[Nodular liver lesions with fever in a Moroccan man: hepatic brucelloma]

Hepatic brucelloma is an exceptional localization in brucellosis. The purpose of this report is to describe an uncommon case involving a 42-year-old man hospitalized for febrile hepatic cytolysis. Diagnosis was established based on positive rose bengal test results, positive blood culture, hypoechogenic masses on ultrasound, and hypodense enhancing masses on CT scan. Hepatic brucelloma is a focal suppurative lesion occurring after undetected acute brucellosis or undertreated brucellosis. Diagnosis is based on the association of imaging showing characteristic features (hepatic calcifications) and on positive blood culture and serology. First-line treatment should consist of doxycyclin and rifampicin for 2 to 12 months. If medical treatment fails, surgical drainage should be performed.

[Celiac crisis with quadriplegia due to potassium depletion as presenting feature of celiac disease]

INTRODUCTION

Adult coeliac disease revealed by coeliac crisis and quadriplegia due to potassium depletion is an extremely rare situation.

CASE REPORT

A 26-year-old woman presented with a suddenly developed weakness of all four limbs and a severe diarrhea. Authors emphasize coeliac crisis, which is a presenting feature of coeliac disease, characterized by acute diarrhea with life-threatening acid base and electrolyte abnormalities. The patient improved with correction of hypokalemia and gluten-free diet.

CONCLUSION

A severe acute diarrhea with metabolic and systemic complications, the so-called coeliac crisis, is a possible presenting clinical feature of a previously undiagnosed adult celiac disease.

[Primary gastric lymphoma: a retrospective series of 35 cases]

BACKGROUND

Primary gastric non Hodgkin's lymphoma (PGNHL) is the most common site of extranodal malignant lymphoma. It is a rare subtype of malignancy, for which no consensus exists about treatment.

AIM

The purpose of This paper was to assess the managemnt of PGNHL.

METHODS

Between January 1992 and December 2001, 35 patients were retrospectively evaluated.

RESULTS

Of the 35 patients, with a mean age of 44 years old Signs and symptoms are unspecific. 20 (57.1%) were in stage IE/IIE1. 15 patients (42.8%) were in stage IIE2,IIIE,IVE. These patients were treated with primary surgery with or without chemotherapy (11; 31.4%); primary chemotherapy (CT) alone with surgery in one patient (21; 60%) and three patients with gastric MALT lymphoma were treated by Helicobacter pylori eradication. The 5 year survival rates of the 35 patients are 62, 86%. There was no significant difference in the 5 year survival rate between the patients with low grade lymphoma and the patients with large grade lymphoma (75% versus 60%, P = 0.467). The 5-year survival rates for stage I/IIE1 and IIE2/III/IV patients were 80%, 53.3% respectively (p < 0.144). Of the 11 primary surgical groups with or without chemotherapy, the 5 year survival rate is 90.9%. Of the 21 patients who received CT, alone or combined with surgery, the survival rate is 52.4%. There was significant difference between the two groups (P = 0.05). Of the 3 patients with low-grade mucosa-associated lymphoid tissue (MALT) lymphoma with only oral anti-Helicobacter pylori regimen remained disease-free after a median follow-up of two years.

CONCLUSIONS

This study suggested that primary surgical resection may be important factor predicting the long-term survival of patients with primary gastric NHL. H. pylori eradication therapy was an effective first-line treatment for patients with gastric MALT lymphoma.

[Hodgkin's disease presenting with spinal cord compression]

INTRODUCTION

Hematological neoplasms may be complicated by signs of neurological compression. Most cases reported in the literature have described advanced-stage non-Hodgkin lymphomas. We report a case of spinal cord compression revealing an isolated vertebral localization of Hodgkin lymphoma.

CASE REPORT

Magnetic resonance imaging of the thoracic spine in a 54-year-old man who presented with spastic paraplegia revealed a vertebral and extradural mass. After laminectomy, histology and immunohistochemistry showed Hodgkin's disease. Post-operative staging did not reveal any other localization. The patient responded favorably after decompressive surgery and ABVD regimen.

CONCLUSION

Spinal cord compression is a rare complication of Hodgkin's disease, occurring in only 5p.cent of cases, usually in the setting of progressive, advanced disease. As the initial symptom of Hodgkin's disease, it is extremely rare, with only a few cases reported in the literature. Significant results may be obtained with decompressive surgery and chemotherapy when the disease is promptly diagnosed. Spinal cord compression by primary Hodgkin's disease is a very infrequent situation. We urge this diagnosis be considered in all patients presenting with spinal cord compression attributed to malignancy.

Hyperplasie angiolymphoïde à éosinophiles

INTRODUCTION

Angiolymphoid hyperplasia with eosinophilia is a rare affection.

CASE REPORT

A 36 years-old woman presented an angiolymphoid hyperplasia with eosinophilia manifesting by erythematous nodular lesions on the face and the forearms, severe neuropathy, visual loss and eosinophilia. Corticosteroids, immunosuppressive drugs and interferon-alpha were unsuccessful.

