RESUMEN
Gastric conduit reconstruction is the standard choice after esophagectomy. Conduit's vascular supply is of primary importance mainly based on right gastroepiploic vessels. A 57-year-old male with absent right gastroepiploic artery, due to a duodenal bleeding ulcer treated with gastroduodenal artery ligation 10 years ago, was treated for gastroesophageal cancer and required esophagectomy. Surgical merits of this troublesome scenario are highlighted. Previous surgical history is highly important for patients requiring complex surgery as esophagectomy. The use of the stomach as conduit after esophagectomy is always the primary option; however vascular supply of it should not be compromised. Variations are rare and careful planning may overcome obstacles as in this case.
RESUMEN
Introduction. Nontraumatic splenic rupture is a rare event. On the other hand, splenic metastasis is also rare and usually found in the context of disseminated disease. Spontaneous splenic rupture caused by a metastatic deposit has been reported only as case reports. To the best of our knowledge, pancreatic cancer being the primary site has been reported in only a handful of cases. Case Presentation. A case of spontaneous splenic rupture in a 68-year-old male presenting with acute onset left shoulder pain, caused by metastatic pancreatic cancer to the spleen, is presented herein. During the investigation, the patient developed hypovolemic shock due to intra-abdominal hemorrhage, necessitating emergency splenectomy. The patient recovered well and was discharged from the hospital on the 8th postoperative day. Discussion. This study underlines the fact that the spleen is a rare site of metastasis, remaining mostly asymptomatic. However, it can nevertheless prove to be a life-threatening condition. The exact pathophysiological mechanism of splenic rupture due to metastasis still remains unknown, requiring further research. Emergency splenectomy remains the standard of care, and this clinical condition should be considered in the differential diagnosis of cases with acute abdomen and malignant neoplasm history.
RESUMEN
In esophageal cancer, metastatic spread to the lungs is detected in 4-9.7% of cases. During staging investigations, 22% of patients have pulmonary nodules detected on cross-sectional imaging. The purpose of this study is to elucidate the clinical importance of these incidentally found pulmonary nodules, in patients with clinically localized esophageal cancer. A retrospective cohort study was conducted from January 2008 to December 2012 in a tertiary esophagogastric referral center. One-hundred and forty-nine patients were included in the study. All patients underwent dedicated staging followed by neoadjuvant chemotherapy and surgery as indicated. Thirty-three (22.1%) patients had pulmonary nodules found in their preoperative staging. Only three (9%) patients proved to develop metastatic pulmonary disease on follow-up. Interestingly, in all three patients, the nodules were negative on initial 18-fluorodeoxyglucose positron emission tomography. Incidentally found pulmonary nodules in newly diagnosed patients with esophageal cancer during staging investigations are rarely metastases. Such nodules, in isolation, should not preclude patients from radical treatment.

INTRODUCTION: Secondary pancreatic metastasis from other solid organ malignancy is rare and accounts for less than 2% of all pancreatic tumors. The aim of this study is to highlight that colorectal metastatic disease in the pancreas could be in selected cases an indication for surgery rather than for palliative chemotherapy. CASE PRESENTATION: We present a case of a 62-year-old Caucasian female with a history of rectal adenocarcinoma. Four years ago, the patient underwent low anterior resection of the rectosigmoid, post neoadjuvant chemoradiotherapy, with adjuvant chemotherapy. During her follow-up, imaging examinations revealed a lesion in the pancreatic neck with features indicating primary pancreatic cancer. Near-total distal pancreatectomy with en bloc splenectomy was performed. Histopathology revealed metastatic disease compatible with colorectal adenocarcinoma as the primary cancer. Second-line chemotherapy was decided from the institutional tumor board. The patient remains disease free one year later. CONCLUSION: Pancreatic lesions in patients with a history of extrapancreatic malignancy should raise suspicions of metastatic disease. Surgical intervention is a legitimate treatment option for these pancreatic lesions, since they represent solitary disease deposits and of course in the context of multidisciplinary meeting decisions, and after proper and extensive staging investigations.
