ACUTE APPENDICITIS

ACUTE APPENDICITIS

Clinical History

A 42 year old male pesented with a three day history of central abdominal pain, nausea and a slight fever. The pain progressed to the right iliac fossa. Rebound tenderness and guarding were present on examination.

Pathology

The specimen consists of an irregular mass of oedematous fatty tissue 7 cm in maximum diameter, with some patchy, subserosal haemorrhage. Protruding from the upper end of the mass is a 3 cm length of swollen appendix, the surface of which is covered by a layer of fibrous exudate. A small amount of exudate is also seen on the surface of the adjacent fatty tissue. This is acute appendicitis.
