Summary
This study details rare appendicular skeleton tumors, adamantinomas and cementomas. Atypical cementoma localizations were identified, emphasizing angiography and en bloc resection for both tumor types.
Area of Science:
- Skeletal oncology
- Odontogenic tumors
- Orthopedic pathology
Background:
- Adamantinomas and cementomas are rare odontogenic tumors affecting the appendicular skeleton.
- Cementifying fibromas are a less common variant of cementomas.
- These tumors require careful diagnostic and therapeutic consideration due to their rarity and potential for atypical presentations.
Purpose of the Study:
- To present verified observations of adamantinomas and cementomas in the appendicular skeleton.
- To highlight typical and atypical presentations, particularly for cementomas.
- To discuss diagnostic imaging and surgical management strategies for these rare bone tumors.
Main Methods:
- Review of eight verified cases: five adamantinomas and three cementomas.
- Analysis of tumor localization, radiographic features, and diagnostic angiography.
- Evaluation of surgical intervention, specifically 'en bloc' resection.
Main Results:
- Adamantinomas presented with typical localization and radiographic findings in all cases.
- One cementoma was found in a typical metaphyseal location of a long bone.
- Two atypical cementoma localizations (diaphyseal tibia, metacarpal) are reported for the first time globally.
- Angiography consistently indicated benign expansive lesions.
Conclusions:
- Angiography is a crucial diagnostic tool for characterizing these benign expansive lesions.
- 'En bloc' resection is the recommended surgical approach for both adamantinomas and cementomas.
- The identification of atypical cementoma localizations expands the understanding of their potential distribution.
