Wyprysk z hiperkeratozą - Objawy, Diagnoza i Leczenie
Introduction
Hyperkeratosis refers to the increased thickness of the stratum corneum, the outer layer of the skin. Stratum corneum is composed of multiple layers of keratinocyte bodies that, during maturation, produced keratin and subsequently have lost their nucleus and cytoplasmic organelles. The result is a basketweave appearance of anucleate keratinocytes that protect the underlying cells during maturation.
Hyperkeratosis is subclassified as orthokeratotic or parakeratotic. Orthokeratotic hyperkeratosis refers to the thickening of the keratin layer with preserved keratinocyte maturation, while parakeratotic hyperkeratosis shows retained nuclei as a sign of delayed maturation of keratinocytes. Hyperkeratosis can be associated with dyskeratosis. It represents a premature (keratinocytes that are located below the granular cell layer) or abnormal keratinization of individual keratinocytes.
Hyperkeratosis, associated with other abnormalities in the skin biopsy, can be a key to the final histological diagnosis. Epidermal hypertrophy is a benign alteration of the skin that presents with acanthosis (increased thickness of the keratinocyte layers) and hyperkeratosis.
Types of Hyperkeratosis
"Hyperkeratosis" is an umbrella term for skin conditions that develop from excess amounts of keratin. There are various types of hyperkeratosis, each marked by its cause.
Hereditary Types of Hyperkeratosis
Some types of hyperkeratosis develop due to a hereditary component. Examples include:
- Epidermolytic hyperkeratosis
- Multiple minute digitate hyperkeratosis (MMDH)
- Focal acral hyperkeratosis
- Lamellar ichthyosis
- X-linked ichthyosis (XLI)
- Keratosis pilaris, otherwise known as follicular hyperkeratosis
Acquired Hyperkeratosis
Other forms of hyperkeratosis are acquired later in life. It’s not always clear what the cause of each type is. Some acquired hyperkeratosis conditions include:
Acquired vs. Hereditary
Hereditary conditions are passed down through families. Often if a person is related by blood to someone with a genetic disorder, their risk of getting it is a lot higher. Acquired conditions, on the other hand, develop for many reasons unrelated to genetics.
Jakie są przyczyny hiperkeratozy?
Przyczyny hiperkeratozy mogą mieć różnorodne podłoże. Należą do nich:
- tarcie i ucisk,
- problemy hormonalne,
- reumatyzm,
- cukrzyca,
- nadwaga,
- reakcje uczuleniowe,
- niedobory witamin,
- kontakt z silnymi środkami chemicznymi (np. detergentami),
- zbyt sucha skóra,
- dziedziczne choroby genetyczne, np. rybia łuska,
- łuszczyca,
- atopowe zapalenie skóry,
- podrażnienia mechaniczne,
- infekcje grzybicze i bakteryjne.
W przypadku hiperkeratozy na stopach do przyczyn zalicza się również:
- źle dobrane obuwie,
- zdeformowaną budowę stopy,
- konieczność stania przez długi czas,
- długie spacery i marsze,
- biegi długodystansowe,
- zbyt dużą potliwość stóp,
- brak odpowiedniej higieny stóp.
