A Fourteen-year-old Hypothyroid Adolescent Boy with Preradial and Pretibial Myxedema

Abstract

Localized myxedema is most commonly described in patients with hyperthyroidism, especially Graves’ disease, but rarely may also be present in patients with hypothyroidism. Myxedema generally appears as indurated plaques localized on the shins; it has also been rarely reported in other areas such as the face, shoulders, arms, and abdomen. Here, we report a case of extensive preradial and pretibial myxedema in a 14-year-old boy with hypothyroidism. After starting treatment with thyroxine, there was remarkable improvement within 4 months. Preradial myxedema is a rare presentation with only a few cases reported.
