Adenoid cystic carcinoma of the buccal mucosa: A case report and review of the literature

Subglottic Adenoid Cystic Carcinoma Mimicking Bronchial Asthma: A Case Report

Adenoid cystic carcinoma (ACC) is a rare type of tumor that usually originates from minor salivary glands in the oral cavity. ACC of the larynx is even rare. This case study describes a 36-year-old non-smoking male farmer who initially presented with dyspnea and was misdiagnosed with bronchial asthma. Spirometry revealed fixed airway obstruction. Further evaluation revealed a pedunculated mass obstructing the airway, which was diagnosed as ACC by histopathological examination of the biopsy specimen. The patient was treated with radiation therapy, resulting in clinical improvement after six weeks. ACC is highly invasive and slow-growing, with perineural extension and a higher risk of recurrence. Metastasis in the lungs is common. Adequate preoperative staging, including imaging with computed tomography (CT) and magnetic resonance imaging, is important for planning treatment. The role of radiation therapy with concurrent chemotherapy is still under trial.

Adenoid cystic carcinoma of the retromolar pad region: A case report

INTRODUCTION

Adenoid cystic carcinoma (ACC) is one of the most common salivary gland malignancies, mostly occurs in the major and minor salivary glands in the oral and maxillofacial region. The development of ACC in the retromolar pad is extremely rare, which limits establishing proper diagnosis and management.

PRESENTATION OF CASE

A patient described a 2-month history of finding a mass behind the lower left posterior teeth. Based on the physical examination and radiographic findings, we got an initial impression of a benign mucocele, the nature of which was to be investigated further. Pathological examination of the resected tissue resulted in a diagnosis of ACC. Follow-up visits showed no recurrence during the subsequent 54 months.

DISCUSSION

In cases with an uncertain diagnosis based on medical history, clinical features and imaging examinations, it is important to proceed carefully with the possibility of a tumor in mind.

CONCLUSION

ACC in the retromolar pad is rare and can be easily misdiagnosed. Clinical, radiographic, and pathological evidence confirm a definitive diagnosis. Long-term follow-up is important for the full analysis of ACC treatment.

Adenoid cystic carcinoma of buccal mucosa: A report of two rare cases and review of literature

In the oral cavity, adenoid cystic carcinomas of the buccal mucosa are extremely rare. Minor salivary grand adenoid cystic carcinoma should receive aggressive treatment to achieve negative surgical margins to inhibit recurrence.

Adenoid cystic carcinoma of alveolar mucosa: A rare case report

Adenoid cystic carcinomas are rare epithelial malignancies of salivary glands that show slow growth and local invasion with recurrences seen many years after diagnosis. Upto 50% of tumors occur in intraoral minor salivary glands usually in the hard palate. Tumors on the alveolar mucosa are extremely rare. We present a case of adenoid cystic carcinoma on the right alveolar mucosa in a 35 year old female. The case is been presented for its rarity.
