Qhov sib txawv tseem ceeb ntawm acanthosis thiab acantholysis yog acanthosis hais txog cov thickened epidermis thaum acantholysis yog qhov poob ntawm intercellular kev sib txuas ntawm keratinocytes.
Acanthosis thiab acantholysis yog ob qho kev mob ntawm daim tawv nqaij uas cuam tshuam rau cov epidermis. Acanthosis yog cov thickened epidermis. Qhov nce thickness ntawm malpighian txheej yog ua rau acanthosis. Acantholysis yog qhov poob ntawm kev sib txuas ntawm cov cell uas ua rau poob ntawm cohesion ntawm keratinocytes. Nws pom muaj kab mob xws li pemphigus vulgaris.
Acanthosis yog dab tsi?
Acanthosis txhais tau tias yog cov tawv nqaij tawv tawv. Qhov tseeb, nws yog qhov nce thickness ntawm malpighian txheej (stratum basale thiab stratum spinosum) ntawm lub epidermis. Acanthosis tseem hu ua epidermal hyperplasia. Nws tuaj yeem ua tsis tu ncua nrog rete ridges ntawm qhov ntev zoo sib xws lossis tsis xwm yeem nrog rete ridges nrog qhov sib txawv ntawm qhov ntev thiab dav. Acanthosis cuam tshuam nrog kev hloov pauv hauv stratum corneum xws li parakeratosis lossis orthokeratotic hyperkeratosis. Acanthosis (squamous cell hyperplasia) yuav pom qee zaus raws li kev kho mob. Ntxiv mus, nws pom muaj zinc deficiency. Hauv malignant melanoma, qhov tseem ceeb acanthosis nrog elongated epidermal rete yog ib hom kab mob histopathologic. Tsis tas li ntawd, muaj cov cim acanthosis, nrog qee qhov papillomatosis thiab hyperkeratosis.
Daim duab 01: Acanthosis
Acantholysis yog dab tsi?
Keratinocytes yog ib qho ntawm plaub hom kab mob epidermal. Lawv suav txog ntau dua 95% ntawm cov hlwb hauv cov epidermis. Keratinocytes tso cov protein hu ua keratin. Keratin ua rau daim tawv nqaij impermeable rau dej. Acantholysis yog kev sib cais ntawm keratinocytes nyob rau hauv lub epidermis. Nws tshwm sim vim qhov poob ntawm kev sib txuas ntawm cov cellular ntawm keratinocytes. Yog li ntawd, keratinocytes xoob cohesion ntawm lawv. Adherence ntawm keratinocytes yog kho los ntawm nruj junctions, adherens junctions, sib txawv junctions, thiab desmosomes. Acantholysis tshwm sim vim qhov tsis ua tiav ntawm kev ncaj ncees ntawm intercellular thiab intraepidermal cell junctions.
Daim duab 02: Acantholysis
Acantholysis ua rau kev sib cais ntawm cov hlwb epithelial. Nws kuj ua rau muaj kev hloov pauv ntawm cov duab ntawm tes los ntawm polygonal mus rau puag ncig. Acantholysis tuaj yeem pom hauv cov kab mob xws li pemphigus vulgaris thiab lwm yam kab mob.
Dab tsi zoo sib xws ntawm Acanthosis thiab Acantholysis?
- Acanthosis thiab acantholysis yog ob txheej txheem cuam tshuam rau cov epidermis.
- Qhov txawv txav epidermis yog tshwm sim los ntawm ob txheej txheem.
Qhov txawv ntawm Acanthosis thiab Acantholysis yog dab tsi?
Ob leeg acanthosis thiab acantholysis yog ob yam kab mob ntawm daim tawv nqaij. Acanthosis yog thickening ntawm lub epidermis. Lub caij no, acantholysis yog qhov poob ntawm intercellular kev sib txuas ntawm keratinocytes nyob rau hauv lub epidermis. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm acanthosis thiab acantholysis. Acanthosis yog qhov tseem ceeb hauv cov kab mob xws li malignant melanoma, papillomatosis thiab hyperkeratosis thaum acantholysis yog txuam nrog pemphigus vulgaris thiab lwm yam kab mob.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm acanthosis thiab acantholysis.
Summary – Acanthosis vs Acantholysis
Qhov sib txawv tseem ceeb ntawm acanthosis thiab acantholysis yog tias acanthosis yog cov epidermal thickening thiab elongation ntawm rete ridges. Tab sis, acantholysis yog kev sib cais ntawm keratinocytes nyob rau hauv lub epidermis. Acanthosis tuaj yeem pom qee zaus raws li kev kho mob. Acantholysis tuaj yeem pom hauv cov kab mob xws li pemphigus vulgaris thiab lwm yam kab mob. Yog li, qhov no qhia txog qhov sib txawv ntawm acanthosis thiab acantholysis.
