Endobronchial Malignant Fibrous Histiocytoma: A Case Report of an Unusual Presentation and Palliative Flexible Bronchoscopic Resection

Abstract

Primary malignant fibrous histiocytoma (MFH) of the lung is a very rare neoplasm, which usually presents as a parenchymal mass. Here, we report an unusual case of primary MFH of the bronchus showing relatively benign clinical features. We performed a palliative resection via flexible bronchoscopy using a polypectomy snare. The patient has survived for over 2 years of being diagnosed with an endobronchial mass, later found to be MFH, and 14 months post-debulking. There is a possibility that endobronchial MFH has a more favorable prognosis than MFH of other origins. If this is true, interventional bronchoscopy can be a reasonable option for non-operable cases of MFH.
