Melanom, pigment \u00fcreten melanositlerden kaynaklanan bir kanser t\u00fcr\u00fc, k\u00f6peklerde \u00f6nemli bir sa\u011fl\u0131k sorunu olup, kedilerde daha az \u00f6l\u00e7\u00fcde g\u00f6r\u00fclmektedir. Bu kapsaml\u0131 k\u0131lavuz, bu hayvanlardaki melanomun \u00f6zellikleri, tan\u0131s\u0131 ve potansiyel tedavi se\u00e7enekleri hakk\u0131nda bilgi vererek, evcil hayvan sahipleri ve veteriner profesyonelleri i\u00e7in de\u011ferli bilgiler sunmay\u0131 ama\u00e7lamaktad\u0131r.<\/p>\n\n\n\n
Melanom, ciltte ve v\u00fccudun di\u011fer b\u00f6lgelerinde pigment \u00fcretiminden sorumlu h\u00fccreler olan melanositlerde ortaya \u00e7\u0131kan bir kanserdir. K\u00f6peklerde, \u00f6zellikle belirgin cilt pigmentasyonu olan \u0131rklarda, nispeten yayg\u0131n bir kanserdir. Kedilerde ise melanom daha nadirdir ancak meydana geldi\u011finde daha malign olma e\u011filimindedir.<\/p>\n\n\n\n
K\u00f6peklerde, melanomlar en s\u0131k t\u00fcyl\u00fc ciltte, k\u00fc\u00e7\u00fck, kahverengi ile siyah k\u00fctleler olarak bulunur. Ayr\u0131ca daha b\u00fcy\u00fck, d\u00fcz ve k\u0131r\u0131\u015f\u0131k k\u00fctleler olarak da g\u00f6r\u00fcnebilirler. K\u00f6peklerdeki primer melanomlar a\u011f\u0131z bo\u015flu\u011funda, t\u0131rnak yata\u011f\u0131nda, ayak taban\u0131nda, g\u00f6zde, gastrointestinal sistemde, burun bo\u015flu\u011funda, anal kesede veya mukok\u00fctan\u00f6z birle\u015fim yerlerinde de geli\u015febilir. K\u00f6peklerde a\u011f\u0131z melanomu i\u00e7in en yayg\u0131n yerler di\u015f eti, dudaklar, dil ve sert damakt\u0131r.<\/p>\n\n\n\n
\u0130nsan melanomlar\u0131 genellikle UV \u0131\u015f\u0131\u011f\u0131na maruz kalma ile ili\u015fkilendirilirken, k\u00f6pek melanomu \u00e7o\u011fu \u0131rk\u0131n koruyucu t\u00fcy \u00f6rt\u00fcs\u00fc nedeniyle g\u00fcne\u015f \u0131\u015f\u0131\u011f\u0131na atfedilme olas\u0131l\u0131\u011f\u0131 daha d\u00fc\u015f\u00fckt\u00fcr. Ancak, k\u00f6pek melanomu i\u00e7in kesin risk fakt\u00f6rleri iyi bir \u015fekilde belirlenmemi\u015ftir. Kedilerde melanom daha az yayg\u0131nd\u0131r ve nedenleri benzer \u015fekilde karma\u015f\u0131k ve tam olarak anla\u015f\u0131lmam\u0131\u015ft\u0131r.<\/p>\n\n\n\n

K\u00f6peklerdeki a\u011f\u0131z malign melanomlar\u0131nda (MM'ler), insan cilt melanomunda yayg\u0131n olan BRAF mutasyonlar\u0131 nadirdir. Ancak, insan ve k\u00f6pek MM'lerindeki ERK aktivasyon benzerlikleri, molek\u00fcler yollar a\u00e7\u0131s\u0131ndan potansiyel paralellikler \u00f6nermektedir.
