A case report of anaplastic carcinoma of the pancreas with remarkable intraductal tumor growth into the main pancreatic duct

We herein report a case of anaplastic carcinoma of the pancreas with remarkable intraductal tumor growth into the main pancreatic duct.A 76-year-old male was referred to our hospital for treatment of a pancreatic tumor.Preoperative examinations revealed a poorly defined tumor in the main pancreatic duct in the body of the pancreas,accompanied with severe dilatation of the main pancreatic duct,which was diagnosed as an intraductal papillary-mucinous neoplasm.We performed distal pancreatectomy and splenectomy.The pathological examination revealed that the tumor consisted of a mixture of anaplastic carcinoma(giant cell type)and adenocarcinoma in the pancreas.There was a papillary projecting tumor composed of anaplastic carcinoma in the dilated main pancreatic duct.The patient is now receiving chemotherapy because liver metastasis was detected 12 mo after surgery.In this case,we could observe a remarkable intraductal tumor growth into the main pancreatic duct.We also discuss the pathogenesis and characteristics of this rare tumor with specific tumor growth.     

Choledochal cyst and benign stenosis of the main pancreatic duct

We report here the first case of choledochal cyst associated with a benign stenosis of the cephalic part of the main pancreatic duct. The pancreatic ductal stenosis was associated with a protein plug located upstream of the stenosis. Preoperatively, it was not possible to rule out a localized intraductal pancreatic tumor, and a pylorus-preserving pancreaticoduodenectomy was performed. This association has not been described previously, and gives new insights into the pathogenesis of acute pancreatitis associated with choledochal cyst.     

Lymphoepithelial cyst in the pancreas: A case report

A case of lymphoepithelial cyst in the pancreas was reported. A 64-year-old man without any specific compalints was found to have a cystic lesion in the anterior portion of the pancreas, as revealed by ultrasonography of the abdomen at an annual medical examination in 1988. This was dissected easily from the pancreas. Histologically, it was diagnosed to be a benign lymphoepithelial cyst in the pancreas. Cysts of this type are rare, and their histogenesis is also not well understood.     

Primary leiomyoma of the head of pancreas. A case report

Pancreatic leiomyoma is rare. We report a new case in a 52-year old man. A tumor of the pancreatic head was diagnosed after a primary diabetic decompensation. No precise diagnosis was obtained with additional tests. Although the condition appeared to be benign, a diagnostic and therapeutic Whipple procedure was performed.     

Ruptured cerebral hydatid cyst: a case report

In this report we describe a case of cerebral hydatid cyst which ruptured into the subarachnoid space and suggest points which help in the preoperative diagnosis.     

Solitary subcutaneous hydatid cyst: a case report

In the absence of hepatic and pulmonary involvement, hydatid disease of other organs is extremely rare. In this paper, we report on a patient who had a solitary subcutaneous hydatid cyst in the submandibular region.     

Giant hepatic hydatid cyst： A case report

Large type 1 cysts are prone to perforation. Furthermore, insufficient drainage with subsequent abscess is a frequent problem of large cysts. We report here a case of a 19-year old man who was admitted to the hospital with pain in the right upper quadrant and epigastric region. An asymmetrical right upper quadrant enlargement was detected on physical examination. Ultrasonography and computerized tomography revealed a type 1 giant hydatid cyst in the right hepatic lobe, measuring 16 cm in diameter. During operation, partial cystectomy and drainage were done. The large dead space was obliterated by the ‘sandwich’ method. Omentum and gelatin sponges were used to fill the cavity. The postoperative period was uneventful and the patient was discharged on the 5th postoperative day.     

Primary hydatid disease of the pancreas

A case of primary hydatid disease of the pancreas is presented in a patient operated on for an adrenal mass. Computed tomographic findings, such as rounded cystic lesion with curvilinear calcification, may allow the diagnosis to be made in the appropriate clinical setting. The diagnosis was confirmed at surgery.     

Alveolar hydatid cyst with lung metastasis: a case report.

Alveolar hydatid disease is a serious and often fatal condition caused by infection with the metacestode form of echinococcus multilocularis. Liver involvement is seen in 90% of the cases. The parasite develops within the liver as a rapid invasive pseudomalignant growth and may make distant metastasis. We present the case of a 37 year old woman admitted to our gastroenterology department with obstructive jaundice and then diagnosed as alveolar hydatid cyst with lung metastasis. This case is presented due to its rare prevalence.     

Recurred hydatid cyst of the thyroid: a case report

A 21-year-old patient underwent surgery in 1987 for hydatid cyst of segment VIII of the liver. Six years later, the patient developed a cold thyroid nodule. During the thyroid operation, needle aspiration and cytology study confirmed the diagnosis of hydatid cyst. Resection of the prominent dome was performed. In 1996, the patient developed cervical recurrence. Pericytectomy was attempted and during the procedure a wound of the subclavian artery required sternoclavicular disarticulation. Hydatid cyst of the thyroid gland is rare, but should be considered in patients living in endemic zones who develop an anterior neck tumor. Cystectomy, isthmolobectomy or sub-total thyroidectomy may be indicated. Resection of the prominent dome may be required in the event of recurrence.     

Thoracic duct cyst of the neck: a case report.

A thoracic duct cyst was excised from the left side of the neck of a 63-year-old woman. It was 6.5cm in length and 3.5cm in width, and was located behind the common carotid artery and jugular vein. The proximal portion of the thoracic duct with a narrowed lumen was in direct contact with the lateral surface of the cyst and the venous angle. The lower end of the cyst extended into the mediastinum to immediately above the aortic arch; the inferior portion of the thoracic duct descended from the bottom of the cyst into the mediastinum behind the aorta. The cyst was unilocular with a fluid content high in triglyceride (3350mg/dl). Its wall was muscular and permeated with lymphatic vessels.
