Abstract
A selective policy is proposed for the use of frozen section in suspected melanoma which provides maximal help while minimizing false frozen section diagnosis. It is based on the fact that suspected melanomas fall into two broad groups which present different problems in diagnosis and management. A raised lesion is likely to be a highly malignant melanoma or a lesion of non-naevoid cells. Differentiation is readily made on frozen section and allows immediate radical excision. A flat pigmented lesion is usually of obvious naevoid origin, and the problem is whether early malignant change has occurred. It is better managed by urgent paraffin section to avoid sampling error. Frozen section has a place in the management of a single doubtful node in a patient being managed by a “watch” policy.
