The histopathological features of the residual cyst are similar to those described above for conventional radicular cysts. However, because the cause of the cyst has been removed, residual cysts may progressively become less inflamed so that eventually the cyst wall is composed of uninflamed collagenous fibrous tissue (Figures 3.11 and 3.13). The epithelial lining may be thin and regular and indistinguishable from a developmental cyst, such as a dentigerous cyst or lateral periodontal cyst. In these cases, it is important to establish the relationship of the lesion to the teeth and recall that a residual cyst must arise at a site of an extracted tooth.
