Clinicopathologic Findings From Lacrimal Sac Biopsy Specimens Obtained During Dacryocystorhinostomy

Abstract

Nongranulomatous inflammation consistent with chronic dacryocystitis is the most common diagnosis in lacrimal sac specimens obtained at DCR. Neoplasms resulting in chronic nasolacrimal duct obstruction occurred in 4.6% of cases and were unsuspected before surgery in 2.1% of patients. We recommend pathologic examination of DCR specimens.
