About: Trachonychia

An Entity of Type: disease, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Trachyonychia, is a condition characterized by rough accentuated linear ridges (longitudinal striations) on the nails of the fingers and toes. When the condition occurs on all the twenty nails of the fingers and toes, it is known as twenty-nail dystrophy, most evident in childhood, favoring males. Trachyonychia causes the nails to become opalescent, thin, dull, fragile, and finely longitudinally ridged, and, as a result, distally notched. It can be a manifestation of lichen planus, psoriasis, alopecia areata, immunoglobulin A deficiency, atopic dermatitis, and ichthyosis vulgaris.

dbo:abstract
  • La traquioniquia es una enfermedad de las uñas de causa desconocida que se caracteriza porque su superficie adopta un aspecto rugoso con estriaciones longitudinales y pequeñas depresiones, dándole al aspecto de haber sido dañadas con un papel de lija. Puede aparecer solamente en algunas uñas o afectar a la totalidad, tanto de las manos como de los pies, en cuyo caso se denomina distrofia de las 20 uñas.​ La traquioniquia puede aparecer como un fenómeno aislado, o bien asociarse a otras enfermedades de la piel, como alopecia areata, liquen plano y psoriasis. En general se considera un proceso inflamatorio benigno que afecta con más frecuencia a niños y adolescentes de ambos sexos. Es raro a partir de los 30 años. La causa de la enfermedad es desconocida, se ha especulado con la posibilidad de que sea de origen autoinmune. Otros autores consideran que puede deberse a una alteración genética, pues se ha observado que algunos casos tienen carácter familiar.​ (es)
  • Trachyonychia, is a condition characterized by rough accentuated linear ridges (longitudinal striations) on the nails of the fingers and toes. When the condition occurs on all the twenty nails of the fingers and toes, it is known as twenty-nail dystrophy, most evident in childhood, favoring males. Trachyonychia causes the nails to become opalescent, thin, dull, fragile, and finely longitudinally ridged, and, as a result, distally notched. It can be a manifestation of lichen planus, psoriasis, alopecia areata, immunoglobulin A deficiency, atopic dermatitis, and ichthyosis vulgaris. "The longitudinal striations can occur as a normal part of the aging process", and not until the nails start to thin and get a sandpaper look is the condition called trachonychia. The nails are opalescent and frequently are brittle and split at the free margin. There has been evidence of the condition as a cutaneous manifestation of lichen planus. It has also been associated with other diseases such as eczema, psoriasis, alopecia areata, and atopic dermatitis. Trachonychia is often seen in vitiligo patients – suggesting that they are more susceptible to this condition. (en)
  • La distrofia delle venti unghie (o delle venti dita) è una condizione in cui tutte le unghie del corpo (da qui il nome “venti unghie”) risultano colpite da trachionichia, un'alterazione patologica della lamina ungueale che appare ruvida, opaca, fragile e solcata da striature longitudinali. Tale anomalia si manifesta solitamente nell'infanzia. (it)
