Seromucinous hamartoma (SH) is a rarely seen benign polypoid mass of the sinonasal tract. Although the most common presentation symptom is nasal obstruction, most of the patients are asymptomatic. In this paper, the authors present an additional case of SH and discuss its differential diagnosis. A 34-year-old male patient presented with progressive nasal obstruction and serous nasal discharge for several months. A well-defined polypoid mass was detected in the left nasal cavity during the endoscopic assessment. Preoperative biopsy was reported as benign polypoid lesion. The mass was resected via transnasal endoscopic approach and final pathological examination was notified as SH.The SH is an uncommon tumor, originates from nasal septum in the most cases and presents as a well-circumscribed polypoid mass. Radiological imaging modalities and biopsy should be performed to distinguish from the sinonasal malignancies. Complete surgical excision is recommended treatment and recurrence is almost never.
