| lymphoepithelioma | <tumour> A poorly differentiated radiosensitive squamous cell carcinoma involving lymphoid tissue in the region of the tonsils and nasopharynx; composed of irregular sheets, or small groups, of neoplastic epithelial cells (squamous or undifferentiated), with a slight to moderate amount of fibrous stroma that contains numerous lymphocytes; metastasizes at an early stage to cervical lymph nodes. Origin: Lympho-+ epithelium + -oma, tumour (05 Mar 2000) |
| lymphogenesis | Lymph production. Origin: Lympho-+ G. Genesis, production (05 Mar 2000) |
| lymphogenic | <physiology> Connected with, or formed in, the lymphatic glands. Origin: Lymph + root of L. Gignere to produce. Source: Websters Dictionary (01 Mar 1998) |
| lymphogenous | 1. Originating from lymph or the lymphatic system. Synonym: lymphogenic. 2. Producing lymph. (05 Mar 2000) |

| lymphoglandula | <anatomy> Small bean-shaped organ made up of a loose meshwork of reticular tissue in which are enmeshed large numbers of lymphocytes, macrophages and accessory cells located along the lymphatic system. Recirculating lymphocytes leave the blood through the specialised high endothelial venules of the lymph node and pass through the node before being returned to the blood through the lymphatic system. Because the lymph nodes act as drainage points for tissue fluids, they are also regions in which foreign antigens present in the tissue fluid are most likely to begin to elicit an immune response. Nodes filter out bacteria or cancer cells that may travel through the lymphatic system. Synonym: lymph glands. (14 Oct 1997) |
| lymphogranuloma | 1. Old non-specific term used with reference to a few basically dissimilar diseases in which the pathologic processes result in granulomas or granuloma-like lesions, especially in various groups of lymph nodes (which then become conspicuously enlarged). 2.

| lymphogranuloma inguinale | A venereal infection usually caused by Chlamydia trachomatis, and characterised by a transient genital ulcer and inguinal adenopathy in the male; in the female, perirectal lymph nodes are involved and rectal stricture is a common occurrence. Synonym: climatic bubo, Favre-Durand-Nicholas disease, lymphogranuloma inguinale, Nicolas-Favre disease, sixth venereal disease, tropical bubo. (05 Mar 2000) |
| lymphogranuloma malignum | Old term for Hodgkin's disease. (05 Mar 2000) |
| lymphogranuloma venereum | <gynaecology> A sexually transmitted bacterial disease that is caused by the micro-organism Chlamydia trachomatis. Symptoms usually begin 1-3 weeks after contact. Symptoms include lymph node swelling in the groin, fever, headache, chills and skin ulcers (or bumps) on the genitalia. (27 Sep 1997) |
| lymphogranuloma venereum antigen | A sterile preparation of inactivated chlamydiae grown in the yolk sac of domestic fowl and used as an antigen in the Frei test. (05 Mar 2000) |
