Cutaneous horn is yn prinsipe in sichtbere groei dy't liket op in wite of giele bistehoarn, lykas jo dernei sjogge. It is no wiid begrepen dat dizze hoarnen opkomme as in reaksje op ferskate hûdproblemen – guon goedaardige, guon dy't mooglik kankeraas binne. Actinic keratoses binne de meast foarkommende net‑kankerlike oarsaak, wylst squamous cell carcinoma (SCC) de meast foarkommende kankeroarsaak is.
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: a potentially malignant entity 20043059Cutaneous horn is in tichte, kegelformige groei mei ferdikte hûd, dy't faak liket op in bist syn hoarn. It is in term dy't in ûngewoane opbou fan ferhurde hûdsellen beskriuwt, ynstee fan in spesifike sykte. Cutaneous horns kinne ûntstean by ferskate goedaardige, pre‑kankerlike of kankerige hûdomstannichheden. In wichtige soarch is it ûnderskiede tusken in dikke, sinnebeseaide hûdplak en in mooglik kankerige groei lykas plaveiselcelcarcinoma. In oare mooglike oarsaak is keratoacanthoma, dat presintearre wurdt as in ferhege, spikerlike tumor. De behanneling omfettet typysk it fuortheljen fan 'e hoarn en it ûndersyk ûnder in mikroskoop om op kanker te kontrolearjen.
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.
Maligniteit is oanwêzich yn maksimaal 20% fan de gefallen, mei squamous‑cell carcinoma it meast foarkommende type. De ynsidinsje fan squamous‑cell carcinoma is oant 37% as de lesion oanwêzich is op de penis.
