title: Histopathology of nasolacrimal duct obstruction compatible with localized sarcoidosis.
abstract: We report a case of nasolacrimal duct obstruction with histopathology compatible with localized sarcoidosis, in a patient with no evidence of systemic disease. Excisional biopsy of the nasolacrimal duct revealed multiple noncaseating granulomas. Previously reported cases of sarcoidosis involving the lacrimal drainage system all had systemic disease, and these case are reviewed. Our case illustrates the potential value of nasolacrimal duct biopsy during dacryocystorhinostomy.
