Cysta (Cyst) är en sluten påse. En cysta (cyst) kan innehålla luft, vätska eller halvfast material. En ansamling av pus kallas en abscess och är inte en cysta. Cystan kan behöva avlägsnas kirurgiskt, men det beror på dess typ och placering.
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.
Ganglion cyst ― Asymtomatiska klumpar som uppstår plötsligt mellan lederna. Om diagnosen ganglioncysta bekräftas, kan problemet lösas genom att trycka hårt på knölen för att spränga cystan inuti.
Mucocele ― Det ser ut som en mjuk bula på läpparna utan några symtom.
