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.
