Intra-Areolar Polythelia with a Partly Doubled Areola without Any Other Malformation of the Breast.

The article presents an unusual case of intra-areolar polythelia, a rare condition where one or more supernumerary nipples are located within the areoloa. Researchers believe that the condition is caused by intrauterine division of the developing breast or nipple. In this unusual case, the division affected not only the nipple but also the areola. The congenital abnormality must be differentiated from the supernumerary nipples or polythelia which is relatively common.
