Thyroid acropachy.

Thyroid acropachy (TA) developed in a 48-year-old man at least six years prior to clinically evident and symptomatic hyperthyroidism. The TA prompted a clinical workup for acromegaly on two occasions, with negative results. It usually develops after diagnosis or treatment of hyperthyroidism and usually occurs in conjunction with exophthalmos. In our patient, TA preceded the diagnosis and treatment of hyperthyroidism and was not associated with exophthalmos.
