Intestinal adenocarcinoma in a European brown bear (Ursus arctos) - a case report

This article presents the first case of intestinal adenocarcinoma in a free living, culled 12 year old, European female brown bear (Ursus arctos), with its characteristic macropathological and histopathological manifestations. Necropsy revealed thoracic gunshot injuries (compassionate shot) and the...

description This article presents the first case of intestinal adenocarcinoma in a free living, culled 12 year old, European female brown bear (Ursus arctos), with its characteristic macropathological and histopathological manifestations. Necropsy revealed thoracic gunshot injuries (compassionate shot) and the poor physical condition of the animal, with body fat loss and musculature atrophy. An infiltrative mass protruded the jejunal wall with infiltration of the mesentery, visceral and parietal peritoneum, and distal parts of the colon and rectum. The histopathological examination presented an infiltrative, unencapsulated, moderately cellular neoplastic mass, composed of an epithelial cell population, forming irregular nests, papillary and ribbon like structures and small number of tubules, surrounded by an extensive desmoplastic reaction. Within the tumor a small number of cysts filled with mucin were noted. The epithelial neoplastic cells exhibited mild anisocytosis and anisokaryosis, and a low mitotic index. Histochemical Van Gieson staining showed strong positivity in the desmoplastic proliferation. The epithelial tumor cells were positively imunostained with cytokerain, and stromal cells with vimentin. The histological features presented are characteristic of intestinal adenocarcinomas, of the mixed tubular and mucinous type, with a prominent scirrous reaction. Ovaj članak prikazuje prvi dijagnosticirani slučaj adenokarcinoma crijeva kod 12 godina stare ženke odstrijeljenog slobodnoživućeg smeđeg medvjeda (Ursus arctos), s karakterističnim makroskopskim i histopatološkim svojstvima. Obdukcijom je utrvđena ustrijelna rana (samilosni hitac) na prsnome košu, jaka mršavost s nedostatkom masnoga tkiva i atrofijom mišića. Na jejunumu je ustanovljena infiltrativna masa koja je infiltrirala stijenku crijeva te zahvatila mezenterij, visceralni peritoneum te distalne dijelove rektuma i kolona. Histopatološkom je pretragom utvrđena infiltrativna, neinkapsulirana, umjereno stanična neoplastična masa koja je građena od epitelnih stanica koje formiraju nepravilna gnijezda, papilarne i trakaste strukture te manji broj tubula okruženih jakom dezmoplastičnom reakcijom. Unutar tumora nalazio se manji broj cista ispunjenih sa sluzi. Epitelne neoplastične stanice pokazivale su slabiji stupanj anizocitoze i anizokarioze te nizak mitotski indeks. Histokemijsko Van Giesonovo bojenje pokazalo je jaku pozitivnu reakciju u području dezmoplastične proliferacije. Imunohistokemijska je pretraga pokazala pozitivnu reakciju epitelnih tumorskih stanica na citokeratin, a vezivnotkivnih stanica na vimentin. Utvrđena su histopatološka svojstva karakteristična za adenokarcinom crijeva, mješoviti tubularni i cistični oblik s jakom skiroznom reakcijom.
