title: Pityrosporum species associated with dacryoliths in obstructive dacryocystitis.
abstract: Two dacryoliths removed from the obstructed and enlarged lacrimal sac of a 54-year-old woman during dacryocystorhinostomy were found to contain filamentous forms consistent with Pityrosporum orbiculare. To my knowledge, this fungus has not been observed before in a dacryolith or in dacryocystitis.
