Chronic Granulomatous Dacryoadenitis Associated With Pleomorphic Adenoma

Area of Science:

• Ophthalmology
• Pathology
• Oncology

Background:

• Pleomorphic adenomas are common benign tumors of salivary glands.
• Chronic granulomatous inflammation is a rare finding with salivary gland tumors.
• This combination has not been previously reported in lacrimal gland adenomas.

Purpose of the Study:

• To describe the clinical, imaging, and histopathological features of lacrimal gland adenomas associated with granulomatous inflammation.
• To investigate this rare co-occurrence in the lacrimal gland.

Main Methods:

• Case series review of four patients.
• Analysis of clinical presentation, imaging findings (e.g., CT, MRI).
• Histopathological examination of surgical specimens.

Main Results:

• Four patients (3 female, ages 39-53) presented with lacrimal gland adenomas and concurrent granulomatous inflammation.
• One patient was asymptomatic; three had symptoms lasting years to decades.
• The proposed etiology is an inflammatory reaction to leaked glandular secretions.

Conclusions:

• Chronic granulomatous inflammation can occur with lacrimal gland adenomas.
• This phenomenon may result from an inflammatory response to ductal secretions.
• Further research is needed to confirm the exact mechanism.
