Pulmonary sequestration and congenital cystic adenomatoid malformation are two infrequent congenital pulmonary diseases and the combination of these two entities is rare. We had experienced a 3 week old male patient with a pulmonary mass, who had been sufyerring from tachypnea and chest wall retraction after birth. The pulmonary mass was suspected as a congenital cystic adenomat id malformation by chest CT. And therefore, we performed urgent operation via standard thoracotomy incision. Upon a thoracotomy, there was an extrapleural mass with anomalous blood supply near the posterior diaphragm and multiple cystic lesions in right lower lobe. The two anomalous arteries arising from the thoracic aorta and one vein draining into the azygos vein were ligated. and then the extrapleural mass was removed and a right lower lobectomy was performed. Final histologic diagnosis was congenital cystic adenomatoid malformation associated with extralobar pulmonary sequestration. The patient was discharged without any problem.

Chiari's networks are present in 1.5% to 4% of the population. They are a congenital disease characterized by a remnant of the right valve of sinus venosus and rarely have clinical significance. Chiari's network, as the name implies, has network-like shape, but there are other forms of appearance. We have experienced a case of a 60-year-old woman who had a cystic mass on the right atrium. Surgical treatment was performed forthe mass removal and differential diagnosis of the mass. There was no evidence of other tumor, but Chiari's network. As cystic form of Chiari's network have not been reported before, it is the first report of cystic form of Chiari's network.

A 48 year old woman was diagnosed with a huge cystic mass in her abdominal cavity. She complained of significant abdominal discomfort due to the mass. The abdominal computed tomography revealed a giant multi-lobulated mass, measuring $26{\times}12$ cm in size, adjacent to the lesser curvature of the stomach. In the operation field, the mass was found to originate from the lesser omentum, including the right and left gastric vessels and the vagus nerves, and to invade the lesser curvature of the stomach. For curative resection, distal subtotal gastrectomy with mass excision followed by gastroduodenostomy were performed. This mass was pathologically diagnosed to be a mesenteric cystic lymphangioma; in fact, the largest ever reported. The patient had no complications during the postoperative period and was discharged from the hospital on the seventh day after surgery.

Gangliogliomas could be found anywhere throughout the central nervous system and mainly affect children and young adults during the first three decades of life. Cerebellar gangliogliomas may be rarely found, especially in old ages. Here, we present a case of ganglioglioma of the cerebellum in an old patient. The cystic cerebellar mass was associated with calcifications, intratumoral hemorrhage without ng edema. When a cystic cerebellar mass is associated with calcifications and intratumoral hemorrhage, ganglioglioma should be included in differential diagnosis. Gangliogliomas usually have good prognoses. Radiation therapy should be deferred even in subtotally removed cases.

Adrenal venous malformation is an uncommon disease. We report a case of an incidentally diagnosed adrenal cystic mass during an evaluation for gastritis in a child. A 14-year-old girl admitted to our pediatric department for epigastric pain. After the gastroscopy, she was diagnosed with hemorrhagic gastritis. A 5.5 cm-sized cystic mass was incidentally found adjacent to her left adrenal gland during an ultrasound examination for evaluating her abdominal symptoms. She underwent laparoscopic surgery for the diagnosis and treatment of this cystic mass, which was confirmed to be venous malformation at pathologic diagnosis.

Purpose: The epidermal cyst is a very common skin lesion which usually occurs in the hairy regions. They are generally small but rarely reach more than 5 cm in diameter. We present a patient with a giant epidermal cyst on buttock area. Methods: A 50-year-old man with a slowly enlarging, huge mass in his left buttock was examined. There was no history of trauma in this area. Physical examination revealed a soft, nontender, $15{\times}15cm$-sized mass in his left buttock. T1-weighted magnetic resonance images demonstrated a well-circumscribed, multilocular cystic lesion with homogeneous, slightly high signal intensity. On T2-weighted images the lesion had wide areas of high signal intensity. The mass was totally excised. Results: A histopathological finding revealed that the cystic wall was lined with whole layers of stratified squamous epithelium. Keratin layers from the surface of the epithelium were seen to be sloughing into the cystic lumen. Multinucleted giant cells were found outside the cystic wall. Conclusion: Herein we report a rare case of giant epidermal cyst occurring on the buttock.

A 50-year-old male presented gradually growing pancreatic body mass. An abdominal computed tomography showed a 9.9-cm mass, larger than the 8.9-cm mass one year ago. As the patient did not have complaints for any symptomatic problems, the gastroenterologist decided to check it with regular follow-up. However, as the tumor grew faster than expected, the patient was recommended for surgical resection. Laparoscopic pylorus preserving pancreaticoduodenectomy was done. Since the tumor abutted to the superior mesenteric vein and the portal vein, wedge resection of vessel was inevitable. Pathology was serous cystadenoma. The patient was discharged without postoperative complications. Herein, we report this case with asymptomatic large serous cystic neoplasm treated by laparoscopic approach. The appropriateness of current guidelines for surgery in serous cystic neoplasm is also discussed.

A 61-year-old male who complained of right upper quadrant pain was referred to the authors for evaluation after his computed tomography suggested biliary adenocarcinoma. The lesion consisted of multiple cysts with papillary mass and peri-ampullay mass. The patient underwent an operation due to a clinical suspicion of biliary cystadenocarcinoma, but the pathology confirmed biliary papillomatosis (BP) after diagnosing intrahepatic papillary neoplasm with high-grade dysplasia and invasive adenocarcinoma with papillary neoplasm from the distal common bile duct to the duodenum. BP is a disease characterized by multiple papillary masses. Its cause has yet to be discovered. It commonly manifests as bile duct dilation but rarely as a ductal cystic change. Under computed tomography or magnetic resonance imaging, both the BP and the cystic neoplasm can show bile duct dilation and a papillary mass, which makes their differential diagnosis difficult. A confirmative diagnosis can be made through a pathologic examination. BP is classified as a benign disease that can become malignant and may recur, though rarely. Its treatment of choice is surgical resection. Laser ablation or photodynamic therapy can be used for unresectable lesions. In the case featured in this paper, biliary papillomatosis was difficult to differentiate from cystic adenocarcinoma due to diffusely scattered multiple large cystic lesions in the liver, and it was histologically confirmed to have become malignant with cystic duct dilation after the operation. This case is reported herein with a literature review.

Retroperitoneal cystic lymphangiomas are benign, extremely rare tumors. Although surgical resection is the treatment of choice, sclerotherapy should be considered initially. A 9-year-old boy was admitted due do worsening abdominal pain of 4 days duration. Serial complete blood counts revealed a hemoglobin level of 12.8 g/dL on admission to 10.6 g/dL on hospital day 3. An abdominal computed tomography (CT) scan showed a large, lobulated, septated, retroperitoneal cystic mass ($10{\times}9.5{\times}5cm$) in the left anterior pararenal space with intracystic hemorrhage surrounding the inferior mesenteric vein (IMV). Because of the high operative risk, we performed a tubogram of the cystic mass, percutaneous catheter drainage (PCD), and ethanol sclerotherapy. The follow-up abdominal CT scan showed that the cystic mass had decreased in size. He is well without relapse of the retroperitoneal cystic mass for 13 months after discharge. Sclerotherapy with PCD should be considered as initial therapy for patients with retroperitoneal cystic lymphangiomas at high surgical risk.
