Takayasu's arteritis (TA) is a chronic large vessel vasculitis. The physiopathology of TA has not been completely elucidated, but it appears to be multifactorial and to mainly involve cellular immunity. The pathologic sequence could implicate stimulation from an antigen that triggers heat shock protein (HSP)-65 expression in aortic tissue which, in turn,(More)
BACKGROUND Subcutaneous fat necrosis (SFN) of the newborn is a rare acute transient hypodermatitis that develops within the first weeks of life in term infants. It often follows a difficult delivery. Prognosis is generally good except for the development of hypercalcaemia in severe cases. Only several case reports or small patients series have been(More)
To date, only a few series have analyzed the long-term outcome of giant cell arteritis (GCA) patients with aortic involvement, which prompted us to conduct the current retrospective study. Our aims were to 1) determine the prevalence of GCA in patients exhibiting nonatherosclerotic aortic involvement (that is, aortitis, aortic ectasia, and/or aneurysm); and(More)
INTRODUCTION Primary retroperitoneal synovial sarcoma is a rare malignant neoplasm that typically arises in young adults. We report here an unusual presentation of this tumor during hemorrhagic shock and retroperitoneal hematoma. CASE A 31-year-old man was admitted complaining of acute violent pain of the right lower abdominal quadrant. Physical(More)
INTRODUCTION We report a new case of pneumonia and bacteremia due to Yersinia enterocolitica (YE) in a diabetic patient with HLA-B27 positive spondylarthritis. OBSERVATION A 75-year-old man was admitted for a pneumonia. He was suffering from HLA-B27 positive spondylarthritis and stable diabetes mellitus. Amoxicillin with clavulanic acid was ineffective.(More)
We describe three patients with severe refractory cutaneous polyarteritis nodosa, resulting in painful ulcers involving the lower limbs and causing toe necrosis. Due to the severity of the cutaneous manifestations, the three patients received intravenous immunoglobulins at a dose of 1 g/kg/day for 2 days monthly. After the second intravenous immunoglobulin(More)
Skeletal muscle involvement is uncommon in lymphoma, occurring in less than 1.5% of patients. We report the original case of a 61-year-old man who presented with pseudotumoral muscle lesions of the lower limbs, revealing non-Hodgkin T-cell lymphoma. In our patient, magnetic resonance imaging (MRI) was useful in clearly revealing the detailed anatomic extent(More)
INTRODUCTION Erdheim-Chester disease is a rare non-Langerhans form of histiocytosis. We report the use of combined fluorodeoxyglucose positron emission tomography and computed tomography (18F-FDG PET-CT) in this disease. EXEGESIS Three men, aged from 55 to 74 years with confirmed Erdheim-Chester disease were included. 18F-FDG PET-CT allowed to detect(More)
Diagnosis of major hypereosinophilia (>1500 x 10(9)/L) is complex because the possible causes cover the entire range of medical specialties. History and clinical condition will usually suggest parasitic or allergic diseases or drug reactions. When workups for them are negative, rarer causes must be suspected: specific organ diseases (chronic eosinophilic(More)
PURPOSE The reported prevalence of cardiac complications is variable in patients with Churg-Strauss syndrome (15-92%) and depends on diagnostic tools. Diagnosis at early stage of heart involvement is crucial, resulting in appropriate management. METHODS We report three patients who developed cardiac manifestations, revealing Churg-Strauss syndrome. The(More)