RESUMEN
The purpose of this study was to assess the oncological outcomes of a large multicenter series of left thoracoabdominal esophagectomies, and compare these to the more widely utilized Ivor-Lewis esophagectomy. With ethics approval and an established study protocol, anonymized data from five centers were merged into a structured database. The study exposure was operative approach (ILE or LTE). The primary outcome measure was time to death. Secondary outcome measures included time to tumor recurrence, positive surgical resection margins, lymph node yield, postoperative death, and hospital length of stay. Cox proportional hazards models provided hazard ratios (HR) with 95% confidence intervals (CI) adjusting for age, pathological tumor stage, tumor grade, lymphovascular invasion, and neoadjuvant treatment. Among 1228 patients (598 ILE; 630 LTE), most (86%) had adenocarcinoma (AC) and were male (81%). Comparing ILE and LTE for AC patients, no difference was seen in terms of time to death (HR 0.904 95%CI 0.749-1.1090) or time to recurrence (HR 0.973 95%CI 0.768-1.232). The risk of a positive resection margin was also similar (OR 1.022 95%CI 0.731-1.429). Median lymph node yield did not differ between approaches (LTE 21; ILE 21; P = 0.426). In-hospital mortality was 2.4%, significantly lower in the LTE group (LTE 1.3%; ILE 3.6%; P = 0.004). Median hospital stay was 11 days in the LTE group and 14 days in the ILE group (P < 0.0001). In conclusion, this is the largest series of left thoracoabdominal esophagectomies to be submitted for publication and the only one to compare two different transthoracic esophagectomy strategies. It demonstrates oncological equivalence between operative approaches but possible short- term advantages to the left thoracoabdominal esophagectomy.

INTRODUCTION: Solitary fibrous tumor is a rare type of mesenchymal, spindle-cell tumor reported mostly in the pleura. Retroperitoneal occurrence is rare and histopathological diagnosis is challenging. CASE PRESENTATION: A 55-year-old woman with nonspecific abdominal pain was found to have a retroperitoneal/pelvic mass adjacent to the upper rectum. The patient underwent surgical resection in clear margins of this pelvic tumor, entering the total mesenteric excision surgical plane. Final histopathology revealed a solitary fibrous tumor and the case is presented herein. DISCUSSION: Solitary fibrous tumor in the retroperitoneum is rarely found in the literature and to the best of our knowledge less than a hundred cases are described so far. Histopathological diagnosis is mostly based on a "patternless pattern" on microscopic examination, which is a storiform arrangement of spindle cells combined with a "hemangiopericytoma-like appearance" and increased vascularity of the lesion. Surgery is the mainstay of treatment and recurrence rates are generally low.
RESUMEN
Introduction. Primary hepatic lymphoma is an unusual malignancy and is very difficult to diagnose promptly. An intrigue case presenting with cholestatic jaundice is reviewed and main disease characteristics are further discussed. Case Report. A 70-year-old male presented with dull right upper quadrant abdominal pain and mild cholestatic jaundice. Initial evaluation revealed mildly elevated liver function tests and normal tumor markers, while imaging with an abdominal CT-scan showed multiple hypodense nodules in both liver lobes. First impression of metastatic deposits from gastrointestinal origin was not confirmed by endoscopic means. After CT-guided biopsy, primary diffuse large B-cells non-Hodgkin lymphoma was revealed. Appropriate chemotherapy improved patient's condition markedly. Discussion. Primary hepatic lymphoma is a rare form of extranodal lymphomas, accounting for less than 1% of all extranodal lymphomas in general. In order to define the condition as PHL, liver has to be the only site of lymphoma occurrence or to be involved in a major degree with minimal nonliver disease. Most PHLs are of B-cell origin with large cells as the main cell type.
