Dactylitis

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

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.
