Lacrimal Gland Choristoma in the Setting of Acute on Chronic Sinusitis: A Rare Case Report

Abstract

Objective: The current study presents the first reported case of an incidental lacrimal gland choristoma in the setting of acute on chronic sinusitis with presumed orbital involvement. Background: Choristomas are benign masses comprised of histologically normal tissue located at abnormal sites likely due to aberrant implantation of embryonic cells. Only a handful of cases of lacrimal gland choristomas have been reported in the literature. Clinical Case: A 12-year-old boy presents with orbital proptosis in the context of acute on chronic sinusitis. Attempted intra-operative drainage incidentally revealed an orbital tumor. Conclusion: In the context of presumed orbital complications of acute on chronic sinusitis, orbital tumors must be considered. All sinus cases involving the orbit require an ophthalmology consult to ensure appropriate diagnostic and surgical management for these patients.
