  • Abstract
  • Look Inside

 A 25-year-old female visited our outpatient clinic, complaining of intermittent upper abdominal pain increasing especially after meal intake. Three months later, the patient was admitted to our hospital because bouts of the pain had become more frequent. A mobile tumor was palpated in the left upper abdomen on admission. Abdominal sonographic study showed a target sign in the small intestine. The roentogenography with contrast media of the small intestine revealed a pedunculated tumor with nodular and granular surface, accompanied with local dilatation of the jejunum caused by obstruction. The endoscopic views during the surgical operation also disclosed a pedunculated tumor with nodularity and granularity, showing the same color as the surrounding mucosa. The tumor had neither erosion nor ulceration on its surface. Partial jejunectomy was performed. The resected tumor measured 33×30×25 mm in size. The pathological diagnosis of the tumor was Peutz-Jeghers type polyp. Finally, the patient was diagnosed as a case of jejunal Peutz-Jeghers type polyp because of the lack of any hereditary factor and the abnormal mucocutaneus pigmentation.
