Nodular lichen myxedematosus during childhood: a case report.

Nodular lichen myxedematosus (LM) is a rare disease and is one of the five subtypes of localized LM. It is distinctly characterized by multiple nodules on the trunk and limbs with or without papular lesions. A healthy 6-year-old boy presented with complaints of "knots" on his right chest, upper limb, and thigh for 4 months. To our knowledge this is the first case of nodular LM reported in a child.
