Purpose:
To report a case of canaliculops, a rare, non-inflammatory cystic dilatation of the lacrimal canaliculus, presenting with an unusual intermittent clinical course.
Observations:
A 68-year-old woman presented with recurrent medial canthal swelling and episodic epiphora caused by a cystic lesion of the superior canaliculus. The lesion was successfully managed with marsupialization and bicanalicular intubation under endoscopic guidance. Histopathological examination revealed multilayered, non-keratinized stratified squamous epithelium without goblet cells, inflammatory infiltrates, or evidence of malignancy. Immunohistochemical analysis demonstrated positivity for CK14, supporting the diagnosis of canaliculops.
Conclusion And Importance:
Most cases of canaliculops are idiopathic and exhibit a stable or slowly progressive course; however, some may present with intermittent symptoms. Increased awareness of this underrecognized entity may facilitate earlier diagnosis and appropriate management.

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
