Teratomas contain many cell types such as skin, nerve, brain and thyroid, among others, because they are derived from germ cells. Hamartomas are a group of benign tumors that have relatively normal cellular differentiation but exhibit disorganized tissue organization.Exceptions to the nomenclature rules exist for historical reasons; malignant examples include melanoma (a cancer of pigmented skin cells, or melanocytes) and seminoma (a cancer of male reproductive cells).Benign tumors do not encompass all benign growths. Skin tags, vocal chord polyps, and hyperplastic polyps of the colon are often referred to as benign, but they are overgrowths of normal tissue rather than neoplasms. Treatment
Benign tumors typically need no treatment unless if they cause problems such as seizures, discomfort or cosmetic concerns. Surgery is usually the most effective approach and is used to treat most benign tumors. In some cases, other treatments may be used. Adenomas of the rectum may be treated with sclerotherapy, in which chemicals are used to shrink blood vessels in order to cut off the blood supply. Most benign tumors do not respond to chemotherapy or radiation therapy, although there are exceptions; benign intercranial tumors are sometimes treated with radiation therapy and chemotherapy under certain circumstances. Radiation can also be used to treat hemangiomas in the rectum. Benign skin tumors are usually surgically resected but other treatments such as cryotherapy, curettage, electrodesiccation, laser therapy, dermabrasion, chemical peels and topical medication are used. Name
The word "benign" means "favourable, kind, fortunate, salutary, propitious".
