Extramedullary hematopoiesis in cerebellar hemangioblastoma
Neurosurgery, 1991Abstract Extramedullary hematopoiesis and paraneoplastic erythrocytosis are uncommon in cerebellar hemangioblastoma, and their concomitant occurrence has not been reported. In a study of 26 cases of hemangioblastoma, we found extramedullary hematopoiesis in 4 tumors; one was associated with erythrocytosis.

Extramedullary Hematopoiesis in a Malignant Meningioma
Neurosurgery, 1983An unusual case of malignant intracranial meningioma is presented. The operative management was complicated by the abrupt development of fulminant brain edema and herniation. The tumor contained areas of extramedullary hematopoiesis, a finding not previously reported.

Tumefactive extramedullary hematopoiesis of the stomach
Gastrointestinal Radiology, 1976A 3 X 4 cm submucosal gastric mass of extramedullary hematopoeitic tissue occurred in a patient with chronic myelogenous leukemia. Such stomach masses have been misinterpreted as malignant tumor. Tumefactive extramedullary hematopoiesis of the stomach is an infrequent occurrence in patients with extramedullary hematopoiesis but should be considered in ...

Extramedullary hematopoiesis of the middle ear
American Journal of Otolaryngology, 1989A 22-year-old man with sickle cell disease developed a conductive hearing loss as a result of extramedullary hematopoiesis in the right middle ear. This is the first reported case of conductive hearing loss from extramedullary hematopoiesis and only the second report of extramedullary hematopoiesis in the middle ear.

Case 69: Extramedullary Hematopoiesis
Radiology, 2004A 66-year-old man was found to be anemic and thrombocytopenic during his annual physical examination. Work-up with bone marrow evaluation revealed mild marrow fibrosis with marked megakaryocytic hyperplasia, a finding that is consistent with early myelofibrosis with myeloid metaplasia. The diagnosis was confirmed with cytogenic study of the bone marrow.

Cutaneous extramedullary hematopoiesis.
Archives of dermatology, 1976An 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.

Cutaneous extramedullary hematopoiesis in myelofibrosis
Journal of the American Academy of Dermatology, 1990Erythematous papulonodules that resembled a malignant lymphoma developed in a 62-year-old man. Further examination revealed that he had primary myelofibrosis with cutaneous extramedullary hematopoiesis. All three marrow elements (myeloid, erythroid, and megakaryocytic series) were present in the skin lesions.
