What is parathyroid adenoma? Parathyroid Adenoma. Your parathyroid glands, four very small glands located near or at the back of the thyroid gland, produce parathyroid hormone (PTH). This hormone helps control the amount of calcium and phosphorus in your blood. A parathyroid adenoma is a benign tumor on one of these glands. This causes your calcium and phosphorus balance to be disrupted, as the affected gland releases more PTH than it should. This condition is called hyperparathyroidism.

What are enlarged adenoids? Adenoids are small tissues located at the back of the throat. They are similar to the tonsils, and located right above them. Both adenoids and tonsils are part of the immune system. Adenoids are present at birth, and they grow until a child is between the ages of 3 and 5.Normally, they begin to shrink after around age 7. They shrink considerably in adulthood.1  The adenoids can cause problems if they become enlarged.oth adenoids and tonsils are part of the immune system.

The adenomatous polyp is considered pre-malignant, i.e., likely to develop into colon cancer. The other types of polyps that can occur in the colon are the hyperplastic and inflammatory polyps.They are unlikely to develop into colorectal cancer. About 5% of people aged 60 will have at least one adenomatous polyp of 1 cm diameter or greater. 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 no stalk is present, it is said to be sessile. Polyps are commonly found in the colon, stomach, nose, sinus(es) , urinary bladder and uterus.

Osteoma An osteoma is a new piece of bone usually growing on another piece of bone, typically the skull. It is a benign tumor. When the bone tumor grows on other bone it is known as “homoplastic osteoma”; when it grows on other tissue it is called “heteroplastic osteoma”. Osteoma represents the most common benign neoplasm of the nose and paranasal sinuses. The cause of osteomata is uncertain, but commonly accepted theories propose embryologic, traumatic, or infectious causes.

Adenoma An adenoma is a benign tumor of epithelial tissue with glandular origin, glandular characteristics, or both. Adenomas can grow from many glandular organs, including the adrenal glands, pituitary gland, thyroid, prostate, and others. Some adenomas grow from epithelial tissue in nonglandular areas but express glandular tissue structure. Although adenomas are benign, over time they may transform to become malignant, at which point they are called adenocarcinomas. Most adenomas do not transform. But
