Abstract

Purpose
We assessed the clinical utility of routine histopathological evaluation of the lacrimal sac during dacryocystorhinostomy.
Methods
From April 2009 to April 2018, we included 1,619 eyes of 1,266 patients who underwent dacryocystorhinostomy in our hospital. All lacrimal sacs were histopathologically examined. We excluded cases in which malignant lacrimal sac tumors had been preoperatively diagnosed. We retrospectively analyzed the medical records in terms of clinical manifestations, histological findings after lacrimal sac biopsy, and malignant tumors. We recorded the age, extent of bone marrow involvement, stage, and prognosis of patients with malignancies.
Results
We treated 217 males and 1,049 females of a mean age at diagnosis of 58.8 ± 12.3 years. The biopsy data showed that chronic inflammation with fibrosis (n = 1,026 [81.0%]) was the most common condition, followed by fibrosis (n = 133 [10.5%]), chronic inflammation (n = 94 [7.4%]), reactive lymphoid hyperplasia (n = 5 [0.4%]), malignant tumors (n = 4 [0.3%]), tubular adenomas (n = 2 [0.2%]), and papillomas (n = 2 [0.2%]). All malignant tumors were mucosal-associated lymphoid tissue lymphomas. Two of these four patients underwent additional imaging tests, but malignancies were not apparent. The other two had no specific complaints other than tearing. In addition, no abnormalities were evident on slit lamp examination or the syringing test. All four patients were cured by chemotherapy.
Conclusions
No clinical manifestation, physical examination or imaging data, or intraoperative finding in patients with nasolacrimal duct obstructions reliably identify a malignancy; but histological examination does.
