What is a hamartoma of the skin?

Abstract. Hamartomas are benign lesions composed of aberrant disorganized growth of mature tissues. Choristomas are similar, except that they are composed of tissues not normally found at the anatomic site in which the lesion is arising. A wide range of hamartomas and choristomas can arise in the skin and soft tissue.

Is hamartoma a cancer?

A hamartoma is a benign tumor that may occur in the lungs, heart, skin, brain, breast, or other regions. 1 They are made up of abnormal but not cancerous cells similar to the cells that make up the tissue where they originate.

Are hamartomas benign?

A hamartoma (from Greek hamartia, meaning “fault, defect,” and -oma, denoting a tumor or neoplasm) is a benign (noncancerous) tumorlike malformation made up of an abnormal mixture of cells and tissues found in areas of the body where growth occurs.

What causes hamartoma?

Hamartomas result from the abnormal formation of normal tissue and sometimes occur sporadically and a few times as a part of a syndrome. Hamartoma is most likely due to a developmental error and may appear in several sites. It grows at the same rate as of the original tissue.

How fast do hamartomas grow?

The nodular shadow increased in size from 12 × 15 mm to 15 × 20 mm within five months. The calculated tumor doubling time (TDT) in our case was approximately 132.2 days. A malignant tumor was strongly suspected based on the rapid growth, and tumorectomy was thus performed.

Is hamartoma a mixed tumor?

Is hamartoma congenital?

Congenital smooth muscle hamartoma is a congenital skin lesion characterized by proliferation of bundles of smooth muscle within the reticular dermis.

What is hamartoma polyp?

Hamartomatous polyps are composed of the normal cellular elements of the gastrointestinal tract, but have a markedly distorted architecture. The hamartomatous polyposis syndromes are a heterogeneous group of disorders that are inherited in an autosomal-dominant manner.

What is smooth muscle hamartoma?

Smooth muscle hamartoma (SMH) is a proliferative disorder of cells originating from muscle cells. It is a benign tumoral mass that usually presents as a single congenital skin-colored and hypertrichotic plaque involving the trunk and extremities. Multiple SMHs have rarely been reported in the literature.

What happens if you have a hamartoma on your face?

If they occur near an airway, they may cause an obstruction resulting in pneumonia and bronchiectasis. Skin: Hamartomas may occur anywhere on the skin, but are especially common on the face, lips, and neck. 8 Heart: As the most common heart tumor in children, hamartomas can cause symptoms of heart failure. 9

What is a hamartoma?

A hamartoma is a noncancerous tumor made of an abnormal mixture of normal tissues and cells from the area in which it grows. Hamartomas can grow on any part of the body, including the neck, face, and head. In some cases, hamartomas grow internally in places such as the heart, brain, and lungs.

What is basaloid follicular hamartoma?

Basaloid follicular hamartoma is a rare, harmless hair follicle tumour that occurs on the face and scalp, and occasionally, the trunk. It is characterised histologically by an overgrowth of branching cords and strands of basaloid cells. It is very important to distinguish basaloid follicular hamartoma lesions from skin cancer.

How can I get rid of a hamartoma on my forehead?

Be sure to discuss your options with your doctor. A less invasive option, specifically for hypothalamic hamartoma growths, is gamma knife radiosurgery. This procedure uses multiple radiation beams to destroy the tumor cells. The concentrated beams will shrink the hamartoma growths.
