Lymphangiomas are rare congenital benign tumors arising from the lymphatic system, and are mostly encountered in the neck and axillary regions of pediatric patients (95%). Lymphangioma of the pancreas is extremely rare accounting for less than 1% of these tumors. We report here on a case of pancreatic cystic lymphangioma. A 54-year-old woman presented with intermittent postprandial abdominal discomfort and radiating back pain. Abdominal computed tomography scan revealed 8 x 6.5 cm hypodense cystic mass arising from the tail of the pancreas without septa or solid component. The initial impression was a pancreatic pseudocyst. The patient underwent distal pancreatectomy with splenectomy. The histopathologic and immunohistochemical study helped make the diagnosis of a pancreatic cystic lymphangioma. Herein, we report a case of pancreatic cystic lymphangioma mimicking pancreatic pseudocyst and review the relevant medical literature.

Primary sarcomas of the pancreas are extremely rare, accounting for 0.1% of malignant pancreatic (non-islet) neoplasms. Pancreatic leiomyosarcoma is a highly aggressive malignancy that spreads in a similar manner to gastric leiomyosarcoma, i.e., by adjacent organ invasion, hematogenous spread, and lymph node metastasis. These tumors are large at the time of diagnosis and are usually found at an advanced stage. We report a case of a 70-year-old female with intermittent right upper quadrant abdominal discomfort. Radiological, histopathological, and immunohistochemical studies revealed the tumor to be a primary leiomyosarcoma of the pancreas. Herein, we describe a patient with a primary leiomyosarcoma of the pancreas who presented with clinical and radiological findings indicative of a mass in the pancreatic head.

PURPOSE: To analyze the outcomes of laparoscopic liver resection compared with open liver resection in patients with hepatocellular carcinoma (HCC). METHODS: Between July 2005 and December 2009, 26 consecutive patients with HCC underwent a pure laparoscopic liver resection, and data from this group (laparoscopic liver resection group, L-group) were compared with a retrospective control group of 29 patients who underwent open liver resection for HCC (open liver resection group, O-group) during the same period. The two groups were matched in terms of demographic data, tumor size, degree of liver cirrhosis, American Society of Anesthesiology score, type of resection, and tumor location. RESULTS: Median operation time and the amount of intraoperative packed red blood cell transfusion in the L-group were 147.5 minutes and 0.35 units, respectively. The L-group revealed a shorter operation time (147.5 vs. 220.0 minutes, P = 0.031) than the O-group. No difference in perioperative morbidity or mortality rates was observed (3.8, 0 vs. 24.1%, 0%; P = 0.054, non-specific, respectively); the L-group was associated with a shorter hospital stay than the O-group (11.08 vs. 16.07 days, P = 0.034). After a mean follow-up of 23.9 months (range, 0.7 to 59.4 months), the 1-year disease-free survival rate was 84.6% in the L-group and 82.8% in the O-group (P = 0.673). CONCLUSION: Laparoscopic liver resection for HCC is feasible and safe in selected patients and can produce good surgical results with a shorter postoperative hospital stay and similar outcomes in terms of perioperative morbidity, mortality, and disease-free survival than open resection.

PURPOSE: Surgery remains the only curative option for patients with extrahepatic bile duct cancer (EHBD Ca). But, long-term survival is typically not good because of the advanced stage of disease at the time of diagnosis and frequent disease recurrence after surgical resection. The purpose of this study was to evaluate factors that influence survival and recurrence after surgical resection of EHBD Ca. METHODS: A retrospective analysis of 113 patients who had received surgical resection for EHBD Ca between 2004 and 2009 was done. We investigated histopathological features, and survival and recurrence rates, and evaluated prognostic factors affecting survival and disease recurrence after surgical resection. RESULTS: Overall survival rates for 1, 3 and 5 years were 73.2%, 42.8%, and 36.0% respectively. In univariate analysis, prognostic factors influencing survival were histologic differentiation, T stage, lymph node (LN) metastasis, TNM stage, perineural invasion (PNI), lymphovascular invasion (LVI) and resection margin state. Among them, LN metastasis, PNI and resection margin state were found to be independent prognostic factors for overall survival in multivariate analysis. Recurrence occurred in 44 patients (48.9%) and disease-free survival rates were 50.6% at 1 year and 38.3% at 3 year. Univariate analysis revealed that histologic differentiation, T stage, LN metastasis, TNM stage, PNI and LVI were significantly associated with recurrence. In multivariate analysis, only LN metastasis was found to be a significant independent predictor of recurrence. CONCLUSION: LN metastasis, PNI and positive resection margin were significant prognostic factors affecting survival. LN metastasis was found to be a significant independent predictor of recurrence in surgical resection of EHBD Ca.

