Syphilitic dactylitis.

Dactylitis or sausage digit is inflammation of an entire digit (a finger or toe),[1] and can be painful.

The word dactyl comes from the Greek word "daktylos" meaning "finger". In its medical term, it refers to both the fingers and the toes.

Associated conditions[edit]

Dactylitis can occur in seronegative arthropathies, such as psoriatic arthritis and ankylosing spondylitis, and in sickle-cell disease as result of a vasoocclusive crisis with bone infarcts, and in infectious conditions including tuberculosis and leprosy. In reactive arthritis, sausage fingers occur due to synovitis.[2]

In sickle-cell disease it is manifested for the first time between 6-9 month old infants.
