[Cutaneous vasculitis during primary myelofibrosis].

A leukocytoclastic cutaneous vasculitis in the course of an idiopathic myelofibrosis is reported. The cutaneous lesions that might appear in this hematological disease are discussed, including cutaneous infections, myeloid metaplasia and cutaneous infiltration due to the myeloproliferative process. We point out the rarity of cutaneous vasculitis during the course of primary myelofibrosis.
