67290009: Hair follicle structure (body structure)

SNOMED CT Concept\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 (body structure)\Structure of skin region\Hair-bearing skin\Hair follicle structure

Virus-associated trichodysplasia spinulosa is a rare infectious skin disease characterized by the development of follicular papules with keratin spicules in various parts of the body, predominantly in the face (e.g. nose, eyebrows, auricles), that is due to polyomavirus infection in immunocompromized patients.

A parasitic disease characterized by infestation of the skin with larvae of a variety of fly species. Furuncular myiasis specifically involves flies whose eggs are able to breach healthy skin, which concerns three species: Cordylobia anthropophaga (also called the African tumbu fly or Cayor worm for the larvae) and Cordylobia rodhaini (the Lund's fly), and Dermatobia hominis (the human botfly).

A rare inherited cancer-predisposing syndrome characterized by skin lesions, kidney tumors, and pulmonary cysts that may be associated with pneumothorax. The kidney tumors range from benign oncocytomas to malignant renal cell carcinomas including chromophobe, clear cell or papillary subtypes. Fibrofolliculomas are characterized by a circumscribed proliferation of collagen and fibroblasts surrounding distorted hair follicles from which basaloid cells protrude into the surrounding fibromucinous stroma. Other characteristic skin anomalies are trichodiscomas and acrochordons. Dermatological manifestations usually develop in the third and fourth decades of life and persist indefinitely. The syndrome is transmitted in an autosomal dominant fashion.	Finding site	True	Hair follicle structure	Inferred relationship	Some	1
