Sweet syndrome associated with acute myelogenous leukemia. Atypical form simulating facial erysipelas

A case of Sweet syndrome in a patient with an acute myelomonocytic leukemia is reported. It is an unusual case simulating a facial erysipela. This case illustrates the difficulty in differentiating infection from Sweet syndrome in an immunocompromised patient. The negative cultures, ineffective antibiotics, and histopathologic examination results allowed the onset of corticosteroid therapy. The phagocytic function of the neutrophils studied by chemoluminescence was normal in the patient. The physiopathology of Sweet syndrome is discussed, in particular the role of cytokines in the accumulation of granulocytes.

[Echocardiographic aspects of multiple myxoma in Carney's syndrome]

In Carney's syndrome, the association of cardiac myxomas, spotty pigmentation and endocrine over activity, the myxomas are usually multiple and have atypical locations. The authors report a case in which an accurate diagnosis of these multiple myxomas was made by transoesophageal echocardiography, although transthoracic echocardiography had missed the diagnosis.
