15753006: Nasolacrimal duct structure (body structure)

SNOMED CT Concept\Body structure (body structure)\Anatomical or acquired body structure (body structure)\Anatomical structure\...

\An anatomical structure that consists of the maximal set of organ parts so connected to one another that together they constitute a self-contained unit of macroscopic anatomy, distinct both morphologically and functionally from other such units. Together with other organs, an organ constitutes an organ system or a body part. An organ is divisible into organ parts but not organs (examples: femur, biceps, liver, heart, aorta, sciatic nerve, ovary).\Duct (organ) structure\Lacrimal drainage structure\Structure of lacrimal gland duct (body structure)\Nasolacrimal duct structure

A rare, genetic, otorhinolaryngological malformation characterized by congenital impatency of the nasolacrimal drainage system in various members of a family. Presentation is not specific and may include a uni- or bilateral medial canthal mass, dacryocystitis, nasal obstruction, periorbital cellulitis, and epiphora. Dacryocystocele and lacrimal puncta agenesis may be associated.	Finding site	True	Nasolacrimal duct structure	Inferred relationship	Some	1
Nasolacrimal duct cyst describes a unilateral or bilateral congenital cyst of the nasolacrimal duct, which is almost always associated with dacryocystocele, presenting most commonly at birth or a few weeks of age (but rarely presenting in adulthood) as a benign, grayish blue mass in the inferomedial canthus or in the nasal cavity, that can cause epiphora, dacryocystitis (inflammation of the lacrimal sac) and nasal obstruction. It is more commonly reported in females.	Finding site	True	Nasolacrimal duct structure	Inferred relationship	Some	1
