Objective To report the clinical and pathological features, immunohistochemistry, imaging features and differential diagnosis of one case of extramedullary plasmacytoma in the retropharyngeal space to improve the understanding of this disease. Methods The histopathological observation, immunohistochemistry and imaging examination of the extramedullary plasmacytoma in the pharynx of the pharynx were carried out. The clinical manifestations, pathological features, imaging characteristics and treatment were discussed in combination with the literature. The results of pathological diagnosis of plasma cell tumor. Magnetic resonance showed that the size of 16 cm × 8 cm. Patients due to financial constraints to give up treatment 1 month after follow-up, died of dyspnea. Conclusions Very rare pharyngeal space giant extracerebral plasmacytoma may be progressive dysphagia and upper airway obstruction as the main performance, timely diagnosis and appropriate treatment is conducive to obtaining a good prognosis.
