Although usually presenting on the milk line, pseudomamma can appear as far away as the foot

Polythelia refers to the presence of an additional nipple alone while polymastia denotes the much rarer presence of additional mammary glands. Although usually presenting on the milk line, pseudomamma can appear as far away as the foot.

A third nipple (also called supernumerary nipples, in the case of multiple nipples) is a condition in which you have one or more extra nipples on your body. This is in addition to the two typical nipples on the breasts. The third nipple, or the presence of multiple nipples, is also known as polymastia or polythelia.

#Types

Supernumerary nipples can fall into several different categories depending on their size, shape, and tissue makeup:

《Category One (polymastia): The extra nipple has an areola around it (the soft, circular tissue around a nipple) and typical breast tissue underneath, which means that a full breast has developed.

《Category Two: The extra nipple has breast tissue underneath but no areola is present.

《Category Three: The extra nipple area has breast tissue underneath but no nipple is present.

《Category Four: The extra nipple has breast tissue underneath but no nipple or areola is present.

《Category Five (pseudomamma): The extra nipple has an areola around it but only has fat tissue underneath rather than breast tissue.

《Category Six (polythelia): The extra nipple appears by itself with no areola or breast tissue underneath.
