All necrotizing nodes are not tuberculosis – A report of two cases

IntroductionKikuchi-Fujimoto disease is a benign and self-limiting systemic disorder of unknown aetiology characterised by fever, superficial lymphadenopathy and leukopenia. In highly endemic & low-resource country like India, it is frequently misdiagnosed as tuberculosis.Case reportBoth the cases were diagnosed as necrotizing lymphadenitis by fine-needle aspiration cytology. Tuberculin skin prick test (TST) was positive for one case and negative for the other case. Cartridge based nucleic acid amplification test (CBNAAT) from lymph node aspirate was negative for mycobacterium tuberculosis in both the cases, later on histopathology of lymph node showed diagnosis of Kikuchi-Fujimoto disease.ConclusionKikuchi Fujimoto is a self-limiting disease systemic disease of unknown aetiology. A definite diagnosis can be established by incisional/excisional biopsy of the lymph node. When dealing with cases of tubercular lymphadenitis, Kikuchi-Fujimoto disease should be kept as differential diagnosis.     

Primary gastric melanoma： A case report

Melanoma accounts for 1-3 per cent of all malignant tumors. Except cutaneous, other less common melanomas include, among others, those in the GI tract. However, their primary or secondary nature is often difficult to establish. Referring to the stomach, scattered cases of primary melanomas have been reported in the literature. We report a case of a man with an ulcerated sub-mucosal mass at the antrum of the stomach, manifested with dull upper abdominal pain, nausea, vomiting, fatigue and anemia. This lesion was histologically proved to be melanoma. A detailed clinical and laboratory investigation revealed no primary site elsewhere. To our knowledge, very few cases of primary gastric melanoma have been reported. Our case is the fourth ever published and the first located at the antrum of the stomach. The debate upon the primitive nature of such lesions still persists. Thus, specific diagnostic criteria have been proposed.     

Primary gastric lymphoma

AIM:The purpose of this review is to describe the variousaspects of primary gastric lymphoma and the treatmentoptions currently available.METHODS:After a systematic search of Pubmed,Medscapeand MDconsult,we reviewed and retrieved literature regardinggastric lymphoma.RESULTS:Primary gastric lymphoma is rare however,theincidence of this malignancy is increasing.Chronic gastritissecondary to Helicobacter pylori (H pylori) infection has beenconsidered a major predisposing factor for MALT lymphoma.Immune histochemical marker studies and molecular biologyutilizing polymerase chain reaction have facilitated appropriatediagnosis and abolished the need for diagnostic surgicalresection.Advances in imaging techniques including MagneticResonance Imaging (MRI) and Endoscopic Ultrasonography(EUS) have helped evaluation of tumor extension and invasion.The clinical course and prognosis of this disease is dependenton histopathological sub-type and stage at the time ofdiagnosis.Controversy remains regarding the best treatmentfor early stages of this disease.Chemotherapy,surgery andcombination have been studied and shared almost comparableresults with survival rate of 70-90%.However,chemotherapypossesses the advantage of preserving gastric anatomy.Radiotherapy alone has been tried and showed good results.Stage IIIE,IVE disease treatment is solely by chemotherapyand surgical resection has been a remote consideration.CONCLUSION:We conclude that methods of diagnosis andstaging of the primary gastric lymphoma have dramaticallyimproved.The modalities of treatment are many and probablychemotherapy is superior because of high success rate,preservation of stomach and tolerable complications.     

Primary non-Hodgkin’s lymphoma presenting as radicular syndrome: report of two cases

We report two cases of primary Non-Hodgkin’s Lymphoma in the spine leading to radicular compression secondary to infiltration of lumbar body vertebras. The two patients were free of either nodular or other extra-nodular disease. Treatment consisted of chemotherapy alone, one patient have had a cauda equina syndrome and surgical decompression was performed in emergency. The patients were in remission for 20 months after diagnosis. A review is given for the incidence of primary vertebral localization of lymphoma, its diagnosis, treatment and prognosis.     

Abdominal cocoon – A rare case of intestinal obstruction: A report of two cases

We present the imaging findings in 2 adolescent girls with abdominal cocoon formation, a rare cause of intestinal obstruction. It may be primary/idiopathic or secondary in nature and is characterized by small bowel encapsulation. Familiarity with the imaging findings and a high index of suspicion helps in reaching the diagnosis pre-operatively in this rare condition and hence planning surgical management.     

