For information about the wide variety of Jewish views on what happens after death, see Simcha Paull Raphael's book, Jewish Views of the Afterlife. Raphael, a Reconstructionist rabbi, takes a historical approach to life-after-death theories, exploring the views that predominated in each era of Jewish history.
Preauricular sinus and cyst. A preauricular sinus (also known as a congenital auricular fistula, a congenital preauricular fistula, a Geswein hole, an ear pit, or a preauricular cyst) is a common congenital malformation characterized by a nodule, dent or dimple located anywhere adjacent to the external ear.
A cyst is a sac that can form anywhere in the body and is filled with air or some type of fluid. Most of these are completely benign and noncancerous. Perineural cysts are those that form in the sacrum, or the base of the spine.
