TARGET AUDIENCE: This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care. LEARNING OBJECTIVES/OUTCOMES: After participating in this educational activity, the participant will: 1. Identify the population most often affected by COVID toes. 2. Select the assessments that help differentiate the various conditions that cause chilblains-like lesions. 3. Choose appropriate treatment options for the various conditions that cause chilblains-like lesions.

These differentials include "COVID toes, " Raynaud phenomenon, acrocyanosis, critical limb ischemia, thromboangiitis obliterans, chilblains associated with lupus erythematosus, and idiopathic chilblains.
