SHOTTY LYMPH NODES HIV SKIN

Infection-related lymphedema is more common in developing countries in tropical and subtropical regions. Damage to the inguinal lymph node can present with lymphedema of the lower limb. Lymphedema is the swelling that typically occurs in the arm or leg due to the lymph vessels unable to drain lymph fluid sufficiently. Fifty percent of infected individuals present with tender inguinal lymphadenopathy along with ulcers with exudate. Ĭhancroid is a rare sexually transmitted disease caused by a small gram-negative rod, Haemophilus ducreyi.

Clinical presentation of secondary syphilis can present with diffuse lymphadenopathy along with fever, skin rashes, and condylomata lata. Syphilis is a bacterial infection caused by the spirochete Treponema pallidum. The secondary stage of lymphogranuloma venereum can present with unilateral or bilateral tender inguinal lymphadenopathy. Lymphogranuloma venereum primarily affects the lymphatic system and has three stages. Lymphogranuloma venereum is a disease of the genital area caused by the gram-negative bacteria Chlamydia trachomatis (serovars L1, L2, and 元). Sexually transmitted infections that commonly presents with inguinal lymphadenopathy are lymphogranuloma venereum, secondary syphilis, and chancroid caused by Chlamydia trachomatis(L1-元), Treponema pallidum, and Haemophilus ducreyi, respectively. One of the more concerning causes of inguinal lymphadenopathy is sexually transmitted infections. Swollen inguinal lymph nodes could indicate an infection of areas of the lower body. Swollen lymph nodes usually indicate infection from bacteria or viruses. The superficial and deep inguinal lymph nodes both drain into the external iliac lymph nodes. The deep nodes receive drainage from the glans penis or clitoris, as well as the superficial lymph nodes. The deep inguinal lymph nodes are within the femoral sheath medial to the femoral vein. The superficial inguinal lymph nodes drain the anal canal(below the pectinate line), the skin below the umbilicus, lower extremity, scrotum, and vulva. The superficial inguinal lymph nodes reside below the inguinal ligament and subdivide into the inferior, superolateral, and superomedial nodes. The inguinal lymph nodes are in the groin area and classify as superficial and deep. Lymph nodes are located throughout the body and can be found deep within tissues and superficially and drain specific areas of the body. Macrophages phagocytize pathogens such as bacteria and viruses and destroy them. T-cell lymphocytes are responsible for cell-mediated immunity. The antibodies tagged the antigen for destruction by other immune cells.

Activated primary follicles form into secondary follicles called germinal centers and indicate the proliferation of B-lymphocytes and the production of antibodies. If there is a presence of an antigen, B-cell lymphocyte in the follicles create antibodies that are specific to the antigen. As the fluid travels through the lymph node, immune cells within the node filter for harmful substances such as bacteria, viruses, parasites, and other foreign material. Lymph node has afferent vessels that carry lymphatic fluid to the lymph node. The medulla contains reticular cells and macrophages and communicates with efferent lymphatic vessels. The paracortex houses T-cell lymphocytes. Each lobule divides into separate compartments cortex, paracortex, and medulla-the cortex houses primary follicles, which are dormant B- cell lymphocytes.

Different lymph node size has a different number of lobules. The fibrous capsule extends into the lymph node to form trabeculae and divide each node into lobules. A tough fibrous connective tissue capsule encapsulates lymph nodes. Lymph nodes play a vital role in the body’s ability to fight off infection. Lymph nodes are small, round kidney-shaped structures that run with the lymphatic system.
