Hypothyroidism causes several skin changes. This is one of the most common occurring as a slight thickening of the skin aorund the eyes, nose, cheeks, and distal extremities. Rarely, palmoplantar keratoderma may be present.
Biopsy of the skin reveals a subtle increase of mucin within the dermis, usually around hair follicles and the blood vessels. There is no increase in fibroblasts.
