What is a sausage digit?
It is the inflammation of a whole digit, giving it a diffusely swollen appearance. A sausage-shaped
swelling of a toe or finger (i.e., dactylitis, from the Greek daktulos, finger) can be quite painful. When
unassociated with trauma, it is usually caused by tenosynovitis, and often periostitis as well as arthritis.
It is frequently seen in seronegative arthritis, typically psoriatic, but also sarcoid–related. In psoriasis, it is
often associated with pitting of the fingernails
