Basal Cell Epitheliomas Treated by Mohs Chemosurgery. Presented by Rex A. Amonette, MD, Richard H. Shereff, MD. 

Case 1.—  A 78-year-old black woman had a large (6.5×5.5 cm) basal cell epithelioma in the postauricular sulcus. Infiltrating tumor extended over the posterior surface of the ear and onto the posterolateral area of the scalp. There was no history of trauma or evidence of scar in this area. The epithelioma was surgically removed using Mohs technique. Seven stages of chemosurgery and 72 frozen tissue sections were required to reach a tumor-free plane. The surgical defect healed by spontaneous granulation.

Case 2.—  A 78-year-old white woman had a 1.0×1.0-cm nodule over a 2×2-cm sclerotic area of the right tip of the nose. Biopsy revealed this lesion to be an infiltrating basal cell epithelioma. To remove the entire tumor, a 4.3×3.8-cm surgical defect was created. This required nine stages
