Pretibial myxedema (myxoedema in British English, also known as Graves' dermopathy, thyroid dermopathy,[1] Jadassohn-Dösseker disease or myxoedema tuberosum) is an infiltrative dermopathy, resulting as a rare complication of Graves' disease,[2] with an incidence rate of about 1–5%.
Signs and symptoms
Pretibial myxedema is almost always preceded by the ocular signs found in Graves' disease.[3] It usually presents itself as a waxy, discolored induration of the

Risk factors
There are suggestions in the medical literature that treatment with radioactive iodine for Graves' hyperthyroidism may be a trigger for pretibial myxedema[5] which would be consistent with radioiodine ablation causing or aggravating ophthalmopathy, a condition which commonly occurs with pretibial myxedema and is believed to have common underlying features.[6]
Other known triggers for ophthalmopathy include thyroid hormone imbalance, and tobacco smoking, but there has been little research attempting to confirm these are also risk factors for pretibial myxedema.

Management
Many cases of pretibial myxedema, particularly cases that are mild, can be managed without specific pharmacologic treatment; approximately 50% of mild cases achieve complete remission without treatment after several years. When pharmacologic treatment is considered, topical, locally injected, or systemic corticosteroids may be used.[7]
