Supernumerary nipples

Alternative names
Polymastia; Polythelia; Accessory nipples

This condition is the presence of additional nipples.


Supernumerary nipples are a fairly common occurrence, generally unrelated to other conditions or syndromes. They usually occur in a line below the existing nipple and are often not recognized as extra nipples, because they are usually small and not well formed.

Common Causes

  • Variation of normal  
  • Hay-Wells syndrome (very rare)  
  • Ruvalcaba-Myhre syndrome (very rare)

Home Care

Usually no treatment is needed. The extra nipples DO NOT develop into breasts at puberty.

Call your health care provider if

  • You notice supernumerary nipples on your infant.  
  • There are other symptoms present.

What to expect at your health care provider’s office

The medical history will be obtained and a physical examination performed.

Documenting supernumerary nipples usually includes simply noting that the infant had extra nipples (also how many and where on the chest they were located).

After seeing your health care provider:
Most often, this is simply a variation of normal. However, if a disorder was diagnosed related to the extra nipples, you may want to note that diagnosis in your personal medical record.
