Cyst o se taga tapuni. Cyst e ono aofia ai le ea, sua, po'o mea fa'ama'oti. O le fa'amaumauga o le pusi e taʻua o le abscess, e le o se cyst. Atonu e mana'omia ona aveese le cyst, ae e fa'alagolago i lona ituaiga ma le nofoaga.
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.
