Rare Pleurostomophora richardsiae Mass Causing Transient Nasolacrimal Duct Obstruction

Abstract

Transient nasolacrimal duct obstruction secondary to a mass lesion compressing the sac or sac-duct junction is rare. The authors report a case of a young female who presented to the authors 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 the authors' knowledge, this is only the second case report of a subcutaneous perilacrimal mass causing transient nasolacrimal duct obstruction by Pleurostomophora richardsiae.

The reliability of patient-reported mucoid reflux on nasolacrimal sac compression

“…However, even with a positive or negative patient-reported self-ROPLAS the clinician should still palpate and examine the medial canthus and nose, as many exogenous lacrimal sac masses may or may not cause secondary NLDO with or without reflux. 4,5…”

Subcutaneous phaeohyphomycosis caused by Pleurostomophora richardsiae in a renal transplant recipient

“…With only 25 cases of human infections reported to date since its identification in 1968,1, 2, 3 P richardsiae is a rare dematiaceous (dark-colored) fungus found in woody plants that most commonly presents as subcutaneous phaeohyphomycosis, as seen in our patient. It is believed to be more common in the tropics and subtropics 4 .…”

Absceso frío en una mano por un hongo dematiáceo. Primera comunicación en Chile de Pleurostomophora richardsiae

“…Predominan reportes del hemisferio norte en pacientes inmunocompetentes o inmunocomprometidos, incluyendo en el último caso a pacientes sometidos a trasplante de órganos sólidos o terapia corticoesteroidal. El espectro clínico incluye infecciones de tejidos blandos, endocarditis o fungemia, endoftalmitis o infección del saco lacrimal (Tabla 1) 12,13,[16][17][18][20][21][22][23][24] . El tratamiento ha contemplado compuestos antifúngicos en monoterapia o combinaciones y aseo quirúrgico.…”
