Wyprysk z hiperkeratozą - Objawy, Diagnoza i Leczenie
METODY USUWANIA HYPERKERATOZ
Farmakologiczne
- retinoidy (leczenie rogowca)
- suplementacja witaminowo-minerałowa
- leki o działaniu uzależnionym od współistniejącego schorzenia
- preparaty zawierające kwas salicylowy (2-50%)
- preparaty zawierające mocznik (20-50%)
Podologiczne
są to specjalistyczne działania, mające na celu mechaniczne usuwanie zrogowaceń. Dobór metody uzależniony jest od rodzaju i rozległości hyperkeratoz. Zazwyczaj jest to długofalowa terapia obejmująca systematyczne zabiegi w gabinecie pielęgnacji stóp oraz edukację klienta, a także właściwe postępowanie domowe.
Paramedyczne i/lub domowe
są to metody wykorzystywane samodzielnie przez klientów. Zaliczyć tu można zarówno preparaty i środki dostępne bez recepty w aptekach oraz drogeriach, jak i sposoby zasłyszane lub znalezione, np. w internecie. Chęć uzyskania szybkiego efektu, a także niewłaściwe wykorzystanie metody prowadzi do licznych powikłań.
Histopathology
Psoriasis and psoriasiform dermatitis: It shows perivascular aggregates of lymphocytes in the dermal-epidermal junction with focal migration of leukocytes (neutrophils, lymphocytes) into the epidermis. There is increased epidermal proliferation and elongation of rete ridges giving an undulating appearance to the epidermis (papillomatosis) with or without spongiosis. The altered differentiation of keratinocytes results in hyperkeratosis with parakeratosis. Psoriasis also shows the formation of microabscesses by small aggregates of neutrophils in the upper epidermis (pustules) or in the stratum corneum (Munro microabscesses).
Interface and lichenoid dermatitis: Dense aggregates of lymphocytes along the dermal-epidermal junction associated with vacuolation of basal keratinocytes.[6] There is dyskeratosis, hyperkeratosis, and is sometimes associated with hypergranulosis.
Verrucae vulgaris and plana are characterized by marked hyperkeratosis, papillomatosis, and acanthosis. A typical feature is the presence of koilocytes, cells infected with papillomavirus which have structural changes like perinuclear halos and keratohyalin granules. Koilocytes can be absent in older lesions, but when present, are located in the upper stratum spinosum or granulosum. Parakeratosis may be present.
Seborrheic keratosis features marked hyperkeratosis, papillomatosis, and acanthosis. Pseudo-cysts and horn cysts are frequently present. There may be lymphocytic infiltrate and pigmentation as secondary features when irritated or inflamed.
The ichthyoses are a group of diseases caused by altered keratinization. The most common forms are ichthyosis vulgaris, X-linked, congenital, and epidermolytic hyperkeratosis.[7] They can be hereditary or acquired during life.[8][9] All of the forms show a defective epidermal barrier that induces hyperkeratosis, skin scaling, and inflammation.
Squamous cell carcinoma (SCC) is a neoplastic proliferation of atypical keratinocytes, restricted only to the epidermis (SCC in situ or Bowen's disease) or infiltrating the dermis (infiltrative SCC). Classic features are hyper-parakeratosis and loss of the granular layer.
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]
