770828005: Structure of nail matrix (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).\Organ part\Skin part\Structure of skin region\Skin structure of limb\Skin of part of limb (body structure)\Skin of digit\Skin of part of digit\Nail unit is a complex structure which consists of nail plate, nail bed, nail root and skin around the nail plate.\Nail unit part\Structure of nail matrix (body structure)

A rare, benign, nail tumor originating in the nail matrix characterized by localized pachyonychia and variable degrees of pigmentation: pigmented, melanocytic (common, longitudinal melanonychia that may simulate a foreign body) or hypopigmented. Histopathology demonstrates a purely epithelial tumor with endokeratinization in the deep portion and concentrically arranged nests of prekeratogenous and keratogenous cells.

Onychomatricoma is a rare, benign nail tumor originating in the nail matrix characterized by localized or diffuse thickening of the nail plate, increased transverse or longitudinal overcurvature, a yellow longitudinal band of variable width, swelling of the proximal nail fold, multiple splinter hemorrhages and the presence of honeycomb-like cavities in the distal margin of the nail plate. Nail dystrophy and dorsal pterygium may be associated. Occasionally, a pigmented lesion has been reported.	Finding site	True	Structure of nail matrix (body structure)	Inferred relationship	Some	1
