Lymphoepithelioma-like gastric carcinoma presenting as giant ulcer of the lesser curvature: case report.

Lymphoepithelioma-like gastric carcinoma (LELGC) has special clinicopathologic features that differentiate it from the common gastric adenocarcinoma. LELGC is a rare neoplasm of the stomach with an incidence of 1-4% of all gastric cancers and is characterized by desmoplastic stroma uniformaly infiltrated by abundant lymphocytes and plasma cells. LELGC is closely associated with the Epstein-Barr virus (EBV), with 80-100% of LELGC being EBV-positive.

Spontaneous cholecystocutaneous fistula draining from an abdominal scar from previous surgical drainage.

We present a rare case of cholecystocutaneous fistula draining from an old surgical scar in the right upper abdominal quadrant following chronic calculous cholecystitis. A 71 year old male presented to the emergency department with a persistent bilious drainage from an old surgical scare, from surgical drainage, of the right upper abdominal quadrant for about a week. Cultures from the draining fluid grew Staphylococcus hominis, Escherichia coli and Klebsilla pneumoniae and tigecycline 50 mg twice a day was administrated intravenously to the patient according to sensitivity results.

Recurrent small intestine intussusception in a patient with Peutz-Jeghers syndrome.

Peutz-Jeghers syndrome is a rare hereditary autosomal dominant disease caused by a mutation of the tumor suppressor gene serine/threonine kinase 11 located in chromosome 19p13.3. It is characterized by the presence of extensive mucocutaneous pigmentation, especially of the lips and the occurrence of hamartomatous polyps throughout the gastrointestinal tract.

Long term follow up of eosinophilic granuloma of the rib.

Unlabelled: BACKROUNDS: Eosinophilic granuloma is one of the rarest causes of bone tumors, especially in adults. Eosinophilic granuloma is the commonest form of Langerhans cell histiocytosis and represents the unifocal osseous form of the disease which usually affects the skull and long bones. Eosinophilic granuloma, is a benign disease in which diagnosis and differential diagnosis presents more difficulties than treatment.

Acute adult intussusception caused by primary cecal non Hodgkin lymphoma.

Intussusception of the bowel is rather rare in adults and in about 80-90% of the cases is secondary to an underlying intraluminal pathology that serves as a lead point. In cases of colonic intussusception malignancy occurs in 63-66% of patients and it is usually adenocarcinoma and rarely lymphoma. The presenting symptoms are non specific and are in most cases of long duration, consistent with a chronic intussusception causing partial intestinal obstruction.

Emphysematous cellulitis of the left thigh caused by sigmoid diverticulum perforation.

Necrotizing fasciitis and gas gangrene of the lower extremities are two life-threating emergencies and are the most common causes of gas presence in the lower extremity. Rarely the gas presence is secondary to a perforated viscus and especially the colon. Large bowel diverticula are a quiet common disease in western countries and their prevalence increases with age.

Acute respiratory failure caused by neglected giant substernal nontoxic goiter.

Substernal goiter is usually defined as a goiter in which the thyroid mass has descended the plane of the thoracic inlet or if more than 50% of the thyroid mass is located below the thoracic inlet. Substernal goiters may be asymptomatic or may present with symptoms caused by compression of adjacent organs. Acute respiratory failure is rare in cases of substernal goiter.

Pathologic Rupture of the Spleen as the Presenting Symptom of Primary Splenic Non-Hodgkin Lymphoma.

Pathologic splenic rupture is defined as the spontaneous rupture of a diseased spleen and is quite rare. It is usually associated with oncologic, infectious, and hematologic diseases and more seldom with other rare causes. Pathologic splenic rupture related to hematologic malignancy seems to be rare with only 136 cases reported from 1861 until 1996 and a few cases thereafter.

Mesothelial mesenteric cyst in patient with ascending colon cancer. Case report.

Mesenteric cysts are rare cystic malformations of the mesentery. They are usually located at the iliac mesentery. Clinically most mesenteric cysts are asymptomatic, but sometimes they present with non-specific abdominal symptoms.

Streptococcus mutans: a rare cause of retroperitoneal abscess.

Retroperitoneal abscesses are uncommonly encountered clinical entities and they represent serious surgical infections associated with significant mortality rates because of their insidious clinical manifestations and diagnostic difficulty. The source of retroperitoneal infections is usually an organ contained within or abutting the retroperitoneum, usually the kidney and the microorganisms most commonly isolated are gram-negative bacilli. Gram-positive cocci, mainly staphylococcal species and rarely streptococcal species, are a less common cause of retroperitoneal abscess and are usually isolated in cases of hematogenous spread.

Ingested toothpick fistula of the ileum mimicking Crohn's disease.

Foreign body ingestion is an accidental or an intentional event, with most of the ingested foreign bodies passing spontaneously through the gastrointestinal tract without incidents. About 10-20% of them, especially long and sharp objects like toothpicks, will fail to pass through the entire gastrointestinal tract and may cause symptoms. Toothpick injury of the gastrointestinal tract is often associated with considerable morbidity and mortality.

Giant bilateral symptomatic adrenal myelolipomas associated with congenital adrenal hyperplasia.

Adrenal myelolipoma is an uncommon, benign, biochemically non-functioning and endocrinologically inactive tumor composed of variable amounts of mature adipose tissue and scattered islands of haemopoietic elements, including erythroid, myeloid and lymphoid series, as well as megakaryocytes. Diagnosis of myelolipomas is based on imaging, with ultrasonography, CT and MRI being effective in more than 90% of cases. Differential diagnosis includes other containing fat adrenal masses such as teratoma, lipoma and liposarcoma.