Primary pancreatic lymphoma： Report of six cases

AIM: To heighten recognition of primary pancreatic lym phoma (PPL) in clinical practice. METHODS: A retrospective review of the clinical presentation, imaging characteristics and pathological features of PPL patients were presented, as well as their diagnosis and treatment, in combination with literature review. RESULTS: Histological diagnosis was made in four patients by surgery and in two patients by EUS-FNA. The six PPL patients (5 males and 1 female; age range, 16-65 years; mean age, 46 years) had the duration of symptoms for two weeks to three months. The primary presenting symptoms, though not characteristic, were abdominal pain, abdominal masses, weight loss, jaundice, nausea and vomiting. One of the patients developed acute pancreatitis. In one patient, the level of serum CA19-9 was 76.3μg/L. Abdominal CT scan showed that three of the six tumors were located in the head of pancreas, two in the body and tail, and one throughout the pancreas. Diameter of the tumors in the pancreas in four cases was more than 6 cm, with homogeneous density and unclear borders. Enhanced CT scan showed that only the tumor edges were slightly enhanced. The pancreatic duct was irregularly narrowed in two cases whose tumors were located in the pancreatic head and body, in which endoscopic retrograde cholangiopancreatography (ERCP) showed that the proximal segment was slightly dilated. Two patients underwent Whipple operation, one patient underwent pancreatectomy, and another patient underwent operative biliary decompression. PPL was in stage I E in 2 patients and in stage II E in 4 patients according to the Ann Arbor classification system. The diagnosis of B-cell non-Hodgkin's lymphoma was made in all patients histopathologically. All six patients underwent systemic chemotherapy, one of whom was also treated with gamma radiometry. One patient died two weeks after diagnosis, two patients lost follow-up, two patients who received chemotherapy survived 49 and 37 mo, and the remaining patient is still alive 21 mo, after diagnosis and treatment. CONCLUSION: PPL is a rare form of extranodal lympho-ma originating from the pancreatic parenchyma. Clinical and imaging findings are otherwise not specific in the differentiation of pancreatic lymphoma and pancreatic cancer, which deserves attention. EUS-guided fine-needle aspiration (EUS-FNA) of the pancreas requires experienced cytopathologists as well as advanced immunohis-tochemical assays to obtain a final diagnosis on a small amount of tissue. Surgery and adjuvant chemotherapy or radiotherapy can produce fairly good outcomes.     

Primary liposarcoma of esophagus： A case report

Liposarcoma is the most common soft tissue sarcoma inadult life while esophageal liposarcoma is an extremelyrare tumor.In the world literature,only 14 cases ofesophageal liposarcomas have been described.We reporta 72-year old male patient who was urgently admittedto our hospital for acute epigastric pain with a burningretrosternal sensation,persistent nausea,vomiting anddysphagia.Barium swallow,upper gastrointestinal(GI)endoscopy,esophageal manometry and CT scan,failedto accurately diagnose the lesion.After surgical resectionof an esophageal polypoid tumor,the histologicalexamination revealed a well-differentiated grade Iliposarcoma.Diagnostic and therapeutic tools were dis-cussed and the results of literature were reviewed.

The fight against gastric cancer – the IARC Working Group report

Gastric cancer is the third cause of cancer death worldwide, and Helicobacter pylori infection causes almost 90% of non-cardia cancers, the predominant type. H. pylori infection is treatable, and in clinical trials there is evidence of a 30–40% reduction in incidence of gastric cancer among treated subjects. However, with a few exceptions, there are no public health programmes for gastric cancer prevention. In December 2013, the International Agency for Research on Cancer (IARC), organized a Working Group of international experts to discuss and make recommendations for gastric cancer control. The Working Group considered that the enormous burden of disease, which is not expected to decline in the coming decades, requires decisive public health action to include gastric cancer in cancer control programmes. Interventions should be tailored to the local conditions and consider population-based screening and eradication of H. pylori, in the context of evaluation of feasibility, efficacy and adverse consequences.     

