Atypical Sweet's syndrome in a neutropenic patient with acute myeloid leukemia, secondary to a RAEB-T, simulating thrombophlebitis.

We report a rare case of a patient with acute myeloid leukemia following refractory anemia with excess of blasts transformed (RAEB-T) who presented a clinical picture suggestive of thrombophlebitis. The ultrasonographic procedure and the response to corticosteroid treatment suggest that this condition was compatible with an atypical Sweet's syndrome.
