[Osteogenic tumors of bone]

Area of Science:

• Oncology
• Radiology
• Pathology

Background:

• Osteogenic tumors encompass benign and malignant bone neoplasms producing osteoid or bone.
• Osteosarcoma is the most prevalent malignant bone tumor, particularly in pediatric and young adult populations.

Purpose of the Study:

• To describe osteogenic tumor entities and their characteristic morphological features for accurate diagnosis and differential diagnosis.
• To guide diagnosis based on patient age, history, and tumor location.

Main Methods:

• Selective review of large published patient cohorts.
• Comparison of own and externally published data using widely accepted tumor criteria.

Main Results:

• Plain X-rays and CT scans are fundamental for detecting osseous lesions.
• MRI and scintigraphy aid in evaluating local tumor extension and biopsy planning; MRI alone is insufficient.
• Staging for malignant bone tumors involves a combination of thoracic CT, MRI, scintigraphy, and PET scans.
• Osteosarcoma, Ewing sarcoma, and chondrosarcoma are the most common malignant bone tumors.
• Osteoid osteomas are the most frequent benign bone tumors, characterized by specific pain, location, and age predilection.

Conclusions:

• Diagnosis and treatment of malignant bone tumors are best managed in specialized centers due to significant therapeutic implications.
• Obtaining a second opinion is recommended in uncertain diagnostic cases.
