• An asymptomatic skin nodule in a patient with myelofibrosis was shown to consist of extramedullary hematopoiesis. It was a soft bluish nodule that resembled a hemangioma. Microscopically, both erythroid and myeloid cells, but not megakaryocytes, were found. This case demonstrates the ability of the skin to recapitulate dermal hematopoiesis seen in a stage of human fetal development.
