Fibrosarcoma:
|
a. A malignant, collagenous, metastatic tumor that can occur at any age and
which is uncommon in the foot b. They may be deep or intradermal c. They also may be well differentiated or poorly differentiated d. They may show a histologic "herringbone" pattern of cellular arrangement |
|
Chondrosarcoma:
|
a. Is a malignant, potentially metastatic cartilage tumor that may show
myxoid and/or osseous elements b. It Is the third most common malignant bone tumor c. Most frequently seen between the ages of 40 & 60 Patients demonstrate a painful limp and a mass may be palpable |
|
Unicameral (Simple) Bone Cyst:
|
Generally are asymptomatic lytic lesions, that are thought to be
interosseous synovial cysts as a result of entrapment if synovium during bone development Most cases arise in males over-20 years old Pain may suggest a fracture of the wall, and a "fallen fragment sign" represents a fracture chip within the cyst |
|
Ewing's Sarcoma
|
Is a very malignant, small-cell bone tumor
On x-rays, nonspecific "onionskin" changes and lytic lesions may be present, and affected areas may be swollen, painful, and tender It is the fourth most common malignant bone tumor, and is seen most frequently under the age of 20 years |
|
Most Common Benign Primary Bone Tumor:
|
#1 osteochondroma (bone spur, subungual exostosis, and other variants)
|
|
"Onionskin" Periosteal Reactivity Can Be Seen In:
|
#1 osteomyelitis (especially Garre sclerosing type
