Irritated seborrhoeic keratosis masquerading as malignancy on 18F-fluorodeoxyglucose positron emission
1Department of Nuclear Medicine and PET-CT, Apollo Gleneagles Hospital, Kolkata, West Bengal, India.
Abstract:
Seborrhoeic keratosis is a common benign skin tumor and can have a variable presentation. Irritated seborrhoeic keratosis can clinically mimic cutaneous malignancy and often warrant biopsy. 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography-computed tomography (PET-CT) can give false-positive results in many cutaneous pathologies. We present an interesting case of irritated seborrhoeic keratosis masquerading as skin cancer, clinically as well as on18F-FDG PET-CT.
