• Agnogenic myeloid metaplasia, one of the entities in the myeloproliferative syndrome, usually initially appears with splenomegaly, hepatomegaly, and a normocytic, normochromic anemia. Extramedullary hematopoiesis is also a common finding, but is exceedingly rare in the major salivary glands. We report a case of extramedullary hematopoiesis in the parotid gland and discuss the differential diagnosis and characteristics of the disease.
