, so their dysfunction causes many autoimmune diseases, tumors of immunodeficiencies. Most frequently are occurred epithelial tumors established from TEC and thymocytes - thymomas and thymic carcinoma .
It contains the heart, esophagus, trachea, thymus, and aorta. The most common mediastinal masses are thymoma (20% of mediastinal tumors), usually found in the anterior mediastinum, followed by neurogenic Timor (15–20%) located in the anterior mediastinum. [1] Lung cancer typically spreads to the lymph nodes in the mediastinum.
