title: Myelofibrosis with skin lesions.
abstract: An elderly male patient with primary myelofibrosis developed many papules on the trunk and later numerous subcutaneous nodules on the face. Histologically these lesions showed the features of extra-medullary haematopoiesis consisting of all the three components, i.e. myeloid, erythroid and megakaryocytic elements, findings never reported in the skin.
