title: Extramedullary hematopoiesis in a pyogenic granuloma.
abstract: Extramedullary hematopoiesis is rare outside the setting of significant primary hematologic disease. We describe this phenomenon in an exuberant pyogenic granuloma in an otherwise healthy man. We postulate that this vascular lesion provided a suitable milieu for homing and proliferation of stem cells.
