Sist (Cyst) is 'n geslote sak. sist (cyst) kan lug, vloeistowwe of halfvaste materiaal bevat. 'n Versameling etter word 'n abses genoem, wat nie 'n sist is nie. Die siste moet dalk chirurgies verwyder word, maar dit sal afhang van die tipe en ligging daarvan.
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 ― Asimptomatiese knoppe wat skielik tussen gewrigte voorkom. As die diagnose van ganglion sist bevestig word, kan die probleem opgelos word deur die knop hard te druk om die siste binne te bars.
Mucocele ― Dit verskyn soos 'n sagte stamp op die lippe sonder enige simptome.
