Thyroid acropachy is an unusual presentation of autoimmune thyroid disease, (~1% of patients with Graves disease). It can occur in hyperthyroid, euthyroid, hypothyroid, or even post-treatment patients. It is almost always associated with thyroid ophthalmopathy.
The majority of patients are smokers.
Clinically, it presents with soft tissue swelling, finger clubbing and a periosteal reaction of the extremities.
- prominent smooth flowing periosteal reaction affecting the hands and feet. It is usually bilateral and symmetrical involving the tubular bones of hands and feet
- may also be evidence of soft tissue swelling (especially lower limbs)
