ABSTRACT
We report a case of primary appendiceal cancer that metastasized to the ureter. The patient was a 51-year-old woman who complained of persistent left back pain and right lower abdominal pain. After a detailed examination she was diagnosed to have cancer of the appendix, multiple liver metastases, and left hydronephrosis. Since an obstruction of the ileocecum was obvious, she underwent an ileocecal resection and a resection of the spindle-shaped tumor invading the left ureter. Lymph node metastases were found at the root of the superior mesenteric artery. The spindle-shaped tumor was considered to be due to invasion of the appendiceal cancer to the left ureter. The patient died 5 months postoperatively.

We report the rare case of a gallbladder cyst arising from the foregut remnants. A 36-year-old woman was referred to our hospital after screening ultrasonography (US) detected a tumor in the gallbladder. On admission, she was well and her blood analyses were all normal. US showed a cystic mass with internal high-echoic lesions, and computed tomography (CT) demonstrated a protruding tumor with slight enhancement in the gallbladder. Angiography provided no additional information; however, sequential CT-arteriography (CTA) clearly demonstrated that this tumor was a cystic lesion. Surgical exploration was performed, first because of the difficulty in establishing a definite diagnosis, and also because the patient wanted the tumor removed. The resected specimen contained a unilocular cystic tumor that looked like a submucosal tumor. Histologically, the wall of the cyst was lined by ciliated stratified columnar epithelium with interspersed goblet cells and underlying smooth muscle fibers. The mass was finally diagnosed as a congenital ciliated foregut cyst of the gallbladder. Cysts of the gallbladder are uncommon and the majority are acquired. To our knowledge, this represents only the fourth report of a ciliated foregut cyst of the gallbladder in the literature. Although rare, an awareness of this entity could allow a preoperative diagnosis to be made, whereby surgical exploration may be avoided. CT-A is a very useful diagnostic tool, especially when the nature of the tumor presents a difficult differential diagnosis.

We report an extremely rare case of a gastric duplication cyst together with an aberrant pancreatic ductal system, which communicated with the stomach rather than the pancreatic ductal system with no evidence of pancreatitis. A 46-year-old woman developed severe abdominal pain after a 10-year history of occasional mild abdominal pain. Upper gastrointestinal barium radiography showed a rigidity of the stomach wall, and gastroscopy revealed a fistula orifice at a greater curvature of the gastric body. Subsequent endoscopic suction of mucous secretion from within the fistula provided immediate pain relief. Abdominal computed tomography and ultrasonography showed a cystic mass contiguous with the stomach wall. Surgical exploration revealed an uncommon anomaly of a gastric duplication cyst with the aberrant pancreatic lobe. The patient made an uneventful recovery and remains well 4 years after surgery. We also herein review ten other similar cases of this uncommon congenital anomaly reported in the literature.
