1/76. Primary gastric T-cell lymphomas: report of two cases and a review of the literature.

    To understand more fully the clinicopathological features of primary gastric T-cell lymphomas (PGTL), we report two cases of PGTL and review the literature. The present cases were not associated with human T-cell leukemia virus type 1 (HTLV-1) and were at clinical stage IIE. In both cases, T-cell origin of the lymphoma cells was diagnosed immunohistochemically. The clinical courses of these two cases were different: one followed a very aggressive clinical course and the patient died 6 months after the diagnosis, whereas the other patient survived more than 2 years without adjuvant chemotherapy. Clinicopathological features of 23 patients with PGTL are summarized with regard to their differences from primary small intestinal T-cell lymphomas (PSITL) and by association with HTLV-1. The median age at onset of PGTL was 58 years. The gender ratio was male-dominant (M:F = 2.3:1). About two-thirds (10 of 17) of PGTL cases had evidence of HTLV-1 infection. The most common presenting symptom for PGTL was upper abdominal discomfort and/or pain (76%), whereas that in PSITL was weight loss (61%) and diarrhea (42%). Typical lesions for PGTL were large ulcerations at the corpus to antrum. Neoplastic cells had no typical morphological characteristics for PGTL including HTLV-1-associated cases. CD3 4 8- was the most frequently observed surface phenotype of PGTL cells. Laboratory findings at diagnosis were not informative. Most patients were treated by gastrectomy with or without chemotherapy. PGTL, excluding that with HTLV-1, showed better prognosis than PSITL, although PGTL with HTLV-1 had a poorer prognosis.

2/76. Primary non-Hodgkin's lymphoma of the liver.

    The clinicopathological features of a rare case of primary non-Hodgkin's hepatic lymphoma (PHL) are described and compared to those of the other 76 cases reported in the world literature. PHL is mainly a disease of Caucasian, middle-aged males and, in approximately half of the reported cases, was associated with other diseases involving depression or chronic stimulation of the immune system. Right upper abdominal and epigastric pain with loss of weight are the most common presenting symptoms. The tumour is usually a single large mass involving both hepatic lobes and is almost invariably composed of lymphocytes reacting with B-cell markers. Most tumours are of intermediate or high grade according to the classification of the Working Formulation for Clinical Usage. No correlation is apparent between gross appearance of PHL (massive or nodular) and grade of severity. Chemotherapy or radiotherapy alone appears to be ineffective, while relatively good results can be obtained with combination modalities.

3/76. Malabsorption with progressive weight loss and multiple intestinal ulcers in a patient with T-cell lymphoma.

    We describe a 52-year-old woman who presented with severe diarrhea, nausea, intermittent abdominal pain and weight loss of 18 kg within ten months. Jejunal and duodenal ulcers were detected by endoscopy and multiple biopsies revealed villous atrophy of the jejunum. However, neither gliadin nor endomysium antibodies were detected and no clinical and histological improvement was achieved after gluten withdrawal. Despite strong clinical suspicion for intestinal lymphoma many unrevealing biopsies were done. The patient developed intermittent septic fever and diagnostic laparotomy revealed jejunal perforation. Partial jejunal resection was performed and histology confirmed the diagnosis of an intestinal T-cell lymphoma without celiac disease. Malabsorption and all intestinal ulcers disappeared during the course of chemotherapy (six cycles CHOP) and the patient recovered remarkably.

4/76. Intestinal capillariasis acquired in egypt.

    A 34-year-old Egyptian man presented with a 4-month history of profound weight loss, diarrhoea and abdominal pain. Extensive investigations in egypt had failed to provide a diagnosis but subsequent stool examinations revealed ova of capillaria philippinensis. The patient made a slow but complete recovery after treatment with albendazole. The literature on intestinal capillariasis is reviewed.

5/76. Diabetic neuropathic cachexia: the importance of positive recognition and early nutritional support.

    We report on a patient with acute painful diabetic neuropathy in whom abdominal pain and severe weight loss mimicked neoplastic disease. Positive recognition of the diabetic neuropathic cachexia syndrome might have avoided extensive invasive investigation. Intensive enteral nutritional support was associated with prompt resolution.

6/76. Pitfall: a pseudo tumor within the left liver lobe presenting with abdominal pain, jaundice and severe weight loss.