DISCUSSION

Angiolymphoid hyperplasia with eosinophilia is a dermatological disease with possible systemic features. Differential diagnosis with Kimura disease is based on clinical presentation and histological findings. Etiopathology remains unknown and the treatment is not codified.

[Isolated pseudo-tumoral tuberculosis of the spleen. A case report]

INTRODUCTION

The tuberculosis isolated tumoral spleen is rare, even in the countries to strong tubercular endemic.

EXEGESIS

From an observation, concerning an important, tumoral and isolated splenomegaly in 48-year-old-man. The authors put the accent on his tumorous variety by the clinic, the imagery and on macroscopic appearance of the operative piece. Are discussed the isolated character, the way of dissemination, the site of initial infestation and the deceitful character of haematological manifestations. A splenectomy to diagnostic and therapeutic goal have been realised, associated to the chemotherapy.

CONCLUSION

This is an expression of the profound organ's tuberculosis rich on endothelial reticular system. It's mean a singular topography of the bacillary lesion and a great distribution of the tubercular affect.

[Non-Hodgkin's lymphoma and hepatitis C virus infection]

INTRODUCTION

The authors report four cases of non Hodgkin's lymphomas (NHL) among patients infected by the hepatitis C virus (HCV). They discuss the epidemiological, physiopathological and clinical features of this association.

CURRENT KNOWLEDGE AND KEY POINTS

The role of the HCV in the development of B-cell NHL is probable but the reported frequency of the association with HCV infection is variable especially in different countries. Most of the reported cases are low-grade NHL with frequent extranodal involvement.

FUTURE PROSPECTS AND PROJECTS

New studies will improve the understanding of the physiopathological mechanisms that might explain the occurrence of NHL in the course of HCV infection. The recent evidence that the antiviral treatment is effective in splenic lymphoma with villous lymphocytes leads to reconsider the relationship between HCV and NHL and to think about new therapeutic possibilities.

[Digestive malacoplakia]

INTRODUCTION

Malacoplakia, a chronic granulomatous disease, rarely involves the digestive tube and, when it does, takes on a pseudotumoral aspect.

OBSERVATION

A 37 year-old man was hospitalized for chronic diarrhea that had progressed over 15 years. He exhibited an edematous-ascitic syndrome and bilateral pleurisy together with, biologically, a malabsorption syndrome. The endoscopic examinations (fibroscopy and colonoscopy) revealed polypoid tumor-like formations. An image of tumoral stenosis of the sigmoid-colic junction was revealed on barite lavage. Histological examination of the surgical sample (wide left colectomy of one third of the transverse) was suggestive of malacoplakia (histiocytes with characteristic Michaelis-Gutmann bodies).

DISCUSSION

Malacoplakia is an inflammatory disease predominantly affecting the urogenital tract. Other organs can be involved. Its clinical symptomatology is highly disparate. The interest of this disease is in its pathogenesis, on which, in fact, its treatment is based.

[What is new in antithrombotic treatment?]

Real progresses have been made during the past years in the comprehension of hemostasis mechanisms, along with rising of new antithrombotic drugs. The later include: 1) direct inhibitors of thrombin such as hirudin, bivalirudin, argatroban, melagatran and ximelagatran; 2) inhibitors of factor Xa such as the synthetic pentasaccharid and DX-9065a; 3) inhibitors of factor IXa; 4) inhibitors of tissue factor-factor VIIa complex such as tissue factor pathway inhibitor (TFPI) or NAPc2 (nematode anticoagulant peptide); 5) drugs enhancing endogenous anticoagulant activity, such as protein C or activated protein C; 6) drugs modulating endogenous fibrinolytic activity. These new drugs are promising a real decrease in mortality and morbidity due to venous thrombo-embolic disease, which is considered as a public health issue. Both physicians and biologists are concerned by these new antithrombotic agents, the former to think about new treatment strategies, the later to monitore, if necessary, the effects of such new drugs. Our review does not include antiplatelet agents which are indicated only in arterial thrombosis.

[Hyperthyroidism and atrioventricular block. Pathogenic hypothesis. Apropos of a case and review of the literature]

The authors report the case of a 26-year old male patient who had Graves' disease with a first degree atrioventricular block (AVB) and intermittent episodes of a second degree AVB of the Lucciani-Wenckebach type. These disorders of conduction had features characteristic of a nodal block and disappeared after treatment of the hyperthyroidism. The pathogenesis of atrioventricular conduction disorders in hyperthyroidism remains controverted. The authors put forward the following hypothesis: under the influence of thyroid hormones in excessive amounts, the autonomic nervous system would act by reciprocal excitation and exacerbate a patent or latent hypervagotonia which was pre-existent to the hyperthyroidism. This hypothesis needs to be tested by intracardiac electrophysiological studies with atrial stimulation.

[Sternocostoclavicular hyperostosis (Köhler's disease). A new case]

The authors report a new observation of Köhler's disease. Since Köhler's description in 1975, 40 observations have been noted. It concerns a particular entity characterized by a hyperostosis usually bilateral sternocosto clavicular able to associate other osseous lesions and cutaneous eruptions. Its etiology remains unknown.
