Summary
This study reports the first documented case of juxtaarticular chondroma in the temporomandibular joint (TMJ) affecting the parotid region. The benign cartilage tumor presented diagnostic challenges, requiring careful surgical consideration.
Area of Science:
- Oral and Maxillofacial Surgery
- Orthopedic Oncology
- Pathology
Background:
- Juxtaarticular chondromas are rare benign tumors originating from mature hyaline cartilage.
- Cartilage tumors of the temporomandibular joint (TMJ) are uncommon, posing diagnostic challenges.
- Distinguishing these tumors from other parotid region masses, such as pleomorphic adenoma, is crucial for appropriate management.
Observation:
- A 54-year-old woman presented with a 3.5 cm right preauricular tumor, developing over 4 years.
- The tumor was asymptomatic initially but later caused temporomandibular joint (TMJ) dysfunction, including pain and clicking.
- Preoperative diagnosis was complicated by the differential possibilities of a parotid pleomorphic adenoma and a TMJ cartilage tumor.
Findings:
- Surgical excision of the tumor was performed while preserving the parotid gland.
- Histopathological examination confirmed the diagnosis of chondroma, consisting solely of chondroid tissue.
- This case represents the first reported instance of juxtaarticular chondroma of the TMJ in the parotid region in English medical literature.
Implications:
- This case highlights the importance of considering rare cartilaginous tumors in the differential diagnosis of parotid region masses.
- Accurate preoperative diagnosis is essential for guiding surgical strategy and ensuring optimal patient outcomes.
- Further literature review is needed to understand the clinical characteristics and diagnostic nuances of juxtaarticular chondromas in this location.
