Nodules

Nodule (medicine) In medicine, nodules are small firm lumps, usually greater than 1 cm in diameter. If filled with fluid they are referred to as cysts. Smaller (less than 0.5 cm) raised soft tissue bumps may be termed papules Thyroid nodules are solid or fluid-filled lumps that form within your thyroid, a small gland located at the base of your neck, just above your breastbone. Most thyroid nodules aren't serious and don't cause symptoms In sedimentology and geology, a nodule is a small, irregularly rounded knot, mass, or lump of a mineral or mineral aggregate that typically has a contrasting composition, such as a pyrite nodule in coal, a chert nodule in limestone, or a phosphorite nodule in marine shale, from the enclosing sediment or sedimentary rock A mass of compact, densely staining lymphocytes forming the structural unit of lymphatic tissue. These nodules may occur singly, in groups (as in Peyer's patches), or in encapsulated organs such as lymph nodes. Each contains a lighter-staining germinal center where new lymphocytes are formed

Definition of nodule. : a small mass of rounded or irregular shape: such as. a : a small rounded lump of a mineral or mineral aggregate. b : a swelling on a leguminous root that contains symbiotic bacteria Vocal nodules are hard, rough, noncancerous growths on your vocal cords. They can be as small as a pinhead or as large as a pea. You get nodules from straining or overusing your voice, especially.

Nodule. Nodules formed by accumulations of microcrystalline calcite may exhibit a clotted fabric, i.e. a flocculent structure which appears as coalescing irregular or rounded clusters (pellets) with an homogeneous micritic internal fabric (Tandon & Friend, 1989) or a mottled fabric (patches of various colours) (Wright & Tucker, 1991) (globular halos) reflecting the complex and. Pulmonary nodules are small, rounded opacities within the pulmonary interstitium . Pulmonary nodules are common and, as the spatial resolution of CT scanners has increased, detection of smaller and smaller nodules has occurred, which are more often an incidental finding. On this page Nodule, rounded mineral concretion that is distinct from, and may be separated from, the formation in which it occurs. Nodules commonly are elongate with a knobby irregular surface; they usually are oriented parallel to the bedding Nodules are spiculated—have irregular or lobular borders. Nodules are solid. Nodules grow rapidly (on average doubling in size in four months) Nodules show no signs of calcification. Nodules are not cavitary. Presence of multiple nodules (suspicious for cancer metastases to the lungs) Nodules are located in left or right upper lobes of the lung

lymphoid tissue. These are referred to as nodules and are not to be confused with nodes, an entirely different structure. Some nodules become relatively permanent structures, such as the tonsils, appendix, and Peyer's patches, which are in the lining of the small intestine Stomach nodules describe multiple small, solid areas on the lining of the stomach. There are many different possible causes of these nodules, including cancer, inflammation, and ulcers. Symptoms of nodule growth include abdominal pain, bleeding, or a feeling of being full very quickly after eating.

Less commonly, nodules may form in the eyes, lungs and vocal cords but these represent severe cases. Furthermore, rheumatoid nodules can vary in size and shape. Most nodules have a circular shape, however, some can be linear in shape as well. Also, they can range from small and pea-sized to as large as a walnut A small, rounded lump of a mineral or mixture of minerals that is distinct from and usually harder than the surrounding rock or sediment. Nodules often form by replacement of a small part of the rocks in which they form. The American Heritage® Science Dictionary Copyright © 2011 Rheumatoid nodules are masses of inflammatory tissue. They can be a single mass or a cluster of what are called micro-nodules. When multiple nodules form in one location, this is called accelerated nodulosis Nodules develop more often in people who have a family history of nodules, and in people who don't get enough iodine. Iodine is needed to make thyroid hormone. There are different types of thyroid nodules: Colloid nodules: These are one or more overgrowths of normal thyroid tissue. These growths are benign (not cancer) Pulmonary Nodules. Many people have lung nodules. These abnormal growths are rarely cancerous. Respiratory illnesses and infections can cause nodules to form in the lungs. Most lung nodules are not a sign of lung cancer and don't require treatment. On X-rays or scans, these growths may look like a shadow or spot on the lung

Seeing how it looks on the CT scan Rheumatoid nodules are common in RA and appear in approximately 25% of patients. 78 Rheumatoid nodules favor subcutaneous tissues at pressure points, such as adjacent to bony protuberances. The posterior elbow is a common location. Nodules usually have an insidious onset and may persist unchanged for years The term thyroid nodule refers to an abnormal growth of thyroid cells that forms a lump within the thyroid gland. Although the vast majority of thyroid nodules are benign (noncancerous), a small proportion of thyroid nodules do contain thyroid cancer. In order to diagnose and treat thyroid cancer at the earliest stage, most thyroid nodules need.

