Case ReportsUncommon isolated distant subcutaneous tissue and skeletal muscle metastasis from oesophageal cancer diagnosed by PET/CT (18)F-FDG.
Distant soft-tissue metastases (subcutaneous tissues and skeletal muscle) are extremely rare, particularly in oesophageal carcinoma. The case is described of a patient who was treated for oesophageal adenocarcinoma 2.5 years previously. ⋯ Restaging PET/CT (18)F-FDG study was performed 2 year later, demonstrating foci of increased uptake within several muscles as isolated distant haematogenous spread of metastases, histopathologically confirmed. As most of soft-tissue metastases are asymptomatic, the physicians should recommend a histopathological study of focal FDG uptake at subcutaneous tissues and/or skeletal muscles, because they may be the first sign of disease spread, so therapeutic management of these patients could be changed.

Comparative StudyDetection of bone metastases in breast cancer patients in the PET/CT era: Do we still need the bone scan?
To examine the value of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) for the detection of bone metastasis in breast cancer patients and assess whether whole body bone scan (BS) with (99m)Tc-methylene diphosphonate provides any additional information. ⋯ Our findings suggest that FDG-PET/CT is superior to BS with or without SPECT/CT.
