Stasis Mucinosis: Insights Into Euthyroid Localized Mucinosis.

Stasis mucinosis and obesity-associated lymphedematous mucinosis (OALM) have been described as 2 discrete diagnostic entities.A morbidly obese African American man in his late 60s presented to the emergency room with a 3-month history of swelling of both lower extremities and secondary changes suggestive of lymphedema and venous dermatitis. On physical examination, the patient had severe edema with multiple raised areas of verruciform skin changes and varicosities, diffuse induration, erythema, and scaling. He also had an open wound in his left hallux. The skin biopsy found mucinosis. A diagnosis of stasis mucinosis was rendered. He had normal thyroid function test laboratory results.The authors suggest stasis mucinosis and OALM represent the spectrum of euthyroid mucin depositional disease in varying clinical settings.
