Myxoma is the most common type of primary cardiac tumors, accounting for 50%-80% of them. Cardiac myxomas are difficult to detect due to the lack of specific signs and symptoms and even benign tumors can cause serious consequences. Cardiac failure, atrio-ventricular valve obstruction or the embolization phenomenon can quietly occur in patients with cardiac myxomas. Here, we report three extraordinary cases, each of which vary in the first symptom. One case involved a 66-year-old man who had no underlying heart disease but suddenly developed chest tightness and got out of breath after exercising. One case was a 36-year-old young woman with a two-year history of low blood pressure but suddenly suffered a stroke. The third case was a 42-year-old middle-aged woman who accidentally discovered a cardiac myxoma during the diagnosis and treatment of acute pancreatitis. Echocardiography revealed huge masses floating in their atriums. Under general anesthesia, all the patients underwent open-heart surgery and hematoxylin and eosinÀstained sections of the samples confirmed myxomas. Although most patients with cardiac myxomas lack of specific systemic symptoms, typical myxomas are relatively easy to diagnose. There are currently no effective medical therapeutic to inhibit tumor growth and surgical resection is the mainstay of treatment, which prevents a dreaded complication resulted from systemic and pulmonary embolisms.

Background: Tuberculosis (TB) is a major health problem worldwide. Even in highly prevalent countries, primary gastroduodenal tuberculosis is a rare manifestation of extrapulmonary tuberculosis. In recent years, as the incidence of tuberculosis has increased year by year, the occur of gastroduodenal tuberculosis has also increased. Endoscopy is an important tool for diagnosing gastroduodenal tuberculosis. The performance of gastroduodenal tuberculosis under endoscopy is often non-specific, which may imitate other benign or malignant gastroduodenal diseases. Diagnosis of gastroduodenal tuberculosis relies on a combination of endoscopy and guided biopsy. Case presentation: Here, we report a rare and interesting case of gastroduodenal tuberculosis with acute pancreatitis. The case initially mimicked gastroduodenal ulcers in morphology and appeared in a middle-aged person with normal immunity but with prolonged fever and abdominal pain. The disease was diagnosed through endoscopy and guided biopsy, and it responded well to antituberculosis drugs. Conclusions: Clinicians must remember that even in the absence of immunodeficiency, as in this case, tuberculosis can affect any part of the gastrointestinal tract.
