Mediastinal paraganglioma. The cut surface of a 3.9 × 3.5 × 2.5 cm tumor is triangular, with a bulging peripheral portion and a somewhat fibrotic center. It was surrounded by the heart, left lower lobe of the lung, aorta, esophagus, and diaphragm, and had been 1.8 cm in diameter 7 years before.
By the 1980s, unilateral exploration became more common. [10] Parathyroidectomy can now be performed in a minimally invasive fashion, mainly because imaging techniques can pinpoint the location of the tissue. [10] Minimally invasive techniques include smaller open procedures, radio-guided and video-assisted procedures, and totally endoscopic ...
An accessory spleen is a small nodule of splenic tissue found apart from the main body of the spleen. Accessory spleens are found in approximately 10 percent of the population [1] and are typically around 1 centimetre in diameter. They may resemble a lymph node or a small spleen.
The lateral aortic lymph nodes, typically 15 to 20 on each side, are the ones usually chosen for dissection or biopsy in the treatment or diagnosis of cancer.. A dissection usually includes the region from the bifurcation of the aorta to the superior mesenteric artery or the renal veins.
Calcinosis cutis can range in intensity from little nodules in one area of the body to huge, crippling lesions affecting a vast portion of the body. [1] Five kinds of the condition are typically distinguished: calciphylaxis , idiopathic calcification, iatrogenic calcification, dystrophic calcification, and metastatic calcification.
An autonomous thyroid nodule or "hot nodule" is one that has thyroid function independent of the homeostatic control of the HPT axis (hypothalamic–pituitary–thyroid axis). According to a 1993 article, such nodules need to be treated only if they become toxic; surgical excision (thyroidectomy), radioiodine therapy, or both may be used. [32]
Trauma, either by blunt force or penetration, accounts for 80% of the cases. [10] Up to a quarter of severely injured patients suffer from adrenal hemorrhage. [11] Direct compression of adrenal glands and acute intravenous pressure rise due to compression of the inferior vena cava are the two proposed mechanisms of traumatic adrenal gland ...
ICD-10 ICD-O; Nodular sclerosing HL: Is the most common subtype and is composed of large tumor nodules showing scattered lacunar classic RS cells set in a background of reactive lymphocytes, eosinophils and plasma cells with varying degrees of collagen fibrosis/sclerosis. C81.1: M9663/3: Mixed-cellularity subtype
