Khansa ya Impso

Kansa ya maselo a impso ndi chotupa choipa chochokera ku dongosolo la mkodzo la epithelial la impso parenchyma. Dzina la maphunziro ndi renal cell carcinoma, lomwe limadziwikanso kuti renal adenocarcinoma, lomwe limatchedwa renal cell carcinoma.

Lili ndi mitundu yosiyanasiyana ya khansa ya impso yochokera m'magawo osiyanasiyana a mkodzo, koma silikuphatikizapo zotupa zochokera ku renal interstitium ndi renal pelvis.

Kale mu 1883, Grawitz, katswiri wa matenda a ku Germany, anaona kuti mawonekedwe a maselo a khansa anali ofanana ndi a maselo a adrenal pogwiritsa ntchito maikulosikopu, ndipo anaika patsogolo chiphunzitso chakuti khansa ya maselo a impso ndiyo chiyambi cha minofu ya adrenal yomwe imatsala mu impso. Chifukwa chake, khansa ya maselo a impso inkatchedwa Grawitz tumor kapena chotupa chofanana ndi adrenal m'mabuku asanayambe kusintha ndi kutsegulidwa ku China.

Mpaka mu 1960, Oberling adapereka lingaliro lakuti khansa ya maselo a impso inachokera ku proximal convoluted tubule ya impso kutengera kuwona kwa ma electron microscopic, ndipo cholakwika ichi sichinakonzedwe.
