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.
Accessory spleens may be formed during embryonic development when some of the cells from the developing spleen are deposited along the path from the midline, where the spleen forms, over to its final location on the left side of the abdomen by the 9th–11th ribs. The most common locations for accessory spleens are the hilum of the spleen and ...
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 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]
In the cases with underlying tumors, benign lesions including adrenal cyst and myelolipoma bigger than 10 cm may spontaneously bleed into the adrenal gland or retroperitoneum. Massive bleeding from a primary adrenal tumor could be fatal in up to half of the reported cases, which are most resulted from pheochromocytoma. [14]
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
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.
Hashimoto's thyroiditis, also known as chronic lymphocytic thyroiditis, Hashimoto's disease, and autoimmune thyroiditis is an autoimmune disease in which the thyroid gland is gradually destroyed.