Primary jejunoileal neoplasmas： a review of 60 cases

AIM: Primary neoplasmas of the jejunum and ileum are infrequent and lack specific manifestations and inaccessibility of conventional endoscopy, so the diagnosis of these tumors are usually delayed. So far the data of primary jejunoileal neoplasmas is still scarce, especially in Chinese medical literature in English. There may be some differences among the Chinese and the westerners in jejunoileal neoplasmas. METHODS: A retrospective analysis was made on clinical findings and pathological types. RESULTS: Of the 60 patients with jejunal or ileal neoplasmas, the most frequent symptom was abdominal pain (57 %), followed by tarry stool (43 %) and hematochezia (10 %). Abdominal mass (40 %) was the most common finding on physical examination, followed by anemia and weight loss (35 %). 67 % of the jejunoileal neoplasms were located in the jejunum. Among the malignant neoplasmas (68 %), malignant stroma (47 %) was most common, while the benign stromoma (20 %) was the most common benign neoplasmas. Preoperatively, 40 patients (67 %) were diagnosed as small bowel neoplasmas, of which 34 were found by enteroclysis. Abdominal mass was shown by CT in 18 cases and by ultrasonography in 13. The mean duration of symptoms before diagnosis was 7 months. In 41 patients with malignant tumors, the duration of symptoms before diagnosis exceeded 12 months in 21 cases, lymphatic or distant metastases were found in 26 (63 %)cases during operation. An emergency laparotomy was performed in 4 patients (7 %) owing to intestinal obstruction or perforation. CONCLUSION: Primary jejunoileal neoplasmas in Chinese present some difference from Westerners on clinical features and histopathologic types. Enteroclysis remains the major relevant diagnostic procedure in this study, the misdiagnotic rate is high preoperatively due to failure of detection by conventional imaging procedures such as CT and inaccessibility of routine endoscopy. For the suspected patients, combined application of aforementioned procedures may facilitate early diagnosis. The wireless capsule endoscopy may improve the diagnostic rate of jejunoileal neoplasmas in the future.     

Immune thrombocytopenic purpura associated with rheumatoid arthritis – a report of five cases and review of the literature

Immune thrombocytopenic purpura (ITP) associated with rheumatoid arthritis (RA) is relatively rare. We describe five cases of RA with ITP. In all five patients, platelet counts were low, platelet-associated IgG levels were elevated, and bone marrow aspiration showed megakaryocytosis. Glucocorticoid therapy was effective in three cases, but the other two cases required immunosuppressants or intravenous γ-globulin in addition to glucocorticoid. We review the reported cases of RA with ITP and discuss the pathophysiology and differential diagnosis of thrombocytopenia in RA. Received: September 25, 2000 / Accepted: February 16, 2001     

Immune thrombocytopenic purpura associated with rheumatoid arthritis – a report of five cases and review of the literature

Abstract

Immune thrombocytopenic purpura (ITP) associated with rheumatoid arthritis (RA) is relatively rare. We describe five cases of RA with ITP. In all five patients, platelet counts were low, platelet-associated IgG levels were elevated, and bone marrow aspiration showed megakaryocytosis. Glucocorticoid therapy was effective in three cases, but the other two cases required immunosuppressants or intravenous γ-globulin in addition to glucocorticoid. We review the reported cases of RA with ITP and discuss the pathophysiology and differential diagnosis of thrombocytopenia in RA.     

Small bowel anisakiosis： A report of two cases

Small bowel stenosis is a serious complication of intestinal anisakiosis. The aim of this report is to investigate whether severe stenosis of the small intestine can be conservatively managed. We treated two patients with severe stenosis of the small intestine caused by anisakiosis. Surgical intervention was eventually performed on the 23rd and 35th in the hospital, respectively. Histopathological examination of the resected specimens revealed that the intestinal wall had been completely damaged by the inflammatory reaction of anisakiosis, and that the damage was irreversible, thereby suggesting that laparotomy is needed in cases of severe small bowel stenosis caused by intestinal anisakiosis, even if a long period of conservative treatment for the intestinal anisakiosis allowed the patient to pass successfully through the acute phase.     

