Granular cell tumor of the lacrimal sac and nasolacrimal duct: no invasive behavior with incomplete resection.
OBJECTIVE
Granular cell tumors are rare tumors of the periorbital region, and we present the second such case in the lacrimal sac. The natural history and clinical behavior of these tumors is reviewed.


METHODS
Case report.


METHODS
The clinical presentation, workup, surgical approach, and pathology of a case of granular cell tumor of the lacrimal sac are presented.


RESULTS
There has been no recurrence of the lacrimal sac tumor with incomplete resection.


CONCLUSIONS
This case history further adds to the understanding of the biologic behavior of granular cell tumors in the periorbital region.
