Primary adenocarcinoma of the jejunum is rare. From the literature it becomes eyident that any significant number of these tumors must be gathered from a large clinic over a considerable number of years. However, both of the patients in the cases presented here were operated on within a twomonth period of time. Up to 1929 at the Mayo Clinic there were 55 cases of carcinoma of the small intestine compared to 4,597 of the large intestine and rectum together and 4,335 of the stomach.1 One-fourth of these carcinomas of the small intestine were in the jejunum. This represents only 0.06% of the carcinomas of the entire gastrointestinal tract. This figure agrees with another series of cases.2
The average duration of symptoms before diagnosis is 14 months. General weakness, loss of weight, fatigue, and anemia constitute the earlier symptoms. The liquid character of the feces in the small intestine
