Usefulness of 18F-FDG PET/CT in recurrent basal cell carcinoma: Report of a case

We analyze the case of a patient with left periorbital infiltrating basal cell carcinoma treated with surgical excision in October 2010. Surgery included orbital exenteration and reconstruction using skin graft and radiotherapy. In May 2013 a MR imaging showed a mass in the left orbital fossa, suggesting a recurrence in the graft. A basal cell carcinoma recurrence with perineural invasion was confirmed in the biopsy. On F-18-FDG PET/CT performed, a hypermetabolic activity was observed in the left periorbital area with extension to surrounding sinus and bones. The use of F-18-FDG PET/CT in patients with advanced basal cell carcinoma has not been fully explored due to the rarity of this entity. This case demonstrates the usefulness of this technique to determine the extent of non-melanocytic recurrent skin tumors, and its value in the staging and treatment control, supporting the incorporation of F-18-FDG PET/CT in the management of advanced basal cell carcinoma.
