Incidental splenosis discovered during robotic assisted radical prostatectomy: A case report

Abstract

Splenosis refers to the benign heterotopic auto transplantation of splenic tissue that most commonly arises following traumatic rupture of the spleen. It is most often associated with traumatic rupture of the spleen. While often asymptomatic, splenosis can mimic malignancy and may lead to unnecessary biopsy, chemotherapy, and surgery. This case report highlights an instance of splenosis discovered incidentally during robotic assisted radical prostatectomy. Splenules were sent for frozen section due to concern for malignancy. Retrospective analysis of imaging obtained prior to the procedure was consistent with splenosis.
