Sclerosing Perineurioma of the Orbit
Abstract
A 7-week-old boy presented to pediatric ophthalmology with a mass inferior to the medial canthus of the OS that was first noticed on day 3 of life. Crigler massages, warm compresses, and moxifloxacin HCl drops were administered without resolution of symptoms. Probing and irrigation for a presumed dacryocystocele were performed, but the nasolacrimal system was patent, and the mass persisted after the procedure. Oculoplastics was consulted for further evaluation and management. On exam, the tear lake was normal, there was no discharge to palpation of either lacrimal sac, and there was no erythema. An MRI was obtained that showed a mass with nonspecific features abutting the lacrimal sac. A gross total resection of the mass was performed, and it was sent for histopathologic evaluation. Pathology results yielded a diagnosis of sclerosing perineurioma, a rare soft tissue tumor previously unreported in the orbit.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
