Furthermore , to correlate the clinical diagnosis with the pathology diagnosis. Methods: Ret rospective review of all pathology reports from 1910 to 1999 in the files of the Eye Pathology Institute, University of Copenhagen, describing a lesion of the l acrimal drainage system. In addition, a retrospective review of all reports desc ribing a lesion of the lacrimal drainage system from the Danish Pathology Databa se. All specimens were re-evaluated, except in cases with a primary diagnosis o f dacryocystitis. In these cases a sample of 25%was re-evaluated. Results: A t otal of 643 lesions were collected. Dacryocystitis was the most frequent lesion, constituting 508 cases (79%). The remaining cases were diagnosed as dacryolith iasis (62 cases; 7.9%), tumour (29 cases; 4.5%), trauma (19 cases; 3.0%), con genital malformation (nine cases; 1.4%), canaliculitis (eight cases; 1.2%) and granulomatous inflammation (eight cases; 1.2%). Seventeen tumours were maligna nt, of which B-cell lymphoma was the most common (six cases). In 0.6%of cases with a clinical diagnosis of dacryocystitis/lithiasis a non-suspected malignant tumour was diagnosed. Micro-organisms were uncommon in dacryocystitis (9%) bu t frequent in cases of dacryolithiasis (87%). Conclusion: Dacryocystitis was by far the most frequent lesion of the lacrimal drainage system referred for histo pathological evaluation. Dacryolithiasis was often associated with micro-organi sms, especially Gram positive rods. Histopathology is necessary to confirm suspe cted tumours, more than half of which were inflammatory lesions, and to detect t umours that sometimes masquerade as inflammation.展开更多
