[18F]‐Fluorodeoxy‐D‐glucose uptake in prurigo nodules induced by the membranous expression of glucose transporter

Abstract

Positron emission tomography‐computed tomography (PET/CT) is a valuable imaging modality for assessing malignant tumours; however, the aberrant uptake of [¹⁸F]‐fluorodeoxy‐D‐glucose (FDG) is sometimes observed in benign skin lesions such as corns, seborrhoeic keratosis, viral warts, condyloma acuminatum, rhinophymas, and acne vulgaris^1,2. We encountered a case of prurigo nodularis associated with abnormal uptake of FDG and evaluated the expression of the glucose transporter in the lesions. A 55‐year‐old male with a pulmonary metastasis of malignant melanoma received nivolumab. After three years' nivolumab administration, a PET/CT was performed to evaluate the effect of the immunotherapy.
