Peritoneal Deciduosis: A Case Report.

ABSTRACT

Peritoneal deciduosis is a rare incidental finding on caesarean section.This is a self- limited metaplastic change of submesothelial mesenchymal cells during pregnancy. We report a case of diffuse peritoneal ectopic decidual reaction discovered during caesarean section as pale whitish nodules simulating tubercles. Histology showed omentum studded with nodular groups of decidual cells with transition to spindle cells resembling myofibroblasts.
