Subsequently, anatomists da Carpi2 and Vesalius3 formally described the appendix in the mid-1500s. Soon thereafter, in 1554, Fernel described the first recorded case of disease of this organ: a 7-year-old girl with diarrhea was administered treatment with a large quince fruit, which obstructed the appendiceal lumen after it was ingested.4 She developed severe abdominal pain and died. Autopsy showed the quince fruit obstructing the appendiceal lumen, with resultant appendiceal necrosis and perforation, thereby resulting in the first description, postmortem, of what would later be known as “appendicitis.”
