[Venous thrombosis, unrecognized complication of DRESS]. / Thrombose veineuse, complication méconnue du DRESS.

BACKGROUND: DRESS (Drug Reaction with Eosinophilia and Systemic Symptoms) is a rare syndrome triggered by an immunological reaction to certain drugs and which may be life-threatening as a result of the onset of severe organ involvement. It is characterised by a long period from the time of drug therapy to the onset of actual signs. Herein, we report the case of 42-year-old female patient who developed DRESS one month after beginning allopurinol treatment. PATIENTS AND METHODS: A 42-year-old woman was hospitalised for febrile exanthema with facial oedema, polyadenopathy, mononucleosis syndrome, major hypereosinophilia and hepatic cytolysis. A diagnosis was made of DRESS with a RegiSCAR score of 5. The implicated drug was allopurinol, which had been initiated one month earlier. HHV-6 IgM serology was positive. Two days after the start of systemic corticosteroids, the patient developed thrombosis of the internal jugular vein. Other than major hypereosinophilia, no other factors favouring thrombosis were detected. A favourable outcome was achieved under effective anticoagulants and corticosteroids. DISCUSSION: They have been rare reports of venous thrombosis during DRESS. Hypereosinophilia can be involved in the onset of this condition. Prophylaxis with systemic anticoagulants may be necessary in DRESS involving major hypereosinophilia.

[Mucormycosis: an unusual cause of unilateral exophthalmia]. / La mucormycose : une cause rare d'exophtalmie unilatérale.

Mucormycosis is an invasive fungal infection associated with high mortality. Orbital involvement was usually reported but was rarely isolated. We report the case of a 57-year-old patient who presented a proptosis associated to an ethmoid sinusitis. Inflammatory symptoms were late which was responsible for delayed diagnosis. Our patient died because of multi-organ failure.
