A paraganglioma is a rare neuroendocrine neoplasm that may develop at various body sites (including the head, neck, thorax and abdomen). When the same type of tumor is found in the adrenal gland, they are referred to as a pheochromocytoma. They are rare tumors, with an overall estimated incidence of 1 in 300,000. [1]
Differential diagnosis of an enlarged Virchow's node includes lymphoma, various intra-abdominal malignancies, breast cancer, and infection (e.g. of the arm). Similarly, an enlarged right supraclavicular lymph node tends to drain thoracic malignancies such as lung and esophageal cancer, as well as Hodgkin's lymphoma.
[9] [10] Symptoms may include fever, night sweats, and weight loss. [2] Often, nonpainful enlarged lymph nodes occur in the neck, under the arm, or in the groin. [2] Persons affected may feel tired or be itchy. [2] The two major types of Hodgkin lymphoma are classic Hodgkin lymphoma and nodular lymphocyte-predominant Hodgkin lymphoma. [5]
The classification of the cervical lymph nodes is generally attributed to Henri Rouvière in his 1932 publication "Anatomie des Lymphatiques de l'Homme" [6] [7] Rouviere described the cervical lymph nodes as a collar which surrounded the upper aerodigestive tract, consisting of submental, facial, submandibular, parotid, mastoid, occipital and retropharyngeal nodes, together with two chains ...
Patients may not be experiencing any noticeable symptoms but could be producing excessive amounts of calcium and eventually experience problems later in life if untreated. However, if symptomatic, patients can experience: pain or discomfort in the joints, muscles, and abdomen; depression and mood changes due to the hormonal imbalance.; [ 4 ...
Melson's syndrome is a disorder that occurs in about one in four patients who have had both adrenal glands removed to treat extreme slackness. [1] In patients with pre-existing adrenocorticotropic hormone ()-secreting pituitary adenomas, loss of adrenal feedback following bilateral adrenalectomy can trigger the rapid growth of the tumor, leading to visual symptoms (e.g. bitemporal hemianopsia ...
The left paraaortic nodes form a chain on the left side of the abdominal aorta in front of the origin of the psoas major and on the left crus of the diaphragm. The paraaortic and retroaortic nodes receive: (a) the efferents of the common iliac lymph nodes
Bilateral adrenal hemorrhage is the condition when bleeding occurs in both adrenal glands, which could be instantly life-threatening. Over half of the bilateral cases are related to acute stress, such as infection, congestive myocardial infarction , complications of pregnancy, surgery or invasive procedure.
