Familial supernumerary nipples (also known as polythelia) is a rare congenital condition in which a person has extra nipples along the milk line, which is the line running from the armpit to the groin. These extra nipples may range from a small patch of skin to a fully developed nipple with the same characteristics as a normal nipple.

The most common symptom of Familial supernumerary nipples is the presence of extra nipples along the milk line, which is the line running from the armpit to the groin. These extra nipples may range in size from a small bump to a fully developed nipple with areola and may even produce milk. Other symptoms may include extra nipples on the chest, abdomen, back, or buttocks.

The exact cause of familial supernumerary nipples is unknown. However, it is believed to be a genetic disorder that is passed down through families. It is thought to be caused by a mutation in the gene that controls the development of the mammary glands during fetal development.

The treatment for Familial supernumerary nipples is typically cosmetic surgery. This surgery is usually done on an outpatient basis and involves removing the extra nipples and any associated tissue. In some cases, the nipples may be reduced in size or reshaped to make them less noticeable. In more severe cases, the nipples may be completely removed.

3. Age: Most cases are seen in children and adolescents

There is no cure for familial supernumerary nipples, but they can be removed surgically if desired. Medications are not typically used to treat this condition.
