A 22-year-old woman has grown a full-sized extra nipple on the sole of her foot.
The woman told doctors she had had the unusual growth - which is almost two inches wide - all her life, and it had never caused her any pain.
Although one in 50 women and one in 100 men have extra nipples, according to the California-based Dermatology Journal it's the first time one has ever been discovered so far down somebody's body.
Between one and five per cent of the population have the condition, known as supernumerary breast tissue.
Although most of the time extra nipples are found along the milk lines, which run from the genitals to the armpits, they have been discovered on the back, thigh or even the face - but never the feet.


据英国《每日邮报》18日报道：一22岁女子的脚心里长出一个完整的乳头。

该女子告诉医生，自从她出生，这个罕见的将近2英寸大的东西就一直在，而且从来也不会让她感到疼痛。

虽然女性长出多余乳头的几率是1/50，男性是1%。但据加利福尼亚《皮肤学杂志》讲，乳头长在脚心却是迄今为止生长部位最靠下的一例。

大约有由1%到5%的人会出现这种情况，在医学上它被称为"副乳组织"。

虽然一般情况下，多余的乳头会沿着乳线生长，即从外阴到腋窝的部分。曾经就有乳头长在背部、大腿甚至脸部的例子，但是还从没见长在脚上的。
