title: Nodular hematopoiesis of the liver diagnosed by fine-needle aspiration cytology.
abstract: A case of tumor-like extramedullary hematopoiesis (EMH) of the liver diagnosed by fine-needle aspiration cytology guided by computer tomography (CT) is reported. The initial clinical diagnosis was metastatic carcinoma from an adrenal gland primary. Five other cases of tumor-like EMH diagnosed by FNA have been presented in the literature. In two of the cases, the primary clinical diagnosis was metastatic tumor. The most common location for tumor-like EMH is paravertebral and intrathoracic. Three such cases of paravertebral tumor-like EMH have been diagnosed by FNA. Nodular EMH can be found rarely in other organs as in the liver.
