| angiofollicular mediastinal lymph node hyperplasia | Solitary masses of lymphoid tissue containing concentric perivascular aggregates of lymphocytes, occurring usually in the mediastinum or hilar region of young adults; similar changes have been reported outside the mediastinum and, if associated with interfollicular sheets of plasma cells, may progress to lymphoma or plasmacytoma. Synonym: angiofollicular mediastinal lymph node hyperplasia, Castleman's disease. (05 Mar 2000) |
| anterior tibial lymph node | A small inconstant lymph node in front of the interosseous membrane along the upper part of the anterior tibial vessels. Synonym: nodus tibialis anterior, anterior tibial node. (05 Mar 2000) |
| benign giant lymph node hyperplasia | Solitary masses of lymphoid tissue containing concentric perivascular aggregates of lymphocytes, occurring usually in the mediastinum or hilar region of young adults; similar changes have been reported outside the mediastinum and, if associated with interfollicular sheets of plasma cells, may progress to lymphoma or plasmacytoma. Synonym: angiofollicular mediastinal lymph node hyperplasia, Castleman's disease. (05 Mar 2000) |
| buccal lymph node | One of the chain of facial lymph nodes located superficial to the buccinator muscle. Synonym: nodus buccinatorius, buccinator node, buccal node. (05 Mar 2000) |
| malar lymph node | One of the facial lymph nodes located near the zygomatic minor muscle. Synonym: nodus malaris, malar node. (05 Mar 2000) |
| mandibular lymph node | One of the facial lymph nodes located by the facial artery near the point it crosses the mandible. Synonym: nodus mandibularis, mandibular nodes. (05 Mar 2000) |
| paratracheal lymph node | Nodes along the sides of the trachea in the neck and in the posterior mediastinum; receive drainage of superior (and inferior) tracheobranchial (nodes, trachea and oesophagus); drain to bronchomediastinal lymphatic trunk(s), thoracic duct. Synonym: nodi lymphatici paratracheales, tracheal lymph nodes. (05 Mar 2000) |
| giant lymph node hyperplasia | Large benign, hyperplastic lymph nodes. The more common hyaline vascular subtype is characterised by small hyaline vascular follicles and interfollicular capillary proliferations. Plasma cells are often present and represent another subtype with the plasma cells containing IgM and IgA. (12 Dec 1998) |
| medial lacunar lymph node | A lymph node of the external iliac group located medial to the external iliac vein at the vascular lacuna. Synonym: nodus lacunaris medialis, medial lacunar node. (05 Mar 2000) |
| medulla of lymph node | The central portion of a node consisting of cordlike masses of lymphocytes, plasma cells, and macrophages in a stroma of reticular fibres separated by lymph sinuses; it reaches the surface of the node at the hilum. Synonym: medulla nodi lymphatici. (05 Mar 2000) |
| middle rectal lymph node | A lymph node along the middle rectal artery that receives afferents from the pararectal nodes and sends efferents to the internal iliac nodes. Synonym: middle rectal node, nodus rectalis medius. (05 Mar 2000) |