RESUMEN
INTRODUCTION: Mucinous cystadenoma is the most common of benign neoplasms of the appendix and carcinoid is the most common type of primary malignant lesions of the appendix.We report a rare case of a 57-year-old female with combined mucinous cystadenoma and carcinoid tumor of the appendix.Dual carcinoid and epithelial neoplasia is a rare occurrence in the appendix. CASE REPORT: A 57-year-old Caucasian woman presented after incidentally palpating a mass on her right iliac fossa. Imaging modalities revealed a cystic tumor in the right iliac fossa with a diameter of about 8 cm, originating either from the right ovary or the appendix. She underwent laparoscopic surgical exploration, which revealed appendiceal mucocele and appendicectomy was finally performed as well as excision of a right ovarian cyst. Pathological examination showed acollision tumor consisting of mucinous cystadenoma and carcinoid tumor of the appendix. Because of the size and extension of the carcinoid tumor, which the pathology report revealed, she underwent re-exploration and laparoscopic right colectomy. DISCUSSION: Mucinous cystadenoma is rare, but it is the commonest of benign appendiceal tumours accounting for 0.6% of appendectomy specimens. It can present as appendicitis,mucocele or if the tumour ruptures, as pseudomyxomaperitonei. On the other hand, carcinoid is the most common type of primary malignant lesion of the appendix and 0.3-0.9%of appendectomy specimens, with small predominance in female patients. Rare cases of mucinous cystadenomas of the appendix coexisting with carcinoid tumors were reported before, but in our case it was a collision tumor with no transitional zone between them. Also, the clinical presentation of our patient and the differential diagnosis of ovarian lesions from appendiceal tumors is worth being mentioned.

PURPOSE: The aim of this study was to review the clinical features, diagnostic modalities, treatment options and pathological characteristics of various types of hepatic vascular tumors treated in our Institution over the last 20 years. METHODS: From 1991 to 2011, 761 cases of various hepatic lesions, benign and malignant, were surgically treated in our hospital. Among these, 56 (7.35%) hepatectomy specimens referred to vascular tumors. The records of these patients were retrieved and demographics , tumor characteristics, treatment, and actuarial survival were analyzed. The various therapeutic procedures, postoperative complications, follow-up data and the pre-and postoperative diagnostic difficulties were registered and analyzed. RESULTS: Pathological examination showed: hepatic hemangiomas in 35 (62.5%) patients (80% females), hepatic angiosarcomas in 7 patients (12.5%; males 71.4%), hepatic epithelioid hemangioendotheliomas in 9 (16%; females 50%) and hepatic angiomyolipomas in 5 patients (9%; females 60%). CONCLUSIONS: Vascular tumors of the liver comprise a heterogeneous group of neoplasms, benign, malignant and of intermediate degree of malignant behavior. These lesions can create great diagnostic difficulties, pre- and postoperative considerations, but the correct pathological diagnosis and classification of vascular hepatic tumors are most of the times mandatory in order to choose the proper therapeutic actions.

PURPOSE: Non-epithelial breast neoplasms cover a large spectrum of histopathological entities. The demographics and clinical features are similar to epithelial breast lesions but the diagnosis, prognosis and management options are often very different. METHODS: During 2001-2010, 1362 patients were examined at the Pathology Department of the Aretaieion General Hospital for various breast lesions. All specimens were processed routinely and slides stained with hematoxylin-eosin were re-examined. The patient clinical records were examined for demographics, clinical presentation and therapeutic approach. RESULTS: In 23/1362 cases (1.68%) pathological examination showed non-epithelial lesions: in 12/1362 cases (0.8%) haemangiomas (11 women, one man), in 4 /1362 cases (0.3%) myofibroblastomas (MFB), in 2/1362 cases (0.1%) primary breast non-Hodgkin's lymphoma (NHL), in 3 /1362 cases (0.2%) granular cell tumor (GCT), and in 2/1362 cases (0.1%) angiosarcomas (one developed after radiotherapy for breast cancer). CONCLUSIONS: Non-epithelial primary breast tumors are rare (1.68%) and present significant difficulty in accurate preoperative diagnosis and in certain cases in pathological diagnosis as well, which is necessary for the selection of the appropriate treatment. Avoidance of inappropriate therapies requires a multidisciplinary management approach.

