Myxedema is a rare, cutaneous complication of autoimmune thyroid diseases that most often affects the anterior shins. Herein, we report a patient with a history of Graves disease and Hashimoto thyroiditis who presented with boggy, alopecic patches associated with scalp pruritus. Punch biopsies from these lesions showed increased interstitial mucin in the reticular dermis, consistent with localized myxedema. This report showcases a rare presentation of localized myxedema of the scalp, highlighting the diverse cutaneous manifestations of autoimmune thyroid diseases.
