Drug Rash with Eosinophilia and Systemic Symptoms (DRESS) syndrome is a drug-induced hypersensitivity syndrome, characterized by rash, hyereosinophilia and multiorgan failure, including cytolytic hepatitis. ⋯ Amoxicillin/clavulanic acid, although rarely described in the literature, is a rare cause of DRESS syndrome. Severe cholestatic hepatitis associated with disabling pruritus may be one of the systemic manifestations, with a good prognosis using corticosteroids and plasma exchanges.

Case Reports
[Macrophage activation syndrome as the presenting manifestation of intravascular lymphoma].
Intravascular large B cell lymphoma is a neoplastic cell proliferation leading to the occlusion of the lumen of small vessels. This is a rare haematological malignancy, which is difficult to diagnose because of a heterogeneous clinical presentation. ⋯ Due to the polymorphism and the systemic presentation of intravascular large B cell lymphoma, the internist may be confronted with this disease, which is considered to be more severe if associated with a macrophage activation syndrome. Awareness of the intravascular large B cell lymphoma is important because the prognosis depends on the rapidity of the initiation of chemotherapy associated with rituximab.

Most of recurrent pericarditis are idiopathic and only 15 to 20% have a specific diagnosis. Primary pericardial mesothelioma is a rare cause of recurrent pericarditis. Diagnosis can be challenging and antedates patient's death in only 10 to 20% of cases. Histology of mesothelioma and immunohistochemistry are mandatory for the diagnosis. Median of survival before using pemetrexed was about 6 months after diagnosis. ⋯ This case report highlights the necessity of repeat pericardial biopsy in the case of adverse outcome.

Aortitis is a serious complication of giant cell arteritis (GCA), because of the risk of aortic aneurism, rupture, or dissection. Aortitis is present either at presentation or, more frequently, occurs as a delayed complication, typically as an aortic aneurism of the ascending part of the aorta. An aortic aneurism may occur in up to 10% of patients. ⋯ When present at the time of diagnosis of GCA, these findings seem to be associated with frequent relapses and perhaps with a higher long-term vascular mortality rate. Therefore, we recommend the screening of aortitis lesions at GCA diagnosis by an aortic CT-scan and follow-up. Therapeutic trials should be conducted to try to improve the treatment of aortitis in GCA.

Histiocytic necrotizing lymphadenitis (Kikuchi-Fujimoto disease) is a rare clinical entity characterized by the association of enlarged lymph nodes in the posterior cervical region and fever. The disease is more frequent in young women. ⋯ Kikuchi's disease should be suspected in an African patient when lymphocytic meningitis is associated with enlarged cervical lymph nodes, hemophagocytosis and HHV6 DNA integration.
