[Hypercalcemia related to PTH-rP revealing malignant hepatic epithelioid hemangioendothelioma]. / Une hypercalcémie humorale maligne révélant un hémangioendothéliome épithélioïde du foie.

Hypercalcemia caused by tumor production of PTH-rp occurs most often in cases of squamous cell carcinoma of the lung, aerodigestive tract cancer, gynecological cancer and lymphoma. We report an exceptional case of PTH-rp related to a hepatic hemangioendothelioma. A 70 years-old male admitted for deterioration of the general state. The laboratory investigations revealed hypercalcemia, related to tumor production of PTH-rp. Imaging revealed tumoral hepatic lesions. Histopathological study and immunohistochemistry showed diffuse response for CD31 marker, CK20 (+) with CK7 (-) and hepatocyt antigen (-). The diagnosis of PTH-rp related to hepatic hemangioendothelioma was make. The patient died with recurrence of fatal hypercalcemia. Management of patients presenting with humoral hypercalcemia includes a vigorous search for tumor lesions. Elevated PTH-rp can be a bad prognostic factor. In front of tumoral liver lesions, a hepatic epithelioid hemangioendothelioma must be considered. Immunohistochemistry is necessary to make diagnosis.

[Characteristics of deep vein thrombosis in the elderly]. / Particularités de la thrombose veineuse profonde chez le sujet âgé.

PURPOSE OF THE STUDY: Deep vein thrombosis is a common condition in geriatric. The identification of risk factors for venous thrombosis in the elderly is important because it allows an appropriate prescription of preventive treatments. The purpose of this study is to identify the etiologic and therapeutic characteristics of deep vein thrombosis of the lower limbs in the elderly. PATIENTS AND METHODS: A retrospective study of 155 patients with lower limb deep vein thrombosis confirmed by venous Doppler. These patients were divided into two groups: group 1 (patients aged 65 years or more) and group 2 (patients whose age was below 65 years). A comparison between these two groups was performed. RESULTS: The average age of patients in group 1 was 74.89 years (± 6.43). The sex ratio in this group was 0.68. The thrombosis was more frequently proximal in patients of group 1. Patients of group 1 had significantly more risk factors than those of group 2 (p <0.05). Among risk factors studied, only the cancers were significantly more frequent in group 1 (p = 0.002). The frequency of hemorrhagic events in both groups was comparable but bleeding was more common in patients of group 1 with cancer. CONCLUSION: Our study confirms the multifactorial origin of deep vein thrombosis in the elderly and the incidence of malignant etiology. The results of this study also call for vigilance in the use of anticoagulants in the elderly especially in the presence of cancer because it is an additional risk factor for bleeding.

[Syndrome d'activation macrophagique: une série de 11 cas tunisiens]. / Hemophagocytic syndrome: a study of 11 patients in tunisian population.

BACKGROUND: Hemophagocytic syndromes are mostly associated with underlying pathology, they can reveal: immunodeficiency, infections, hemopathies, cancers and auto-immune diseases. AIM: to investigate clinical, biological features, outcome characteristics and underlying pathology of Tunisian patients with hemophagocytic syndromes. METHODS: A retrospective study of patients with hemophagocytic syndromes admitted in an internal medicine department in Tunis over the period 2009-2012. RESULTS: There were 11 patients included, 4 men and and 7 women. Mean age was 47,3years. Purpura was observed in 3 cases, hepatosplenomegaly in 6 cases and peripheral lymph nodes in 3 cases. Hemorrhagic complication was noted in 2 cases. There were an increase of inflammatory indices in all the cases. Eight patients had pancytopenia and 3 had bicytopenia. Six patients developed intravascular dissiminated coagulation. High levels of triglyceridemia was noted in 5 cases and an hyperferritinaemia in all cases. Cytological examination of bone marrow confirmed hemophagocytosis in ten cases. Hemophagocytosis was associated to infectious diseases in 6 cases, there were 2 cases of leishmaniasis, septicemia to E.Coli and staphylococcus aureus and lymph nodes tuberculosis with HIV. We also noted a case of lymphoma, myelodysplasic syndrome, rheumatoid polyarthritis, adult onset still's disease. In one patient, the origin of hemophagocytosis remained indefinite. Visceral leishmaniose were treated by Glucantime®, adult Still's disease by corticosteroids and méthrotrexate®, lymphoma by chemotherapy. In lymph nodes tuberculosis, there were good evolution. Six patients died. CONCLUSION: Hemophagocytic syndrome is a rare and life-threatening disease. Pejorative prognosis requires an early therapy with etiological treatment.

[A leukemoid leucocytosis]. / Une hyperleucocytose « leucémoïde ¼

Leukemoid reaction is a rare paraneoplastic syndrome. It can occur in association with carcinomas, in particular of the lung, gastric and renal. However, its association with sarcoma is infrequent. Leukemoid reaction occuring in patients with uterine sarcoma have not been previously reported. We report the case of a « leukemoid ¼ leucocytosis revealing an uterine sarcoma with fatal evolution.

[Chronic disseminated intravascular coagulation caused by aortic dissection]. / Coagulation intravasculaire dissiminee revelant une dissection de l'aorte.

BACKGROUND: Disseminated intravascular coagulation (DIC) is a severe disease. It can be caused by loss of pathology. CASE REPORT: We report the case of chronic aortic dissection discovered during the evaluation of disseminated intravascular coagulation (DIC). This case is characterised by the severity of clinical presentation, challenging diagnosis and difficulty of therapeutic approach. Low dose of heparine may reduce the severity of this situation; but vital prognosis remains obscure. CONCLUSION: aortic dissection is a rare but a severe cause of disseminated intravascular coagulation

[Renal amyloidosis during Behçet's disease. Study of one case]. / Amylose compliquant une maladie de Behçet: a propos d'un nouveau cas.

BACKGROUND: Amyloidosis in Behçet's disease is rare and has a poor outcome. AIM: Report a new case. CASE: We report a case of a 38-year-old Tunisian woman who presented with Behçet's disease and nephrotic syndrome. Renal biopsy showed amyloid deposition consistent with AA type. She had not any associated disease that might be an additional cause of secondary amyloidosis. She was treated by colchicine. After 3 years, proteinuria had disappeared and persisted negative 11 years after the diagnosis. A second renal biopsy showed the persistence of amyloidosis. CONCLUSION: As amyloidosis is one of the prognostic factors affecting survival in Behçet's disease, patients with this disease should be screened for amyloidosis. Administration of colchicine to these patients may be beneficial.

[Cutaneous lupus profundus]. / Le lupus cutané profond.

The objective of this studies is to review clinical and laboratory features of lupus panniculitis. The authors report 3 cases of lupus profundus from a group of 70 lupus erythematosus. In both cases the lupus panniculitis presented as subcutaneous infiltrated and indurated nodules. The diagnosis was confirmed on clinical, histological and therapeutic data. The evolution is slow and is characterised by regression of the inflammatory lesions with treatment by antimalarial drugs. The lupus panniculitis has generally a favorable prognosis.
