Torsion of an appendix epiploica present at the vermiform appendix: a rare cause of acute abdomen.

An extremely rare case of torsion of an appendix epiploica attached to the vermiform appendix is reported in a 57-year-old male who presented with acute abdominal pain and tender right inguinal fossa. An infarcted appendix epiploica was seen attached near the tip of an otherwise unremarkable vermiform appendix through a narrow stalk. The histological examination revealed lobulated fibrofatty tissue showing congestion, acute inflammation and fat necrosis. The appendix was otherwise unremarkable.
