We report an unusual case of malignant granular cell tumor (GCT) of the colon incidentally detected by Fluorine-18-Fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) in a 54-year-old female patient with history of pulmonary adenocarcinoma. 18F-FDG-PET/CT showed an area of increased radiopharmaceutical uptake, corresponding to a 3 cm nodule in the caecum. Based on PET/CT findings, the patient underwent endoscopic resection of the colonic lesion. Histology demonstrated the presence of a malignant GCT of the colon.
