#SHOTTY LYMPH NODE SKIN#

Nodes are generally considered to be normal if they are up to 1 cm in diameter however, some authors suggest that epitrochlear nodes larger than 0.5 cm or inguinal nodes larger than 1.5 cm should be considered abnormal These are also known as 'Shotty Lymph nodes'. Sometimes, following infection lymph nodes occasionally remain permanently enlarged, though they should be non-tender, small (less the 1 cm), have a rubbery consistency and none of the characteristics described for malignancy or for infection. Lymph nodes harboring malignant disease tend to be firm, non-tender, matted (i.e., stuck to each other), fixed (i.e., not freely mobile but rather stuck down to underlying tissue), and increase in size over time. Inflammation can spread to the overlying skin, causing it to appear reddened. Infected Lymph nodes tend to be firm, tender, enlarged and warm. * Common causes of enlargement: Lymphoma, thoracic or retroperitoneal cancer, bacterial or fungal infection.Ĭlinical features of abnormal lymph node enlargementĪbnormal lymph node enlargement tends to commonly result from infection / immune response, cancer and less commonly due to infiltration of macrophages filled with metabolite deposits (e.g., storage disorders). * Lymphatic drainage: Thorax, abdomen via thoracic duct.

* Location: Located on the left side in the hollow above the clavicle, just lateral to where it joins the sternum. * Common causes of enlargement: Lung, retroperitoneal or gastrointestinal cancer * Lymphatic drainage: Mediastinum, lungs, esophagus * Location: Located on the right side in the hollow above the clavicle, just lateral to where it joins the sternum. * Common causes of enlargement: External auditory canal infection. * Lymphatic drainage: Eyelids and conjunctivae, temporal region, pinna * Location: Located in front of the ears. * Lymphatic drainage: External auditory meatus, pinna, scalp * Common causes of enlargement: Local infection * Location: Located at the junction between the back of the head and neck. * Common causes of enlargement: Tuberculosis, lymphoma, head and neck malignancy

#SHOTTY LYMPH NODE SKIN#

* Lymphatic drainage: Scalp and neck, skin of arms and pectorals, thorax, cervical and axillary nodes * Location: Extend in a line posterior to the sternocleidomastoid muscles but in front of the trapezius, from the level of the mastoid bone to the clavicle (on the side of the neck near to the back).

* Common causes of enlargement: Pharyngitis organisms, rubella * Lymphatic drainage: Tongue, tonsil, pinna, parotid * Location: Nodes that lie both on top of and beneath the sternocleidomastoid muscles (SCM) on either side of the neck, from the angle of the jaw to the top of the clavicle. * Common causes of enlargement: Mononucleosis syndromes, Epstein-Barr virus, cytomegalovirus, toxoplasmosis, dental pathology such as periodontitis. * Lymphatic drainage: Lower lip, floor of mouth, teeth, submental salivary gland, tip of tongue, skin of cheek.

* Common causes of enlargement: Infections of head, neck, sinuses, ears, eyes, scalp, pharynx. * Lymphatic drainage: Tongue, submaxillary gland, lips and mouth, conjunctivae. * Location: Along the underside of the jaw on either side. If lymph nodes in other areas (e.g., the arm pits) are also enlarged in addition to those in the neck, then the condition should be evaluated as a case of generalized lymphadenopathy. Localized cervical lymphadenopathy (disease of the lymph nodes) presents with lymph node enlargement that is restricted to the cervical (neck) area. Findings from this Dutch study revealed a 0.6 percent annual incidence of unexplained lymphadenopathy in the general population.Ĭauses of cervical (neck) lymph node enlargement Only one study provides reliable population-based estimates. These groups are responsible for draining lymphatic fluid from different areas (Regions) in the head and neck. Lymph nodes in the head and neck form groups.
