Digital mucous cyst excision using a proximally based skin flap.

Abstract

Mucous cysts of the fingers are benign ganglionic lesions arising generally from the distal interphalangeal joint that are more frequent between the fifth and seventh decades. They are usually asymptomatic; however, in certain cases such as pain or when the overlying skin is excessively attenuated, leading to breakdown and oozing of synovial fluid and potential risk of infection, surgical excision is recommended. In the present article a technique to excise the cyst while preserving its overlying attenuated skin is presented.
