A polyp is an abnormal growth of tissue projecting from a mucous membrane. If it is attached to the surface by a narrow elongated stalk, it is said to be pedunculated; if it is attached without a stalk, it is said to be sessile. Polyps are commonly found in the colon, stomach, nose, ear, sinus(es), urinary bladder, and uterus.
A solitary pulmonary nodule (SPN) or coin lesion, [1] is a mass in the lung smaller than three centimeters in diameter. A pulmonary micronodule has a diameter of less than three millimetres. [2] There may also be multiple nodules. One or more lung nodules can be an incidental finding found in up to 0.2% of chest X-rays [3] and around 1% of CT ...
Up to 20% of patients show scarring, polyps or vascular changes of the vocal folds following surgery. [7] In severe cases, these resulting symptoms may require further surgery. The patient must always be aware of the impact and potential complications of surgery on their voice, especially if the voice is heavily used occupationally.
Nodules in skin include dermatofibroma [5] and pyogenic granuloma. [6] Nodules may form on tendons and muscles in response to injury, [7] and are frequently found on vocal cords. [8] They may occur in organs such as the lung, [9] or thyroid, [10] or be a sign in other medical conditions such as rheumatoid arthritis. [11]
In the photo, an apparent field defect in this segment of a colon has generated four polyps (labeled with the size of the polyps, 6mm, 5mm, and two of 3mm, and a cancer about 3 cm across in its longest dimension). These neoplasms are also indicated, in the diagram below the photo, by 4 small tan circles (polyps) and a larger red area (cancer).
But this noninvasive imaging tool is also used to diagnose other health issues for people who get their periods — like misplaced IUD's, polyps and ovarian cysts. Video Transcript NADYA OKAMOTO ...
Vocal fold nodules are thought to be the result of vocal fold tissue trauma caused by excessive mechanical stress. [1] [2] [5] During phonation, the vocal folds undergo many forms of mechanical stress. One example of such stress is the impact stress caused by the collision between the left and right vocal fold surfaces during vibration. [2]
Vocal fold lesions such as a vocal fold nodule or other changes in the vocal fold mucosa can lead to increased tension in the larynx and cause dysphonia. [2] Larynogopharyngeal reflux, a process that is similar to GERD, can bring stomach acid into the larynx. This can provoke the larynx to tense to prevent the aspiration of the acid. [3]
