Surgical excision of pseudotumorous pretibial myxedema.

Pretibial myxedema is a well-known clinical feature of autoimmune thyroid malfunction and is classically associated with Graves' disease. Its clinical course is frequently not related to the clinical control of the underlying thyroid disease. Treatment is primarily medical, consisting of oral and topical corticosteroids. We present a case of successful local excision of a pseudotumorous manifestation at the dorsum of the foot recalcitrant to multimodal medical and dermatological therapy.