Non-parasitic splenic cysts： A report of three cases

Primary splenic cyst is a relatively rare disease, and the majority of cases are classified as epithelial cysts. Three cases with nonparasitic splenic cysts are presented: two epithelial and one pseudocyst. All cases had an atypical symptomatology, consisted mainly of fullness in the left upper abdomen and a palpable mass. Preoperative diagnosis was established with ultrasonography and computerized tomography. Two cases with large cysts located in the splenic hilum were treated with open complete splenectomy. The most recent case, a pseudocyst, was managed laparoscopically with partial cystectomy. All cases did not have any problems or recurrence during follow-up. Laparoscopic partial cystectomy is an acceptable procedure for the treatment of splenic cysts, because it cures the disease preserving the splenic tissue. Complete splenectomy is reserved for cases in which cyst excision cannot be done otherwise.     

Use of external defibrillator jacket to facilitate safe delivery of radiotherapy for lung cancer – A report of two cases

The increasing rate of implantable cardioverter defibrillator (ICD) implantation coupled with shared risk factors between lung cancer and ischemic cardiac disease means that the need for radiotherapy in cardiac device patients is set to become commonplace. We describe two cases referred to our electrophysiology service over a 6-month period. Both had been diagnosed with lung cancer in tissue directly posterior to a previously implanted ICD device. The cases highlight the risks to device function caused by ionizing radiation, the practical difficulties and ethical dilemmas of delivering radiotherapy to cardiac device patients safely and a novel setting for the use of a wearable defibrillator system.     

Conservative management of post-intubation tracheal tears—report of three cases

Iatrogenic tracheal rupture is a rare complication after intubation. We present three patients with tracheal tears. In all of these patients, a common finding was a lesion of the posterior tracheal wall with postoperative subcutaneous and emphysema as the first clinical sign of the rupture. Diagnosis and follow-up were based on clinical and endoscopic findings and chest computed tomography (CT) scans. In our cases with progressive subcutaneous and mediastinal emphysema or dyspnea, we performed a tracheotomy and bypassed the lesion with a tracheostomy tube to avoid an increase in air leakage into the mediastinum. Under broad-spectrum antibiotic therapy, no mediastinitis occurred and all patients survived without sequelae. Closure of tracheostomy was scheduled for 1-2 months after tracheal injury. Analysis of surgical and anesthesiological procedures revealed no abnormalities and the accumulation of tracheal injuries was considered as accidental. We found that in clinically stable patients with spontaneous breathing and with no mediastinitis, a conservative management of tracheal tears is a safe procedure.     

Liver retransplantation:report of 80 cases and review of literature

BACKGROUND: Because the orthotopic liver transplantation (OLT) was performed widely in recent 5 years throughout China, the proportion of recipients whose graft function deteriorated to be retransplantation candidates increased gradually. This study was undertaken to analyze clinical experience of orthotopic liver retransplantation (re-OLT) at our center. METHODS: The medical records of 80 patients who had undergone liver retransplantation at our center from January 1999 to July 2005 were analyzed retrospectively, including indications and timing of retransplantation, surgical techniques, and the causes of death. RESULTS: The commonest cause leading to hepatic graft loss and subsequent retransplantation was biliary complications in 36 patients (45%). The patients underwent retransplantation more than 30 days after their primary transplant recovered better than those who underwent retransplantation within 8-30 days after primary transplantation (peri-operative mortality 19.6% versus 70%). Sepsis (12 of 22 patients, 54.5%) and multiple organ failure (4 of 22 patients, 18.2%) were leading causes of re-OLT recipient deaths. CONCLUSIONS: Proper indications and optimal operative time, surgical procedures, perioperative monitoring and appropriate postoperative treatment contribute to the improvement of the survival rate of patients after liver retransplantation.     

Idiopathic sclerosing encapsulating peritonitis （or abdominal cocoon）： A report of 5 cases

Sclerosing encapsulating peritonitis （SEP） is a rare cause of intestinal obstruction that is characterized by a thick grayish-white fibrotic membrane encasing the small bowel. SEP can be classified as idiopathic, also known as abdominal cocoon, or secondary. It is difficult to make a definite pre-operative diagnosis. We experienced five cases of abdominal cocoon, and the case files were reviewed retrospectively for the clinical presentation, operative findings and outcome. All the patients presented with acute, subacute and chronic intestinal obstruction. Computed tomography （CT） showed characteristic findings of small bowel loops congregated to the center of the abdomen encased by a soft-tissue density mantle in four cases. Four cases had an uneventful post-operative period, one case received second adhesiolysis due to persistent ileus. The imaging techniques may facilitate pre-operative diagnosis. Surgery is important in the management of SEP.
