Intrathoracic and pelvic extramedullary haematopoiesis in sickle cell disease: a case report.

Intrathoracic extramedullary haematopoiesis is a rare entity encountered in patients with long standing anaemias such as thalassaemia and congenital spherocytosis. It is rare in patients with homozygous sickle cell disease; only 11 cases of intrathoracic and two cases of pelvic extramedullary haematopoiesis have been documented in the literature. We report the case of a 30-year old man with homozygous sickle cell disease with intrathoracic and pelvic extramedullary haematopoiesis, the first case to be documented from the Caribbean.
