Description:The index finger depicted in this image displayed a mucinous cyst, also known as a digital mucous cyst (DMC), on its dorsal surface at the location of the distal interphalangeal joint (DIP).
DMCs are benign in nature manifesting on the digits of the hands at the DIP or nail fold. Though they usually require no treatment, however, when they are excised, post-excision recurrence is quite common. Their etiology is not certain, but is believed to be due to the degeneration of cutaneous tissues into a mucinous, gelatinous substance.
