Most small masses that are identified in this way are benign, although smokers, patients already known to have cancer in another organ system, and older patients have an increased risk that a solitary nodule will be a new malignancy or a metastasis from another source. Patient careThe first step in evaluating a solitary lung nodule is to search for prior chest x-ray films. If the nodule can be found on films done many months or years earlier and has not changed in size, shape, or calcification, it is likely to be benign and can be followed conservatively. Newly identified lesions within the lung that were not previously present usually are evaluated with further studies, such as computed tomography of the lungs, sputum studies, or biopsies.  SUBCUTANEOUS NODULESsubcutaneous nodulesSmall, nontender swellings resembling Aschoff's bodies and found over bony prominences in persons with rheumatic fever or rheumatoid arthritis (in rheumatoid arthritis, they are called rheumatoid nodules).

The nodules may be painful. Synonym: surfer's knots See: illustrationthyroid noduleA visible or palpable mass in the thyroid gland, benign about 90% to 95% of the time. A history of radiation to the head or neck increases the likelihood that the lesion will be malignant, as does the appearance of the nodule in the first decades of life. Fine-needle aspiration biopsy is the first and often the definitive diagnostic test. typhoid nodulesNodules characteristic of typhoid fever and found in the liver.typhus nodulesSmall nodules of the skin seen in typhus. They are composed of mononuclear cell infiltration around vessels. nodule A small, solid knot-like lump of tissue occurring anywhere in the body. Nodules in the skin are easily felt. The term implies nothing about the nature of the lump.nodule - any small spherical swelling.
