Basal cell adenoma in maxillary sinus: unusual presentation

Area of Science:

• Otorhinolaryngology
• Oral and Maxillofacial Surgery
• Pathology

Background:

• Basal cell adenoma (BCA) is a benign salivary gland neoplasm.
• Minor salivary glands are common sites for various tumors, but typically not in the maxillary sinus.
• The maxillary sinus is an unusual location for salivary gland tumors.

Observation:

• A case of basal cell adenoma originating from a minor salivary gland is presented.
• The tumor was located within the maxillary sinus.
• This represents an extremely infrequent anatomical site for this type of neoplasm.

Findings:

• Histopathological examination confirmed the diagnosis of basal cell adenoma.
• The tumor's presence in the maxillary sinus is highly unusual.
• No similar reported cases were found in the existing literature.

Implications:

• Highlights the importance of considering rare diagnoses in challenging anatomical locations.
• May prompt further investigation into the potential for salivary gland neoplasms in the sinonasal tract.
• Contributes to the limited case data on basal cell adenomas in atypical sites.
