Inflammatory pseudotumor, fibrohistiocytic type, also called benign fibrous histiocytoma, is a rare reactive entity usually found incidentally on routine chest roentgenography. We present a case of inflammatory pseudotumor, fibrohistiocytic type, initially diagnosed by fine‐needle aspiration (FNA) cytology in a 39‐yr‐old woman with a history of breast carcinoma. Cytomorphologic characteristics were confirmed by a cell block examination and immunohistochemical findings. The differential diagnoses of the fine‐needle aspiration cytology of this type of inflammatory pseudotumor are discussed. Diagn. Cytopathol. 1998:19:216—220. © 1998 Wiley‐Liss, Inc.
