Nodular pretibial myxedema.
A 30-year-old man with previously diagnosed and treated Graves disease presented for consultation regarding asymptomatic nodules over his anterior tibias. He was euthyroid at the time of presentation. The nodules arose symmetrically beneath the sites of pressure from his military boots. A biopsy specimen showed an accumulation of acid mucopolysaccharides consistent with pretibial myxedema. The patient had recently stopped smoking and chewing tobacco, which are known risk factors for the development of pretibial myxedema. Following diagnostic punch biopsies, the patient experienced a rapid resolution of the nodule on his right leg and a appreciable reduction in size of the nodule on the left leg. Three months later, the nodules are beginning to enlarge once again.
