Polymorphous low-grade adenocarcinoma located in the maxillary sinus

Area of Science:

• Oncology
• Pathology

Background:

• Polymorphous low-grade adenocarcinoma (PLGA) is a malignant epithelial tumor.
• It typically presents with a low metastatic rate and infiltrative growth.
• The palate is the most common site for PLGA.

Observation:

• This report details an uncommon case of PLGA originating in the maxillary sinus.
• Paranasal sinuses are rare locations for this type of adenocarcinoma.
• The maxillary sinus is an exceptionally rare site for PLGA.

Findings:

• The study presents a case of polymorphous low-grade adenocarcinoma in the maxillary sinus.
• This highlights the potential for PLGA to occur in rare head and neck locations.
• Despite its low-grade nature, PLGA can progress over time.

Implications:

• PLGA should be included in the differential diagnosis for tumors in rare head and neck sites.
• Awareness of PLGA in uncommon locations like the maxillary sinus is crucial for accurate diagnosis.
• Long-term follow-up may be necessary due to the potential for late progression.
