Ectopic dacryops mimicking a lacrimal sac tumor: A case report and literature review.

PURPOSE

To report a rare case of dacryops found within the lacrimal sac, which mimicked a lacrimal sac tumor.

OBSERVATIONS

An adult female patient presented with epiphora and chronic swelling of the lacrimal sac, initially raising concerns for a possible lacrimal sac tumor. Imaging revealed a well-defined cystic lesion with a patent lacrimal drainage system. Histopathological examination confirmed the presence of a lacrimal gland cyst (dacryops) within the lacrimal sac.

CONCLUSIONS AND IMPORTANCE

This case highlights the rare occurrence of lacrimal gland tissue within the lacrimal sac, a location that has eluded prior definitive descriptions in the literature. Recognition of this condition is crucial for appropriate diagnosis and management, as it can mimic more serious pathologies such as a lacrimal sac tumor.
