In radiology, the thumbprint sign, or thumbprinting, is a radiologic sign found on a radiograph that suggests the diagnosis of either epiglottitis or intestinal ischemia.. In a lateral C-spine radiograph, the sign is caused by a thickened free edge of the epiglottis, which causes it to appear more radiopaque than normal, resembling the distal thumb.
Traditional serrated adenoma seen under microscopy with H&E stain, showing serrated crypts. SPS may occur with one of two phenotypes: distal or proximal. [6] The distal phenotype may demonstrate numerous small polyps in the distal colon and rectum, whereas the proximal phenotype may be characterized by relatively fewer, but larger polyps in the proximal colon (cecum, ascending colon, etc.). [6]
The serrated polyposis syndrome (SPS) is a relatively rare condition characterized by multiple and/or large serrated polyps of the colon. Serrated polyps include SSLs, hyperplastic polyps, and traditional serrated adenomas. Diagnosis of this disease is made by the fulfillment of any of the World Health Organization's (WHO) clinical criteria. [4]
A 2023 study found that consuming ultraprocessed foods increased the risk of developing precursors to colon cancer, such as polyps, tumors and lesions. Examples of ultraprocessed foods include ...
Woman going into the bathroom. Colon cancer is relatively common in the U.S. The American Cancer Society (ACS) estimates that it's the third-most common cancer (excluding skin) and more than ...
Neoplastic polyps of the bowel are often benign hence called adenomas. An adenoma is a tumor of glandular tissue, that has not (yet) gained the properties of cancer. [citation needed] The common adenomas of the colon (colorectal adenoma) are the tubular, tubulovillous, villous, and sessile serrated (SSA). [18]
The American Cancer Society recommends starting screening when you turn 45, if you’re at average risk for developing colon cancer; earlier, if you have a family history of the disease or other ...
Juvenile polyps are a type of polyp found in the colon. While juvenile polyps are typically found in children, they may be found in people of any age. Juvenile polyps are a type of hamartomatous polyps, which consist of a disorganized mass of tissue. They occur in about two percent of children. [2]
