Amyloidosis of the maxillary antrum

Area of Science:

• Otorhinolaryngology
• Pathology
• Oncology

Background:

• Primary amyloidosis is a rare plasma cell dyscrasia characterized by amyloid protein deposition.
• Maxillary sinus involvement is exceptionally uncommon, presenting diagnostic challenges.

Observation:

• A unique case of primary amyloidosis manifesting as a destructive lesion within the maxillary antrum is presented.
• The lesion's destructive nature mimicked other malignant or infectious processes.

Findings:

• Histopathological examination confirmed amyloid deposition as the cause of the destructive lesion.
• Diagnostic workup involved imaging, biopsy, and laboratory tests to establish the diagnosis and rule out other conditions.

Implications:

• This case highlights the importance of considering rare conditions like amyloidosis in the differential diagnosis of destructive sinonasal lesions.
• Understanding current diagnostic and treatment modalities is crucial for managing patients with primary amyloidosis.
