Abstract: Myofibroblastoma is a soft tissue tumor that was originally described as a breast pathology in 1987 and is rarely diagnosed in the oral cavity.There is a considerable data encompassing the pathological features of myofibroblastoma of head and neck region, however, imaging findings are not as well documented.Moreover,no case of its occurrence in the posterior pharyngeal wall of the oropharynx has been reported so far. We describe the occurrence of this lesion in the posterior pharyngeal wall of the oropharynx in a young 17 years adult presenting with progressive dysphagia.This case report also reviews the imaging appearance, highlights the CT and MRI findings and summarizes the current diagnostic and management approach. Summary: The extra mammary location of the myofibroblastoma is rare. We describe the case of myofibroblastoma in the posterior pharyngeal wall of the oropharynx in 17 years adult presenting with isolated intermittent dysphagia.References: 1- Wargotz E, Weiss S, Norris H.
