This 14 year old girl had been home from school with abdominal pains and vomiting for 2 days. The pain shifted to her right "groin" and her local doctor performed an emergency operation late at night.
The specimen consists of a 9 cm long markedly swollen, congested and haemorrhagic appendix with attached fatty mesentery. Part of the serosal surface of the organ is covered by a thin layer of fibrinous exudate. The lumen contains inspissated faecal matter. Ill-defined, pale areas on the serosal surface of the appendix are due to necrosis.
