  2. Thymoma - Wikipedia

    en.wikipedia.org/wiki/Thymoma

    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);

  3. Thymus - Wikipedia

    en.wikipedia.org/wiki/Thymus

    This process continues into old age, where whether with a microscope or with the human eye, the thymus may be difficult to detect, [4] although typically weighs 5–15 grams. [3] Additionally, there is an increasing body of evidence showing that age-related thymic involution is found in most, if not all, vertebrate species with a thymus ...

    en.wikipedia.org/wiki/Outline_of_human_anatomy

    Gross anatomy (also called topographical anatomy, regional anatomy, or anthropotomy) is the study of anatomical structures that can be seen by unaided vision. Microscopic anatomy is the study of minute anatomical structures assisted with microscopes, and includes histology (the study of the organization of tissues), and cytology (the study of ...

  6. Granulation tissue - Wikipedia

    en.wikipedia.org/wiki/Granulation_tissue

    Granulation tissue is new connective tissue and microscopic blood vessels that form on the surfaces of a wound during the healing process. [1] Granulation tissue typically grows from the base of a wound and is able to fill wounds of almost any size. Examples of granulation tissue can be seen in pyogenic granulomas and pulp polyps.

  7. Thymic carcinoma - Wikipedia

    en.wikipedia.org/wiki/Thymic_carcinoma

    Compared to thymoma, the cells of thymic carcinoma behave aggressively; they are fast growing and have a higher likelihood of systemic spread. [ 4 ] The World Health Organization separates thymoma into categories from type A to C based on histology, with type C thymoma representing the equivalent of thymic carcinoma. [ 3 ]

  8. Thymoma-associated multiorgan autoimmunity - Wikipedia

    en.wikipedia.org/wiki/Thymoma-associated_multi...

    Thymoma is a common neoplasm arising from the thymus, the primary lymphoid organ where T cells become educated to distinguish "self" from "non self". In the setting of thymoma, abnormal thymic education occurs as a result of subtle differences in antigen processing. In TAMA these differences result in autoreactive T cells escaping from the thymus.

  9. Mediastinal tumors - Wikipedia

    en.wikipedia.org/wiki/Mediastinal_tumors

    Tonofibrils seen under electron microscopy can differentiate thymoma from other tumors such as carcinoid, Hodgkin's, and seminoma. Patients are usually asymptomatic but can present with myasthenia gravis-related symptoms, substernal pain, dyspnea, or cough. Invasive tumors can produce compression effects such as superior vena cava syndrome.
