Recurrence of Melanoma

Abstract

When cutaneous melanoma recurrence is suspected, several imaging techniques can be used to confirm or rule out this possibility as well as performing an adequate follow-up of the disease. [(18)F]Fluorodeoxyglucose (FDG)-PET may play an important role in this setting. Ultrasonography and FDG-PET can be useful in the assessment of regional node involvement but sentinel node biopsy is the gold standard. PET/computed tomography is most useful for identifying all metastatic sites before embarking on a metastasectomy of an apparently isolated lesion or for clarifying the nature of a suspicious lesion identified by CT scan.
