Images of Hyperthyroidism: Hyperthyroid Hyperpigmentation

Hyperpigmentation is seen on the cheeks and eyelids of a 36-year-old woman.

She became hyperthyroid at age 19 years, with accompanying exophthalmos and hyperpigmentation, following the birth of her first child.

Thyroidectomy was carried out at that time, and the patient has been receiving thyroid replacement therapy ever since.

The hyperpigmentation, an uncommon accompaniment of hyperthyroidism, has persisted.
