A '''supernumerary nipple''', also known as a third nipple or accessory nipple, is an additional nipple that occurs in humans and other animals. This condition is a type of [[polymastia]], which refers to the presence of more than the usual number of nipples or mammary glands. | A '''supernumerary nipple''', also known as a third nipple or accessory nipple, is an additional nipple that occurs in humans and other animals.

A supernumerary nipple, also known as a third nipple or accessory nipple, is an additional nipple that occurs in humans and other animals. This condition is a type of polymastia, which refers to the presence of more than the usual number of nipples or mammary glands.
Epidemiology[edit]
Supernumerary nipples are relatively common, occurring in approximately 1-5% of the population. They are more frequently observed in males than in females. The condition can be hereditary, with a tendency to run in families.
Embryology[edit]
During embryonic development, the mammary ridge or milk line forms along the chest and abdomen. Normally, this ridge regresses except at the site of the primary nipples. However, if parts of the ridge persist, supernumerary nipples can develop along this line.
Clinical Presentation[edit]
Supernumerary nipples can vary in appearance. They may resemble a normal nipple, or they may appear as small, pigmented moles or bumps. These additional nipples are usually located along the milk line, which extends from the armpit to the groin.
Symptoms[edit]
Most supernumerary nipples are asymptomatic and do not cause any health problems. However, in some cases, they may become tender or swollen, especially during hormonal changes such as puberty or pregnancy.
Diagnosis[edit]
Diagnosis of a supernumerary nipple is typically made through physical examination. In some cases, imaging studies such as ultrasound or mammography may be used to differentiate a supernumerary nipple from other skin lesions.
Treatment[edit]
Treatment is usually not necessary unless the supernumerary nipple causes discomfort or psychological distress. In such cases, surgical removal can be performed. The procedure is generally simple and performed on an outpatient basis.
Associated Conditions[edit]
While supernumerary nipples are usually benign, they have been associated with certain syndromes and conditions, such as:
Prognosis[edit]
The prognosis for individuals with a supernumerary nipple is excellent. The condition does not affect overall health or life expectancy.