PURPOSE: Bone is the most common site of metastasis from breast cancer. An abnormal bone scan finding, however, is not specific in differentiation of bone metastasis from traumatic or inflammatory bone diseases. The purpose of this study was to identify clinical findings that could help evaluate the etiology of solitary costal hot spots on a bone scan. METHODS: The study included 32 patients (all women, mean age 51+/-1 years) showing solitary costal hot spots on postoperative bone scans performed between January 1998 and December 2002. In order to classify the etiology of solitary costal hot spots as non-malignant or malignant, all available clinical, scintigraphic, laboratory and other radiographic examinations were taken into consideration. RESULTS: The mean follow-up period was 42.5 months. Among 32 hot spots, 7 (21.8%) were metastatic, and the remaining 25 (78.2%) non-malignant. The mean period of first detection after operation was 17.0+/-16.3 months in the metastatic and 26.0+/-21.3 months in the non-malignant groups. The metastatic group was significantly associated with advanced breast cancer. In the localization of rib lesion, 20 (62.5%) of the solitary costal hot spots were in the anterior arc, 5 (15.6%) in the lateral arc and 7 (21.9%) in the posterior arc. In the group with a location at the anterior arc, 16 (80%) were non-malignant, whereas 4 (20%) were malignant. In those localized at the anterior arc, 12 (60%) were on ipsilateral and 8 (28%) were on contralateral. The difference between the hot spots in the ipsilateral and contralateral locations was not significant. The carcinoembryonic antigen (CEA) and CA15-3 were elevated: in 5 (51%) and 3 (43%) patients with metastatic spots, and in 4 (16%) and 1 (4%) patient with non-malignant lesions, which were significantly different. CONCLUSION: It was found that an advanced state of primary breast cancer and the increase of tumor markers (CEA and CA15-3) were the significant factors for the direction of the nature of solitary costal hot spots on postoperative bone scans in patients with breast cancer.

Hamartoma of the spleen is a rare benign lesion and the pathogenesis of this is not completely understood. It is usually incidentally discovered during an operation or autopsy. Since the first report in 1861 by Rokitansky, less than 150 cases of splenic hamartoma have been documented in the literature to date. The majority of the patients with this tumor are asymptomatic. However, a few of these lesions are associated with clinical features such as hypersplenism, cirrhosis of the liver and spontaneous splenic rupture. Because there are no specific symptoms, tumor markers or radiologic results, it is usually difficult to make a diagnosis before surgery and the specimen pathology. We report here on three cases of splenic hamartoma (a 33-year-old man associated with thrombocytopenia, a 29-year-old woman with a 6-month history of left upper quadrant abdominal pain and a 43-year-old man with synchronous hepatocellular carcinoma) and we review the relevant literature.

Undifferentiated carcinoma with osteoclast-like giant cells is a rare neoplasm of the exocrine pancreas. Some similar cases have been reported, but the histogenesis of these tumors varies and is controversial. We report here on a case of undifferentiated carcinoma of the pancreas with osteoclast-like giant cells. A 77-year old woman presented with abdominal pain and anorexia. Abdominal computed tomography and magnetic resonance imaging showed an approximately 10 x 5 cm highly attenuated mass arising from the tail of the pancreas and invading the spleen and adjacent bowel loop. The initial impression was a malignant endocrine tumor or solid-pseudopapillary tumor of the pancreas. The patient underwent a distal pancreatectomy with splenectomy and left hemicolectomy. The histopathology and immunohistochemistry helped make the diagnosis that of an undifferentiated carcinoma with osteoclast-like giant cells of the pancreas.
