Chronic cutaneous ulcer on the ear helix of 80-year-old male was diagnosed with squamoid eccrine ductal carcinoma (SEDC). SEDC is characterized by both atypical squamous and ductal differentiation. SEDC frequently appears on sun-exposed areas. It could show local recurrence despite complete resection. These characteristics demand cautious attention to SEDC.
