History

A 45-year-old female, who is known to have a connective tissue disease, presented to the clinic complaining of pain in all fingers. On physical examination, fingertips were tender and appeared bulbous. There is shortening of all fingers.

Q1: What are your findings?

Q2: What are the possible causes?

Q3: Can it be in a single digit?

Findings

The AP [Figure - 1]a AP and Oblique [Figure - 1]b views of the hands demonstrate bilateral terminal tuft resorption.

There is no evidence of erosions seen. No evidence of soft-tissue calcification. No joint destruction is seen.

Diagnosis

Acroosteolysis.

Pearls and Discussion

Acroosteolysis is tuft resorption or resorption of the distal phalanges. It can also affect the shaft of the distal phalanx.

When the terminal tuft is resorbed, the differential is usually of scleroderma, psoriasis, thermal injury (if it is cold then it is frostbite, if it is from heat then it is from burns or electricity), dermatomyositis can cause it, as can reactive arthritis and juvenile chronic arthritis.

If it is the mid shaft that is reabsorbed, then toxicity from polyvinyl chloride exposure, hyperparathyroidism (look for brown tumors in that case) or the rare Hajdu–Cheney syndrome.

Single-digit reabsorption can occur in trauma cases, glomus tumor of the digit, or epidermoid inclusion cyst.

Metastasis from bronchogenic cancer can give the cookie bite appearance of the terminal tuft. Osteomyelitis can cause tuft resorption as well.
