A 45-year-old man presented with a history of chronic left nasal congestion. Nasal endoscopy revealed a pedunculated polypoid mass with glandular epithelium surface on the posterior nasal septum. Computed tomography revealed a 25-mm mass-like growth in the left posterior nasal cavity attached to the nasal septum with a stalk. The patient underwent transnasal endoscopic surgery, and the tumor was removed under a block with safety margin. The final pathological diagnosis was sinonasal seromucinous hamartoma (SH). Sinonasal SH is a rare tumor with only 31 reported cases. Transnasal endoscopic surgery is currently the first-line treatment for sinonasal SH. Differential diagnoses of this lesion include inflammatory polyps, respiratory epithelial adenomatoid hamartoma, and adenocarcinoma. Although SH is a benign tumor, its progression to adenocarcinoma has been reported. Therefore, unilateral posterior nasal tumors must be diagnosed precisely.
一名45岁男性，有慢性左侧鼻塞病史。鼻内镜检查发现后鼻中隔有一个带蒂的息肉样肿物，表面为腺上皮。计算机断层扫描显示左侧后鼻腔有一个25毫米的肿块样生长，附着于鼻中隔并有蒂。患者接受了经鼻内镜手术，肿瘤在有安全切缘的情况下整块切除。最终病理诊断为鼻窦浆液黏液性错构瘤（SH）。鼻窦SH是一种罕见肿瘤，仅有31例报道。经鼻内镜手术目前是鼻窦SH的一线治疗方法。该病变的鉴别诊断包括炎性息肉、呼吸上皮腺瘤样错构瘤和腺癌。虽然SH是良性肿瘤，但已有进展为腺癌的报道。因此，单侧后鼻腔肿瘤必须准确诊断。
