Wyprysk z hiperkeratozą - Objawy, Diagnoza i Leczenie
Lokalizacje odcisku:
- palce stóp (okolica grzbietowa stawy międzypaliczkowe, boczna i przyśrodkowa powierzchnia palców w miejscu stykania się skóry Clavus mollis, okolica podeszwowa palca – Clavus appex)
- przodostopie (głowy kości śródstopia)
- wały paznokciowe (clavus sulcus)
- przestrzenie podpaznokciowe (clavus subungualis)
Clavus durus (Cd) – zbudowany jest ze zwartej i twardej masy ułożonej warstwowo (nawet do 200 warstw), zawierający jądro.
Clavus mollis (Cm) – to inaczej odcisk miekki.
Clavus vascularis (Cv) – to odcisk z zawartością drobnych naczyń krwionośnych.
Clavus neurovascularis (Cnv) – odcisk nerwowo – naczyniowy.
Clavus neurofibrosis (Cnf) – odcisk nerwowo – włóknisty.
Clavus papilaris (Cp) – to odcisk brodawkowy. Często się powtarza.

Hyperkeratosis refers to the increased thickness of the stratum corneum, the outer layer of the skin. It is most frequently due to chronic physical or chemical damage such as friction or the use of aggressive soaps but can also derive from chronic inflammation or a side-effect of different drugs, including chemotherapy. This activity reviews the evaluation and treatment of hyperkeratosis and highlights the role of the interprofessional team in evaluating and treating patients with this condition.
Summarize the major histologic forms of hyperkeratosis. Review the different pathologies that can manifest with hyperkeratosis.Explain the importance of collaboration and communication amongst the interprofessional team to ensure the appropriate diagnosis and treatment is selected for patients with hyperkeratosis.
Toxicokinetics
BCR-ABL inhibitors (mainly nilotinib and dasatinib) are commonly used for ontological target therapy, and the cutaneous side effects are only second to the hematologic sequelae. They are usually transitory and not severe. The most common dermatological side effect is a pruritic skin rash, while chronic dermatological side effects include psoriasis, lichenoid hyperkeratosis, pityriasis, and others.[14][15][16]
Multikinase-inhibitors (VEGF, PDGFR, EGFR, KIT, RET, Flt3, and RAF) affect the skin homeostasis and give rise to many different cutaneous manifestations, mainly with hyperkeratosis in the form of hyperkeratotic hand-foot skin reaction.[14] Hyperkeratosis occurs in the sites of friction or pressure, mainly soles, causing pain and limitation of the daily activities.[17][18]
