Quiste congénito del conducto nasolacrimal/dacriocistocele: causa de dacriocistitis no diagnosticada

Two cases of patients younger than 5 months are presented, who during the first weeks of life have recurrent muco-purulent ocular discharge. Subsequently, in endoscopy, in both cases, intranasal cystic masses were found, resulting in a diagnosis of dacryocystocele plus congenital cyst of the lacrimal duct. Dacryocystocele is an uncommon cause of nasal duct obstruction, but it becomes less common when accompanied by a congenital tear duct cyst. Due to its uncommonness and its often-atypical symptoms, it results in a complicated diagnosis for the ENT and the ophthalmologist.
