Pelvic extramedullary hematopoiesis

Abstract

Extramedullary hematopoiesis (EMH) is the result of a compensatory mechanism. EMH occurs more frequently in the liver and
spleen manifesting itself through several clinical hematological
disorders. Its association with other diseases is rare as well as
its rare forms of nonhepatosplenic location, in particular those
of pelvic location.
In this article the authors report a case of an EMH patient of
pelvic location related to an old pelvic fracture.
Despite the rarity, this case shows the need to consider EMH
in the differential diagnosis of tumors located outside the bone
marrow.