Polymetallic nodules were discovered more than a century ago. In the 1970s, four consortia started to collect the rocks in trials. Tests confirmed that the nodules could be collected and processed to produce usable metals with the technology available at the time, but the activity was paused because there were no regulations or governing body in place to protect the deep ocean, especially in. Nodules: A small mass of tissue in the form of a protuberance or a knot that is solid and can be detected by touch. Mentioned in: Lepros Lymph nodules frequently contain germinal centres—sites for localized production of lymphocytes. In the small intestine, collections of lymph nodules are called Peyer's patches. The tonsils are also local regions where the nodules have merged together

Prurigo nodularis (PN) is a skin disease that causes hard, itchy lumps ( nodules) to form on the skin. [1] The itching ( pruritus) can be intense, causing people to scratch themselves to the point of bleeding or pain. Scratching can cause more skin lesions to appear. [2] [3] The itching is worsened by heat, sweating, or irritation from clothing. Lung nodules are small growths on the lungs. They are very common, can be benign or malignant, and often do not cause symptoms. They usually show up on a chest X-ray or CT scan. Read more here

Lung adenocarcinomas (LUAD) that radiologically display as subsolid nodules (SSNs) exhibit more indolent biological behavior than solid LUAD. The transcriptomic features and tumor microenvironment (TME) of SSN remain poorly understood. Here, we performed single-cell RNA sequencing analyses of 16 SSN samples, 6 adjacent normal lung tissues (nLung), and 9 primary LUAD with lymph node metastasis. Introduction. The advent of CT screening for lung cancer has increased the incidence of ground-glass nodules (GGNs). GGNs, especially part-solid GGNs, are more likely to be lung cancer than solid nodules. 1-4 Furthermore, most part-solid GGNs are confirmed as minimally invasive adenocarcinomas or invasive adenocarcinomas, often requiring surgical resection. 5,6 Although GGNs have a high.

The nodules contain nickel, copper, and cobalt (around 2 - 3% of the nodule weight) as well as traces of other metals such as molybdenum, Rare Earth Elements and lithium, which are important to high-tech industries. The amount of copper contained in the CCZ nodules is estimated to be about 20% of that held in global land-based reserves The nodules lie on the sea-bottom sediment, generally half buried. Some nodules are completely covered by sediment and, in some areas, nodules have been collected even t hough they are invisible on photographs. They vary greatly in abundance. In some places they cover more than 70 per-cent of the bottom, the nodules touching one another These nodules, with a size ranging from that of a potato to a head of lettuce, contain mainly manganese, as their name suggests, but also iron, nickel, copper, titanium and cobalt.

Thyroid nodules are more common in women than in men. They also tend to run in families. Symptoms of thyroid nodules. Most thyroid nodules don't cause symptoms. For people who do have symptoms, they may have trouble swallowing or breathing or have a feeling of fullness, pain, or pressure in the throat or neck. Some people might notice a lump. Rhizobia are legume root-nodule bacteria. They are soil bacteria that induce the formation of special structures (nodules) on the roots of their host plants. Inside these nodules, the rhizobia fix nitrogen. This means that they convert dinitrogen (the nitrogen gas that makes up 80% of the air you breathe) into ammonia. Ammonia is toxic, s Although some thyroid nodules may be discovered at physical examination, many are incidental findings of other imaging studies, such as CT and MRI of the neck or chest and carotid ultrasound imaging. FNA of thyroid nodules has replaced blind surgical excision as the procedure of choice in the diagnosis of thyroid nodules What are thyroid nodules? The thyroid gland is located in the lower front of the neck, below the voicebox (larynx) and above the collarbones. A thyroid nodule is a lump in or on the thyroid gland.
