Abstract:
Masses in the parapharyngeal area are rare and often due to infectious phenomena arising from the oral cavity or pharynx which lead to abscess formation. Less frequently, the lesion can be neoplastic. Tumours of the parapharyngeal space are rare, accounting for less than 1% of all head and neck neoplasms. We report the case of a patient who came to our observation for mandibular pain. Multiparametric diagnostic imaging was done thus showing a parapharyngeal mass. An ultrasound guided biopsy was performed by a transcutaneous route with a high median approach at neck level, to characterize the mass in the right tonsillar region. The histological examination reported the final histological diagnosis of sarcomatoid carcinoma.
Insights
Parapharyngeal masses are rare, often infectious but can be neoplastic. This case highlights a rare sarcomatoid carcinoma presenting as a parapharyngeal mass, diagnosed via imaging and biopsy.
Area of Science:
- Oncology
- Head and Neck Surgery
- Diagnostic Imaging
Background:
- Parapharyngeal masses are uncommon, with infections being the most frequent cause.
- Neoplastic lesions of the parapharyngeal space represent less than 1% of head and neck tumors.
- These masses can present with varied symptoms, including pain.
Purpose of the Study:
- To report a rare case of sarcomatoid carcinoma presenting as a parapharyngeal mass.
- To emphasize the importance of diagnostic imaging and biopsy in characterizing such lesions.
- To contribute to the understanding of rare head and neck neoplasms.
Main Methods:
- A patient presented with mandibular pain, leading to the discovery of a parapharyngeal mass.
- Multiparametric diagnostic imaging was utilized to evaluate the mass.
- An ultrasound-guided biopsy via a transcutaneous approach was performed for histological analysis.
Main Results:
- Diagnostic imaging revealed a parapharyngeal mass in the right tonsillar region.
- Histological examination confirmed the diagnosis of sarcomatoid carcinoma.
- The mass was successfully characterized through the performed biopsy.
Conclusions:
- Sarcomatoid carcinoma is a rare diagnosis for parapharyngeal masses.
- Multimodality imaging and guided biopsy are crucial for accurate diagnosis.
- Early and precise diagnosis is essential for appropriate management of rare head and neck neoplasms.
