Q

Osteoma

Morphology

A

Exophytic (grows out) growths attached to bone surface;

histologically similar to normal bone

21
Q

Osteoid Osteoma

Morphology

A

Cortical tumors, characterized by pain;

hisotlogic pattern consisting of interlacing trabeculae of woven bone

22
Q

Osteoblastoma

Morphology

A

Arise in vertebral transverse and spinous process;

histologically similar to osteoid osteoma

23
Q

Primary osteosarcoma

Morphology

A

Grow outward, lifting periosteroum, and inward to the medullary cavity;
microscopy shows malignant cells forming osteoid;
cartilage also may be present

24
Q

Secondary Osteosarcoma

Morphology

A

Complications of polyostotic Paget disease;

histologically similar to primary osteosarcoma

25
Q

Osteochondroma

Morphology

A

Bony excrescences with a cartilaginous cap;

may be solitary or multiple and hereditary

26
Q

Enchondroma

Morphology

A

Well-circumscribed single tumors resembling normal cartilage;
arise within medullary cavity of bone;
uncommonly multiple and hereditary

27
Q

Chondrosarcoma

Morphology

A

Arise within medullary cavity and erode cortex;

microscopy shows well-differentiated cartilage-like or anaplastic features

28
Q

Giant Cell Tumor

Morphology

A

Lytic lesions that erode cortex;
Microscopy shows osteoclast-like giant cells and round to spindle-shaped mononuclear cells;
Most are benign

29
Q

Ewing Sarcoma

Morphology

A

Arise in medullary cavity;
Microscopy shows sheets of small round cells that contain glycogen;
Aggressive neoplasm
