Juvenile xanthogranuloma of the lacrimal sac fossa.
OBJECTIVE
Masses involving the medial canthus and lacrimal sac fossa include dacryocystoceles and, less commonly, mucoceles, hemangiomas, diverticula, and lacrimal sac neoplasms. To our knowledge, juvenile xanthogranuloma presenting as a lacrimal sac fossa mass has not been previously reported.


METHODS
We examined a 2-year-old boy who had epiphora in the left eye since birth and a mass in the left lacrimal sac fossa for 6 weeks. During surgery, left lacrimal probing disclosed obstruction at the level of the common canaliculus and lacrimal sac. Exploration and excision of the mass were performed.


RESULTS
Histopathologic evaluation disclosed a juvenile xanthogranuloma characterized by an inflammatory cell infiltrate with foamy histiocytes and scattered Touton-type multinucleated giant cells.


CONCLUSIONS
Juvenile xanthogranuloma should be included in the differential diagnosis of a medial canthal and lacrimal sac fossa mass.
