The term polythelium is applicable to mammals , in particular to humans . An increase in the number of nipples is recorded with a frequency of up to 1% in women, 2% in men [2] . Often they are mistaken for moles . Additional nipples appear along two vertical lines drawn through the normal nipple and ending in the inguinal region (usually the nipple line roughly coincides with the midclavicular line ). They are classified into eight levels of development, from a simple bundle of hair to a miniature mammary gland capable of secreting milk. Sometimes nipples are found on the forearm or feet [3] .
The term "polythelium" should be distinguished from polymastia - the presence of additional mammary glands .
