Description
The cut surface of the kidney shows numerous cysts up to 3.0 to 4.0 mm in the papillae. The kidney
is somewhat smaller than normal and the outer surface shows numerous healing scars; there appears
to be an occasional small cyst present although this is unusual in this condition.
History
This was an incidental finding in a hypertensive woman who died from a ruptured myocardial
infarct. This condition is said to be more common in men than in women and it usually appears in late
middle-age. It may be associated with small renal calculi. The cysts are lined by columnar or cuboidal
cells; the cause is unknown.