    A 51 year old male patient with a history of chronic alcohol consumption and recurrent pancreatitis was referred to our hospital with jaundice, epigastric pain, severe diarrhoea and weight loss of 28 kg within the last 12 months. A CT scan of the abdomen 4 months before admission had shown a pancreatitis with free fluid around the corpus and tail of the pancreas as well as dilated intrahepatic bile ducts and a cavernous transformation of the portal vein. Moreover, a tumor (3.5 x 3.0 x 3.6 cm) with irregular contrast enhancement was seen within the left liver lobe. The patient was referred to us for further evaluation and treatment. The initial B-Mode sonogram revealed a bull's eye like well defined lesion (8.1 x 7.5 x 7.0 cm) within the left liver lobe, consistent with a tumour or abscess. Prior to a diagnostic needle biopsy a PTCD was performed in this case presenting with dilated intrahepatic bile ducts and having a history of Billroth II operation. An additional colour coded Duplex Doppler ultrasonography demonstrated a visceral artery aneurysm and prevented us from performing the diagnostic puncture. The aneurysm was assumed to originate from a variant or a branch of the left hepatic artery. angiography revealed a pseudoaneurysm of the pancreaticoduodenal artery and coil embolization was performed because of the increasing size and the risk of a bleeding complication. Postinterventional colour duplex ultrasound measurement showed no blood flow within the aneurysm. Retrospectively, the pseudoaneurysm must have led to a compression of the common bile duct, since the patient did not develop cholestasis after embolization and removal of the PTCD. Thus, a pseudoaneurysm of the pancreaticoduodenal artery must be included in the differential diagnosis of liver tumours in patients with chronic pancreatitis, despite its unusual localization near the liver. Therefore, we suggest that colour coded ultrasonography should be applied to any unclear, bull's eye like lesion, even though this method alone cannot exactly determine the origin of the pseudoaneurysm. Interventional angiography remains the gold standard for the diagnosis and therapy of visceral artery aneurysm.

7/76. Primarily chronic and cerebrovascular course of lyme neuroborreliosis: case reports and literature review.

    As part of an ongoing study aiming to define the clinical spectrum of neuroborreliosis in childhood, we have identified four patients with unusual clinical manifestations. Two patients suffered from a primarily chronic form of neuroborreliosis and displayed only non-specific symptoms. An 11 year old boy presented with long standing symptoms of severe weight loss and chronic headache, while the other patient had pre-existing mental and motor retardation and developed seizures and failure to thrive. Two further children who presented with acute hemiparesis as a result of cerebral ischaemic infarction had a cerebrovascular course of neuroborreliosis. One was a 15 year old girl; the other, a 5 year old boy, is to our knowledge the youngest patient described with this course of illness. Following adequate antibiotic treatment, all patients showed substantial improvement of their respective symptoms. Laboratory and magnetic resonance imaging findings as well as clinical course are discussed and the relevant literature is reviewed.

8/76. Multifocal epithelioid angiosarcoma of the small intestine.

    A 67-year-old man presented with weight loss, intermittent severe abdominal pain and melaena. Initial radiology (including abdominal ultrasonography), gastroscopy and colonoscopy did not demonstrate any lesions that could explain the complaints. Three weeks later, upper gastrointestinal and small-bowel barium studies revealed two areas in the small intestine with an abnormal mucosal pattern. Explorative laparotomy revealed three tumoral lesions. Three partial enterectomies were performed. Gross examination showed centrally depressed dark reddish tumoral lesions extending from the mucosa throughout the full thickness of the bowel wall (diameter varying between 1.6 cm and 2.2 cm). The tumours, composed of large, plump, polygonal cells showing little architectural differentiation, were mainly situated in submucosa and muscularis propria. The growth pattern appeared rather solid. The epithelioid cells showed pronounced nuclear pleomorphism and atypia with central large nucleoli. There were several small blood vessels with occasional anaplastic endothelial cells. Immunohistochemical staining demonstrated an intense expression of CD 31, CD 34, factor viii related antigen and keratin. This supported the diagnosis of an epithelioid angiosarcoma. The patient died 3 months after diagnosis. Tumours of the small intestine are very rare, and angiosarcomas of the small intestine are even more rare. Epithelioid variants have only been described in two patients and only one of these had a multifocal presentation. The prognosis is very poor. Because of the epithelioid growth pattern and the cytokeratin expression, these tumours may erroneously be diagnosed as a carcinoma.

9/76. The primitive neuroectodermal tumor of the heart.

    A young man was admitted to hospital with dyspnea, malaise, chest pain and night sweating. Investigative studies revealed a cystic mass lesion originating from the heart. Surgical exploration of the tumor showed that it was unresectable and pathology of the biopsy material was primitive neuroectodermal tumor. Medical literature concerning this unusual type of tumor is reviewed.

10/76. Wegener's granulomatosis triggered by infection?

    Wegener's granulomatosis is a systemic disease of unknown origin, although recent studies suggest that auto-immune mechanisms and infection play a role in the pathogenesis of this disease. Wegener is characterized by a necrotizing vasculitis involving the lungs (pulmonary infiltrates), the upper airways and the kidneys (rapidly progressive glomerulonephritis). We present a case of a male patient admitted because of progressive deterioration of the general condition with weight loss, a unilateral neck mass, unilateral purulent rhinorrea and fever. CT-scan evaluation demonstrated a unilateral expanding mass in the sing-nasal cavity, obliterating the ethmoid complex. MRI revealed signs of intracranial inflammatory reaction and onset of absedation. A malignancy was suspected but a diagnosis of Wegener's granulomatosis was established based on histologic criteria (nasal biopsy) and a positive titer for anti-cytoplasmic antibodies (cANCA). During follow-up, nasal carriage of Staphyloccocus Aureus could be documented. An overview of Wegener's granulomatosis will be provided with emphasis on the potential role of acute infections as a trigger for Wegener's granulomatosis and the head and neck manifestations.
