摘要:
BACKGROUND Nasolacrimal duct obstruction leading to epiphora is a common ophthalmologic complaint,and it may derive from amyloidosis in rare cases.There are a few reports about localized amyloidosis,and amyloidosis with involvement and obstruction of the nasolacrimal duct is exceedingly rare.CASE SUMMARY A 54-year-old male presented with a 2-year history of a lump overlying the left lacrimal sac that had grown rapidly for nearly half a year.Physical examination touched a firm lump in the left lacrimal sac.Nasal endoscopy discovered lesions in appearance of sediments with easy bleeding at the entry of the nasolacrimal duct of the left inferior nasal meatus.Computerized tomography scan revealed speckle high density in the left lacrimal sac and the dilated nasolacrimal duct.During an endoscopic exploration and excision,a large number of dacryoliths were exposed.Pathology indicated amorphous pink material and multinucleated giant cell reaction in the fibrous tissue.CONCLUSION This case showed amyloidosis in localized form mimicking dacryolith with nasolacrimal duct obstruction.In clinical practice,we should be aware of the possibility of localized amyloidosis in the nasolacrimal excretory system.
