Cutaneous hornhttps://en.wikipedia.org/wiki/Cutaneous_horn
Cutaneous horn zidumba ze‑keratinous ezingaqhelekanga ezinembonakalo yeempondo, okanye ngamanye amaxesha ngamaplanga okanye ikorale. Ngokuqhelekileyo zincinci kwaye zenziwe zasekhaya kodwa zinokuthi, kwiimeko ezinqabileyo kakhulu, zibe zikhulu kakhulu. Zisenokuba neebhubhiso (malignant) okanye ezingaphambili kokuba zibe neebhubhiso (premalignant).

Ubhubhiso (malignancy) bukho kwi‑20% yeemeko, kunye ne‑squamous‑cell carcinoma (squamous cell carcinoma) eyona nto iqhelekileyo. Ukunyuka koonobangela we‑squamous‑cell carcinoma kufikelela kwi‑37% xa isilonda senzeka kwilungu lobudoda (penis).

i-horn yesikhumba (Cutaneous horn) ngokusisiseko kukukhula okubonakalayo okufana nophondo lwesilwanyana esimhlophe okanye esityheli xa usijongile. Ngoku kuyaqondwa ngokubanzi ukuba ezi mpondo zivela njengempendulo kwimiba yolusu eyahlukeneyo—ezinye zibuthathaka, ezinye zinokujika zibe ngumdlavuza. I-Actinic keratoses (Actinic keratoses) zi zizathu ezivamile ezibangelwa umdlavuza ongakafiki (premalignant), ngelixa i-squamous cell carcinoma (SCC) yimbangela ephambili yomdlavuza.
A cutaneous horn is usually evident upon physical examination and can be described as a white or yellow exophytic protrusion in the shape of an animal horn. Cutaneous horns are now widely accepted as a reactive cutaneous growth caused by a variety of benign, premalignant, or malignant primary processes. Actinic keratoses are the most common premalignant primary cause of cutaneous horn, while squamous cell carcinoma (SCC) is the most common malignant cause.

Cutaneous horn sisihluma esishinyeneyo esimile okwekhorn kunye nesikhumba esijiyileyo, esihlala sifana nophondo lwesilwanyana. Ligama elichaza ukwakheka okungaqhelekanga kweeseli zolusu ezinzima, endaweni yesifo esithile. Cutaneous horns inokuphuhla ecaleni kweemeko zolusu ezinobungozi, ngaphambili, okanye ezinomhlaza. Eyona nto iphambili ixhalabisayo kukwahlula phakathi kwebala lolusu elonakeleyo elijiyileyo kunye nokukhula okunokuba ngumhlaza okufana ne‑squamous cell carcinoma (squamous cell carcinoma). Omnye unobangela yikeratoacanthoma, ebonakala njengethumba eliphakanyisiweyo, elifana nezikhonkwane. Unyango lubandakanya ukususa uphondo kwaye uluvavanye phantsi kwe‑microscope ukujonga umhlaza.
Cutaneous horn is a dense, cone-shaped growth with thickened skin, often resembling an animal's horn. It's a term describing an unusual buildup of hardened skin cells, rather than a specific disease. Cutaneous horns can develop alongside various benign, pre-cancerous, or cancerous skin conditions. A key concern is distinguishing between a thickened sun-damaged skin spot and a potentially cancerous growth like squamous cell carcinoma. Another culprit is keratoacanthoma, which presents as a raised, nail-like tumor. Treatment typically involves removing the horn and examining it under a microscope to check for cancer.
