[Endobronchial presentation of an inflammatory myofibroblastic tumor]. / Présentation endobronchique d'une tumeur myofibroblastique inflammatoire.

INTRODUCTION: Inflammatory myofibroblastic tumors are a rare cause of primary lung tumors, most often solitary and in more than 50% of cases detected in individuals under 40 years of age. OBSERVATION: A 17-year-old patient consulted in pneumology for development of hemoptysis over a period of two weeks. Thoracic computed tomography revealed a left lower lobe cavity 24mm in diameter with bronchial fistulation and hydro-aeric level. Bronchial fibroscopy by mini-endoscope highlighted an endobronchial lesion in a subdivision of the sub-segmental posterior aspect of the left lower lobe. Paraclinical assessment highlighted a probable inflammatory myofibroblastic tumour. A surgical intervention was indicated and a lower left lobectomy performed. Histological analysis confirmed the presence of the tumour, which was resected in healthy margins by left lower lobectomy.
