A supernumerary digit is a congenital growth at the base of the 5th finger that represents a rudimentary (and extra) digit. It is also known as rudimentary supernumerary digit or rudimentary polydactyly.


A congenital, flesh-colored papule or pedunculated papulonodule on the base of the 5th finger is typical. At times it may be as large as a (sixth) digit.


Simple surgical excision is appropriate.
