Large excisions or Mohs' micrographic surgery (MMS) are often the suggested treatments for non-melanoma skin cancers (NMSCs) of the external ear. This five-year follow-up attempts to evaluate whether curettage-cryosurgery could be an alternative therapy for selected auricular NMSCs. One hundred auricular NMSCs, selected at a skin tumour clinic, were treated by a thorough curettage, with different-sized curettes, followed by cryosurgery in a double freeze-thaw cycle. Seventy-seven basal cell carcinomas (BCCs), 13 squamous cell carcinomas (SCCs), six SCCs in situ, and four basosquamous carcinomas were included. The mean diameter of the tumours was 18 mm (range 5-70). Morphoeiform BCCs, recurrent BCCs with fibrotic component, and most of the SCCs were selected for MMS. Seventy-one patients with 81 tumours were followed-up for at least five years with only one recurrence. Nineteen patients with 19 tumours, followed-up for two to four years, died from other causes with no sign of recurrence at their last visit. Patients followed-up for less than two years were excluded. No major problems were registered after treatment. The cosmetic result was good or acceptable in most patients. In carefully selected patients a thorough curettage followed by freezing with liquid nitrogen in a double freeze-thaw cycle could be a safe and inexpensive therapy even for large NMSCs of the external ear.
