Extramedullary plasmacytoma (EP) is a rare neoplasm characterized by monoclonal proliferation of plasma cells without features of multiple myeloma. EP constitutes 3% of all plasma cell tumors. Most of the cases of EP occur in the head and neck regions, especially in the aerodigestive tract. We present a case of recurrent epistaxis for 6 months and extensive workup revealed EP of the right nasal cavity. Primary care physicians and otolaryngologists should be aware of this very rare but a plausible cause of epistaxis and keep EP in the differential diagnosis of recurrent epistaxis.
髓外浆细胞瘤(EP)是一种罕见的肿瘤,其特征是浆细胞单克隆增殖,无多发性骨髓瘤的特征。EP 占所有浆细胞瘤的 3%。大多数 EP 病例发生在头颈部,特别是在呼吸道。我们报告了 1 例反复发作性鼻出血 6 个月的病例,广泛的检查显示右侧鼻腔 EP。初级保健医生和耳鼻喉科医生应该意识到这是一种非常罕见但可能引起鼻出血的原因,并将 EP 纳入复发性鼻出血的鉴别诊断中。