Three cases of peritoneal benign cystic mesotheliomas in women 32-34 years of age and one case of peritoneal malignant mesothelioma in a 47-year-old woman are reported. All cases presented with abdominal discomfort and/or pain and the physical and radiological diagnostic methods showed adnexal tumors. The cystic mesotheliomas developed in the cul-de-sac and the right pelvic sidewall, presented as multiple small cysts or large multilocular cystic mass. The malignant mesothelioma showed extensive infiltration of the omentum the intestinal loops and the surface of the uterus and adnexa, with bilateral hydrosalpinx and ascites. All cases presented histological and immunohistochemical characteristics consistent with tumors of mesothelial origin. No history of asbestos exposure was reported. The correct diagnostic and therapeutic approaches to these neoplasms are discussed.

Rectus sheath hematoma (RSH) is an accumulation of blood in the rectus abdominis muscle sheath, secondary to several conditions which may cause the epigastric vessel rupture or muscular tear, but mostly affecting patients undergoing anticoagulation therapy.We present a rare case of a 67-year-old woman who underwent laparoscopic cholecystectomy and developed RSH on the 12th postoperative day. The patient was under anticoagulation therapy with acenocoumarole due to mitral valve replacement. The bleeding source was an arteriovenous malformation (AVM) rupture as indicated by the angiogram images and it was embolized succefully. The patient was discharged seven days later.
RESUMEN
INTRODUCTION: Liver trauma is a critical condition that requires swift multidisciplinary approach. In complex hepatic injuries perihepatic packing is an established life-saving procedure. The aim of this study is to evaluate and highlight the value of absorbable mesh wrapping of the injured liver, combined with ipsilateral ligation of portal vein branch. CASE PRESENTATION: An 82-year-old patient underwent an open cholocystectomy, for gallbladder empyema. The second postoperative day he was re-operated on due to active hemorrhage. The bleeding was controlled by suturing the bed of the gallbladder fossa. During this maneuver a portal vein branch was torn resulting in a rapidly expanding subcapsular liver hematoma which led to the formation of two deep lacerations on the liver parenchyma. This life-threatening condition was treated by wrapping an absorbable mesh around the right liver lobe and subsequently ligating the right portal vein branch extrahepaticaly. CONCLUSION: Mesh wrapping of the fragmented liver with absorbable mesh constitutes a safe and effective method, in treating grade IV and V liver injuries, especially when combined with ipsilateral ligation of the bleeding vessel.
RESUMEN
Introduction. In patients with extra-adrenal malignancy, an adrenal mass necessitates investigating the possibility of metastatic tumor. Curable adrenal metastasis are considered as a rare event. Case report. A 52-year-old male suffering from lower esophageal adenocarcinoma with a solitary left adrenal metastasis is presented herein, who underwent concomitant transhiatal esophagectomy and left adrenalectomy. The patient remains disease-free 18 months later. Discussion. Adrenal metastases mostly occur in patients with lung, kidney, breast, and gastrointestinal carcinomas. Primary esophageal adenocarcinoma gives adrenal metastatic deposits according to autopsy series with an incidence of about 3%-12%. When no other evidence of metastatic disease in cancer patients exists, several authors advocate adrenalectomy with curative intent. Isolated cases of long-term survival after resection of solitary adrenal metastasis from esophageal adenocarcinoma, like in our case, have been reported only as case reports. Conclusion. This study concludes that surgical resection may result in survival benefit in selected patients with solitary adrenal metastasis from esophageal adenocarcinoma.
