Location: Deep-seated, proximal extremities and trunk. Clinical: Enlarging painless soft tissue mass. Imaging: Although imaging characteristics are nonspecific, most tumors appear lobulated, and highly myxoid tumors have a homogeneous high…
Location: Deep-seated, lower limb within the muscle, thigh. Clinical: Globose or multinodular mass, slowly increasing, and painless. Tumor may be large, present from many years, and richly vascularized with pulsation…
Localization: ES is as frequent in flat and short bones as it is in long bones. Among the appendicular skeleton, the most common localization is the femur, followed by the…
Location: In association with major nerve trunks: sciatic nerve, brachial plexus, sacral plexus. Gluteal region and pelvis, thigh region, shoulder region, and axilla are the most frequent sites. Clinical: Rapidly…
Location: R. of the limbs constitutes 15 % of all tumors. Type (a): Head, neck, genitourinary tract (botryoid variety), retroperitoneum. Type (b): Limbs (forearm, hand, foot). Type (c): Limbs (prevails…
Location: Type (a): retroperitoneum. Commonly involves kidney, pancreas, and vertebral body for direct extension. Type (b): in the limbs, from piliferous areas. Quite small, less than 2 cm. subcutaneous tumors…
Imaging: The plain x-ray is usually diagnostic. Typically, OS starts intramedullary but breaches the cortex and expands in the soft tissues. It is usually a combination of radiolucency and radiodensity,…
Location: >50 % knee, then elbow, shoulder, wrist, hip, and ankle. Extra-articular form in the fingers. Clinical: Pain, limited joint motion, and sensation of joint crackling. Rare blocking and joint…
Localization: The most common locations of metastatic carcinoma are the spine, pelvis, femur, ribs, and skull. Metastases may affect any bone but are rare distal to elbow and knee. Clinical:…
Localization: About half of the cases are localized in the skeleton of the trunk and skull (particularly jaws). The other half occurs in the long bones (metaphysis or diaphysis). Not…
