Unusual finding of benign Abrikossoff tumor by F-18 FDG-PET mimicking melanoma recurrence

Granular cell tumor of Abrikossoff is a rare neoplasm that may occur in a wide variety of cutaneous and visceral sites. Granular cell tumor generally shows benign behavior. However, malignant outcome with metastatic spread has also been reported. Until now, no data were available on the most useful imaging approach for diagnosis and staging. We present a case of F-18 fluorodeoxyglucose positron emission tomography in Abrikossoff tumor, suggesting that F-18 fluorodeoxyglucose positron emission tomography may have a potential role in the management of this neoplasm.
