Abstract
PURPOSE: To determine the causes of lacrimal gland inflammation based on histopathology and systemic evaluation. METHODS: This is a retrospective case series study. From the University of British Columbia Orbit Clinic between January 1976 and December 2008, we reviewed the medical records of 60 patients who presented with inflammatory features of the lacrimal gland (i.e., erythema, edema, or tenderness) in which the diagnoses were not possible clinically and on imaging alone. As was our routine practice, all these patients underwent lacrimal gland biopsy before starting any treatment. RESULTS: The histopathologic findings of the 60 patients showed that 37 (61.7%) had identifiable types of lacrimal inflammation including 10 with Sjogren's syndrome, seven with sarcoidal reaction, six with feature of granulomatosis with polyangiitis (formerly known as Wegener's granulomatosis), five with lymphoma, two with sclerosing inflammation, two with IgG4-related dacryoadenitis, and one patient each with infectious dacryoadenitis, myoepithelial carcinoma, xanthogranuloma, eosinophilic angiocentric fibrosis, and eosinophilic allergic granulomatous nodule. The histopathologic findings of the remaining 23 (38.3%) patients showed nonspecific inflammation of the lacrimal gland. 23 patients (38.3%) had associated systemic diseases. 48 patients (80%) were treated successfully and 10 (16.7%) had recurrence of inflammation. CONCLUSIONS: We recommend that in patients presenting with lacrimal gland inflammation (i.e., erythema, edema, tenderness) in which the specific diagnosis cannot be made clinically and on imaging, biopsy is warranted for accurate diagnosis and appropriate treatment. We found that the majority of these patients (61.7%) had specific histopathology, and 38% had systemic diseases.