Sister Mary Joseph's nodule as the sole presenting sign of gastric signet ring cell adenocarcinoma.

The Sister Mary Joseph's nodule is a periumbilical metastatic tumor originating from advanced metastatic intra-abdominal and intrapelvic malignancies. It is an inconspicuous and uncommon clinical sign, which not only shows the presence of visceral malignancy but also reveals the poor prognosis of these malignancies. The majority of cases originate from gastrointestinal or ovarian cancer.

Splenic artery aneurysm in a cardiac transplant patient: a case report.

We present the case of a 61-year-old woman who underwent repair of a symptomatic 4-cm splenic artery aneurysm. This patient had received heart transplantation for hypertrophic congestive cardiomyopathy 5 years before this event. She was under immunosuppression therapy with cyclosporine, prednisone and azathioprine.

Endovascular repair of traumatic aortic transection.

The present study reports a single center experience and mid-term results of endovascular repair of acute aortic traumatic transection on an emergency basis, instead of open surgical management. From January 2005 to December 2008, 13 cases of traumatic aortic transection with serious comorbidities, which underwent repair with thoracic stent grafts at our institution, were reviewed. The mean patient age was 32.

Fibroepithelioma of pinkus in continuity with nodular basal cell carcinoma: supporting evidence of the malignant nature of the disease.

Basal cell carcinoma, the most common skin cancer, has several clinical and histopathological variants, with its most common form being nodular basal cell carcinoma. Fibroepithelioma of Pinkus is considered as an unusual variant of basal cell carcinoma by some authors while others consider it to be a benign analogue of basal cell carcinoma. We present a rare case of fibroepithelioma of Pinkus in continuity with a nodular basal cell carcinoma, a finding that supports the classification of fibroepithelioma of Pinkus as a variant of basal cell carcinoma.

Pilomatricoma of the arm with extensive ossification.

Pilomatricoma is a benign skin tumor derived from the hair follicle, usually located in the head and neck and presenting in the first two decades of life. Clinically it most commonly presents as a hard, mobile, well circumscribed nodule. Microscopically it is characterized by the presence of shadow cells and may show calcification, while extensive ossification is rare.

Giant cutaneous plasmacytoma of the sacrococcygeal region.

Background: Cutaneous plasmacytoma is a very rare manifestation of extramedullary plasmacytoma, with only 32 cases having been reported so far in the last 60 years. Extramedullary plasmacytoma is a plasma cell tumor that involves soft tissues, without any signs of systemic spread of multiple myeloma or bone marrow involvement. The cutaneous lesions usually range in diameter from 1 to 5 cm and can be treated with radiotherapy or surgical excision.

Profunda femoris as an access site vessel for a hybrid approach to the treatment of a para-anastomotic common iliac artery aneurysm and intermittent claudication, occurring after previous abdominal aortic thbe graft repair and femoro-femoral bypass graft. A case report.

A true para-anastomotic right common iliac artery aneurysm and intermittent claudication developed in a 76-year-old man 5 years after open abdominal aortic aneurysm repair with a Dacron tube graft. Following the initial operation the patient developed acute left iliac occlusive disease necessitating an immediate right-to-left femoro-femoral crossover bypass graft. The patient was a poor open surgical candidate because of multiple medical comorbidities.

Primary myeloid sarcoma of the jejunum and greater omentum causing small intestine obstruction.

Myeloid sarcoma, which is highly associated with acute myeloid leukemia, is defined as an extramedullary discrete tumor mass, consisted by immature myeloid cells or myeloblasts. Myeloid sarcoma usually involves the skin, lymph node, bone, soft tissue and testis, while involvement of the gastrointestinal tract is rather uncommon. The diagnosis depends on histological features and immunohistochemical results.

Early endograft collapse following endovascular treatment of a traumatic thoracic aortic disruption: a case report.

The authors present the case of a 39-year-old man who underwent endovascular repair of a thoracic aortic disruption. Implantation of a Gore TAG stent-graft achieved total exclusion of the traumatic lesion with no contrast extravasation. However, on the third postoperative day, the patient developed complete anuria necessitating continuous venovenous hemofiltration.

Sleep-disordered breathing and quality of life of railway drivers in Greece.

Background: Sleep-disordered breathing (SDB) and especially obstructive sleep apnea (OSA) are associated with daytime sleepiness and an increased risk for motor vehicle crashes. Previous studies have assessed the prevalence of OSA among professional drivers, but no study so far has focused on railway drivers. The aim of this study was to assess the prevalence of SDB among Greek railway drivers, and correlate it with daytime sleepiness, quality of life, and symptoms.

Reliability of selective surveillance colonoscopy in the early diagnosis of colonic ischemia after successful ruptured abdominal aortic aneurysm repair.

Purpose: To evaluate the reliability of selective surveillance colonoscopy based on 6 specific perioperative risk factors in the early diagnosis of colonic ischemia (CI) after successful ruptured abdominal aortic aneurysm (rAAA) repair.

Patients And Methods: From 1999 to 2005, 62 consecutive patients underwent rAAA repair. In 59 of them, routine aggressive surveillance colonoscopy was offered every 12 hours within the first 48 hours, and CI was graded consistently.

Does leukodepletion during elective cardiac surgery really influence the overall clinical outcome?

Aim: We examined the impact of leukocyte filtration during the entire bypass time on postoperative leukocytosis, perioperative hemorrhage and overall clinical outcome in patients undergoing elective cardiac surgery.

Methods: Eighty patients who electively underwent cardiac surgery were randomly allocated to a leukocyte depletion group (n=40) or a control group (n=40). In patients of the leukocyte depletion group an arterial line filter with leukocyte depleting capacity (Pall LG6) was applied instead of a standard arterial line filter.
