Cancer of the periauricular region.
Cutaneous carcinoma of the auricular and periauricular region can be diagnosed early and often can be cured; however, many of these tumors become difficult to treat because of local spread and regional metastasis. Those tumors that are not treated early often require more aggressive treatment with ear canal resection, partial temporal bone resection, or even parotidectomy and radiation therapy. Mohs histographic surgery combined with conventional excision affords the best marginal control for local eradication of these tumors.
