Imunofenotipsko obilježje mješovitog tipa gingivo-vaskularnog hamartoma u teleta - prikaz slučaja.

A one month-old heifer calf affected by gingival vascular hamartoma, of measured mass 3×2.5×2 cm is presented. This gingival vascular hamartoma was a mixture of redundant vessels ranging from capillaries or capillary buds and large arteries separated by edematous and loose fibrostroma. The results of Immunohistochemistry showed strong expression of the alpha smooth muscle Actin, weak reaction of the Von Willebrand factor and negative reaction of Vimentin, CD31, Ki67 and PCNA in endothelial cells, suggesting vascular hamartoma.Prikazan je slučaj gingivo-vaskularnog hamartoma velikog 3×2,5×2 cm u jednomjesečnoga ženskog teleta. Hamartom se sastojao od mješavine krvožilja, od kapilara do nezreloga kapilarnog tkiva i velikih arterija odvojenih edematoznom i rahlom fibrostromom. Rezultati imunohistokemije pokazali su jaku izraženost aktina alfa-glatkih mišića, slabu reakciju Von Willebrandovog faktora i negativnu reakciju na vimentin, CD31, Ki67 i PCNA u endotelnim stanicama, što upućuje na hamartom
