Study Notes
Characteristics
- Bone-forming tumors are a type of primary bone tumor that produces bone tissue
- Can be benign or malignant
- Classified into two main categories: osteoma and osteosarcoma
Osteoma
- Benign bone tumor
- Most common type of bone-forming tumor
- Typically occurs in the craniofacial bones (e.g. skull, face)
- Slow-growing and asymptomatic
- Treatment usually not necessary, but may be removed for cosmetic reasons
Osteosarcoma
- Malignant bone tumor
- Most common type of primary malignant bone tumor
- Typically occurs in the long bones (e.g. femur, tibia)
- Can occur in any bone, but most common in children and adolescents
- Symptoms include pain, swelling, and limited mobility
- Treatment typically involves surgery, chemotherapy, and radiation therapy
Diagnosis
- Imaging studies (e.g. X-ray, CT, MRI) to visualize the tumor
- Biopsy to confirm diagnosis and determine tumor type
- Staging to determine extent of tumor spread
Treatment
- Benign osteomas: observation or surgical removal
- Osteosarcoma: multimodal treatment including surgery, chemotherapy, and radiation therapy
- Goals of treatment: remove tumor, preserve function, and improve survival rate
