Since the recognition of this entity in 1829 by Andral1 and the first splenectomy for this condition in 1867 by Pean,2 sporadic reports have appeared in the literature. By 1944 Harmer and Chalmers3 had gathered 162 cases, and this number was increased to 265 by Fowler's collective review4 in 1953. At the present time 421 cases have been summarized in our review of the literature.5 Not more than three cases have been reported by any individual investigator in the past 20 years,5-21 and it is interesting that only four splenic cysts were found in 800 surgically removed specimens at the Mayo Clinic over a 36-year period.22
