Nasal oral fistula revealing Langerhans´ cell histiocytosis in adult patient: case report.

Langerhans cell histiocytosis (LCH) is a rare systemic disease caused by proliferation of mature histiocytes; its association to histiocyto fibroma is rarely reported. It rarely affects adults. We report a case of systemic LCH, in an adult patient with osteolytic lesion causing a fistula between the left nasal cavity and hard palate, involving the bone, lung, lymph node and associated to multiple histiocyto fibroma.

Elderly-onset adult Still's disease.

Adult-onset Still's disease is a rare inflammatory disorder usually affecting young adults. Elderly-onset Still's disease (EOSD) is reported in some cases, commonly in Japan, the USA and Europe. One of the most commonly used criteria for diagnosing EOSD is Yamaguci criteria.

Systemic lupus erythematous revealed by cytomegalovirus infection.

Cytomegalovirus (CMV) infection have been described as exacerbing systemic lupus erythematous (SLE). The role of CMV in starting off SLE remains object of debate. We report a severe presentation of SLE revealed by CMV infection with hemophogocytic syndrome.

Amyloïdosis, sarcoidosis and systemic lupus erythematosus.

The occurrence of renal and multiple organ Amyloïdosis is currently considered exceptional in the course of systemic lupus erythematosus. We report a case of a concomitant SLE and Amyloïdosis in a 57 year old female patient with hypothyroidism history, who presented with erythema nodosum, fever, arthralgia and sicca syndrome. Biological findings showed an inflammatory syndrome, renal failure, proteinuria (1g / 24h), positive auto antibodies and anti DNA.

[Multifocal tuberculosis in immunocompetent patients].

Multifocal tuberculosis is defined as the presence of lesions affecting at least two extrapulmonary sites, with or without pulmonary involvement. This retrospective study of 10 cases aims to investigate the clinical and evolutionary characteristics of multifocal tuberculosis. It included 41 cases with tuberculosis collected between 1999 and 2013.

[Catastrophic antiphospholipid syndrome. Report of two cases].

The antiphospholopid syndrome has been associated with thromboembolic events, thrombocytopenia and fetal loss. Some patients with the antiphospholipid syndrome may develop an acutely catastrophic syndrome characterized by multiple vascular occlusions which often results in death. Most patients dye as a result of a combination of cardiac and pulmonary failure.
