Unexpected positron emission tomography/computed tomography uptake in benign dermal naevus.

Positron emission tomography/computed tomography (PET/CT) imaging modalities are commonly utilised for investigation of known or suspected neoplastic disease. A variety of 18-F-fluorodeoxyglucose (FDG) positive cutaneous lesions have been described in the literature, including both malignant lesions and benign inflammatory conditions. We report a case of PET/CT-positive dermal naevus.
