A rare dacryolith (lacrimal stone) caused a conjunctival mass in a patient's temporal canthus. Surgical removal and duct irrigation were effective treatments for this unusual lacrimal duct obstruction.
Area of Science:
- Ophthalmology
- Pathology
Background:
- Conjunctival masses can present with varied etiologies.
- Temporal canthus masses are uncommon presentations for lacrimal system pathologies.
Purpose of the Study:
- To report a rare case of dacryolithiasis presenting as a conjunctival mass.
- To highlight the importance of considering dacryoliths in the differential diagnosis of temporal canthus masses.
Main Methods:
- Case presentation of a 31-year-old female with a persistent conjunctival mass.
- Incision and curettage for mass removal.
- Histopathological examination to identify the concretion.
- Lacrimal duct irrigation post-resection.
Main Results:
- An 8 mm concretion was removed from the left temporal canthus.
- Histopathology confirmed the concretion as a dacryolith within the lacrimal duct.
- The patient's symptoms resolved following surgical intervention and irrigation.
Conclusions:
- Dacryoliths, though rare, should be considered in the differential diagnosis of temporal canthus masses.
- Surgical resection of the dacryolith combined with lacrimal duct irrigation is an effective treatment.
- Prompt diagnosis and management are crucial for resolving symptoms associated with lacrimal duct obstructions.
