Discrete papular lichen myxedematosus, a subtype of localized papular lichen myxedematosus, is an idiopathic cutaneous mucinosis. It typically presents symmetrically, involving the trunk and extremities. We report on an unusual case of discrete papular lichen myxedematosus with a segmental presentation.
