Gastrointestinal bleeding caused by jejunal angiosarcoma: A case report

Figure 1 Capsule endoscopy results. The total capsule operation time was 12 h and 59 min. The time of the capsule endoscopy transit in the esophagus, stomach, and small bowel was 2 min 10 s, 11 min 10 s, and 6 h 35 min, respectively. The results show that there was an ulcerated eminence lesion associated with bleeding over periods of 3 h 18 min to 3 h 23 min.

Figure 2 Positron emission computed tomography/ computed tomographic scan. A: A soft tissue nodule located in the right middle lobe of the lung, about 1.3 cm × 1.0 cm in size, with multiple burrs at the edges and abnormal concentration of tracer; B: Partial small intestinal wall thickness, and abnormal concentration of tracer; C: Bilateral nodular hyperplasia of the adrenal glands, and abnormal concentration of tracer, especially on the right; D: The sacral bone with uneven density, and abnormal concentration of tracer.

Figure 3 A mass approximately 3. 4 cm × 6.0 cm in size was found in the small intestine and partial small bowel (14 cm long) was removed.

Figure 4 Microscopic examination and immunohistochemistry results. A-C: Tumor blood vessels were abundant, with the tumor cells surrounding them (hematoxylin and eosin staining; × 100, × 200, and × 400, respectively); D-I: The tumor cells were positive for CD30, CD31, CD34, VEGR, Fli-1, and FVIII (Immunohistochemical staining; × 200).
