Cista (Cyst) je zaprta vreča. cista (cyst) lahko vsebuje zrak, tekočine ali poltrden material. Zbirka gnoja se imenuje absces, ki ni cista. Cisto bo morda treba kirurško odstraniti, vendar je to odvisno od njene vrste in lokacije.
A cyst is a closed sac, having a distinct envelope and division compared with the nearby tissue. Hence, it is a cluster of cells that has grouped together to form a sac (like the manner in which water molecules group together to form a bubble); however, the distinguishing aspect of a cyst is that the cells forming the "shell" of such a sac are distinctly abnormal (in both appearance and behaviour) when compared with all surrounding cells for that given location. A cyst may contain air, fluids, or semi-solid material. A collection of pus is called an abscess, not a cyst. Once formed, a cyst may resolve on its own. When a cyst fails to resolve, it may need to be removed surgically, but that would depend upon its type and location.
