Dear Director:

The report on «Whole body PET/CT imaging metastatic choroidal melanoma»1 is very interesting. Rodríguez-Marco et al concluded that «PET/CT is a sensitive tool for the detection and localization of hepatic and extrahepatic metastatic choroidal melanoma»1. In fact, PET/CT is confirmed for its usefulness in following up choroidal melanoma. Finger et al. noted that «PET/CT imaging may improve upon the conventional methods of screening for detection of metastatic disease in patients initially diagnosed with choroidal melanoma»2. Kurli et al also proposed that «same conclusion» as Rodríguez-Marco et al that PET/CT is «is a sensitive tool for the detection and localization of hepatic and extra-hepatic (particularly osseous) metastatic choroidal melanoma»3. However, the limitation of using PET/CT in melanoma is still observed. As noted by Keu and Iagaru, «early stage evaluation of melanoma» is still the challenge that needs further improvement4. Finally, the use of whole body PET/CT is limited to detect small metastases5. It is suggested to use focused regional PET/CT in those cases suspected for early small metastases5.
