Hamartomas are benign tumor-like growths that occur when an abnormal amount of normal cells builds up on healthy tissue. They have limited growth potential and can shrink or disappear over time. There are different types of hamartomas, including hemangiomas, pulmonary hamartomas, and hypothalamic hamartomas. A pulmonary hamartoma is a benign lung growth that accounts for nearly 75% of all benign tumors found in the lungs. Individuals diagnosed with pulmonary hamartoma have an excellent prognosis, but if the growth has any abnormal characteristics, an additional biopsy or removal may be required. A hypothalamic hamartoma is located near the hypothalamus and can cause seizures, behavioral problems, and precocious puberty.
A hamartoma is a benign tumor-like growth. It usually occurs when an abnormal amount of normal cells builds up on healthy tissue. The cells that make up the hamartoma retain their function, unlike the cells that create malignant tumors. They have limited growth potential, so they are not considered cancers by the medical community. In fact, in some cases, a hamartoma can shrink or even disappear over time.
There are many different types of hamartomas; however, it is important to distinguish them from a related form of benign tumor called a choristoma. Choristomas also contain normal tissue, but are typically found in abnormal locations. Hamartomas differ based on their location. For example, hemangiomas, pulmonary hamartomas, and hypothalamic hamartomas are among the most sought-after conditions, each located in a different area of the body.
A hemangioma is where the growth consists of vascular tissue. At birth, the growth can appear quite large. It is usually not treated unless the affected person’s facial structure is threatened. Doctors sometimes worry that if the growth is removed from the vascular tissue there could be uncontrollable and severe bleeding. Thus, the patient may be left with worse deformities than if it decreases in size on its own.
A pulmonary hamartoma or benign lung growth actually accounts for nearly 75% of all benign tumors found in the lungs. Growths are made up of tissue found in the lungs, such as fat, fibrous tissue, and epithelial tissue; however, the growth is generally considered disorganized with little chance of becoming malignant. In general, people with pulmonary hamartomas do not show any symptoms. However, it’s important to diagnose the condition accurately because other cancerous tumors can mimic these benign growths.
Individuals diagnosed with pulmonary hamartoma have an excellent prognosis. In fact, it won’t cause death. However, there are some related concerns that could cause problems. For example, if the individual smokes or if the growth has any abnormal characteristics, an additional biopsy or removal may be required. Furthermore, they are more common in men than in women and usually occur between the ages of 45 and 50.
Hypothalamic hamartoma is located near the hypothalamus, near the base of the brain. Consequently, the removal is extremely complicated. A person with a hypothalamic hamartoma may experience laughing or jellied seizures, behavioral problems, seizures, and precocious puberty. Seizures can be very difficult to control; however, anticonvulsants can prevent them from happening. Research indicates that growth near the hypothalamus can begin as little as seven weeks after conception, while the baby is still in the womb.
