Multiple Cutaneous Focal Mucinoses with Hypothyroidism

Abstract

A 54-year-old woman with myxedema had hundreds of discrete cutaneous mucinous papules, which responded dramatically to appropriate replacement therapy with L-thyroxine. Each lesion both clinically and histologically resembled a cutaneous focal mucinosis (cutaneous myxoma). Multiple cutaneous focal mucinoses are a previously undescribed manifestation of hypothyroidism that can be differentiated from other syndromes that have cutaneous mucinous deposits.
