Benign ganglion cysts of the digits, typically located at the distal interphalangeal joints or in the proximal nail fold.
They usually occur on the hands, although they uncommonly occur on the toes.
Etiology is uncertain but may involve mucoid degeneration.
Usually asymptomatic and do not require treatment.
Cysts probably arise from mucoid degeneration of connective tissue and that this process, in most cases, involves communication with the adjacent DIP joint and possible coexistence of osteoarthritis.
Osteoarthritis is common at the site of the cysts.
