[Spontaneous splenic rupture due to amyloidosis].

Splenic rupture is frequently produced due to traumatic mechanisms, being referred to as spontaneous or pathological when there is no history of trauma or there is an underlying splenic disease. Spontaneous splenic rupture due to amyloid deposits is a very uncommon cause of surgical acute abdomen. The patient in this case is a woman admitted with acute abdomen secondary to spontaneous splenic rupture, whose final diagnosis was primary amyloidosis.
