Description
This is a short length of small intestine showing a shallow ulcer with fairly sharply defined edges
and with an irregular outline which runs predominantly transversely. The small intestine is
deformed in a hour-glass fashion at this point. There is some scarring apparent in the submucosa
but the serosa appears intact.
History
This woman presented at the age of 51 with subacute intestinal obstruction; the patient
had been treated with hydrochlorthiazide and potassium chloride. It is assumed that the irritant
effects of a potassium chloride tablet were responsible for the lesion.
