- to review the most common soft tissue masses of the foot and hand, focusing on those lesions, that based,on their behavior and location, the radiologist can suggest a specific type of tumor. - to describe the role of imaging techniques in the diagnostic approach .

The differential diagnosis of soft tissue lesions of the foot and hand can be narrowed significantly with the aid of imaging ( X-ray, sonography, CT and MRI). Radiographs are critical in determining the presence /absence of mineralization and setting whether soft tissue mineralization are chondral or ossific in nature and to evaluate cortical involvement versus isolated soft tissue lesion. The ultrasound seems well suited for screening soft tissue masses, allowing us to differentiate cystic from solid nature.In non cystic lesion the location and signal characteristics can suggest the diagnosis of some specific pathologies such as Morton's neuroma, giant cell tumor of tendon sheath, and plantar fibromatosis.Equally, and based on the presence or absence of mineralization, lesion density/ signal intensity, and enhancement pattern Synovial based lesions of the foot and hand can be suggested.Finally, knowledge of the incidence of specific neoplasms of the foot and hand based on patient age aids radiologists in providing a limited differential diagnosis.
