Rare Pleurostomophora richardsiae Mass Causing Transient Nasolacrimal Duct Obstruction.

Transient nasolacrimal duct obstruction secondary to a mass lesion compressing the sac or sac-duct junction is rare. We report a case of a young female who presented to us with complaints of watering and a mass lesion in the lacrimal sac region. An organized perilacrimal mass filled with thick pultaceous material was noted during surgery. Following the drainage of the mass lesion, irrigation of the lacrimal system was freely patent. Microbiological examination and DNA sequencing targeting interspacer region was suggestive of Pleurostomophora richardsiae species. To the best of authors' knowledge, this is only the second case report of a subcutaneous perilacrimal mass causing transient nasolacrimal duct obstruction by Pleurostomophora richardsiae.
