Jessner lymphocytic infiltrate of the skin is a cutaneous condition characterized by a persistent papular and plaque-like skin eruption which can occur on the neck, face and back and may re-occur. This is an uncommon skin disease and is a benign collection of lymph cells. Its cause is not known and can be hereditary.
Lymphoid hyperplasia is the rapid proliferation of normal lymphocytic cells that resemble lymph tissue which may occur with bacterial or viral infections. [1] The growth is termed hyperplasia which may result in enlargement of various tissue including an organ, or cause a cutaneous lesion .
Lymphoproliferative disorders (LPDs) refer to a specific class of diagnoses, comprising a group of several conditions, in which lymphocytes are produced in excessive quantities. These disorders primarily present in patients who have a compromised immune system .
In immunology, immunoproliferative disorders are disorders of the immune system that are characterized by the abnormal proliferation of the primary cells of the immune system, which includes B cells, T cells and natural killer (NK) cells, or by the excessive production of immunoglobulins (also known as antibodies).
Lymphadenopathies such as follicular hyperplasia can show various symptoms such as fever, chills, night sweats, unexplained weight loss and prominent localizing symptoms are non age and non-gender specific. [4] Although human lymph nodes cannot be seen with the naked eye, if you press against the skin you can sometimes feel for swelling and ...
Cutaneous B-cell lymphomas (CBCL), more recently termed Primary cutaneous B-cell lymphomas and lymphoproliferative disorders (PCBCLPD), are a group of disorders that typically present as skin lesions consisting of proliferating B-cells. B-cells are a type of lymphocyte involved in regulating immune responses.
Similar to cutaneous anaplastic large-cell lymphoma, with larger clusters or sheets of large anaplastic CD30+ cells without the interspersed mixed infiltrate of Type A. D Similar to CD8+ epidermotropic cutaneous T-cell lymphoma , with large CD8 + and CD30+ lymphocytes that often stain with cytotoxic markers (TIA-1, granzyme, perforin).
Epidermotropism (lymphocytes residing in the epidermis) [6] by neoplastic CD4+ lymphocytes with the formation of Pautrier's microabscesses is the hallmark sign of the disease. Although the condition can affect people of all ages, it is commonly diagnosed in adults over age 60. [7] [3] The dominant signs and symptoms of the disease are:
