Myelofibrosis with skin lesions.
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.
