Sinonasal teratocarcinosarcoma: a case report and literature review

BACKGROUND: Sinonasal teratocarcinosarcoma (SNTCS) is a highly invasive malignant tumor most frequently found in the nasal cavity and paranasal sinuses. As a result, it can be confused with other sinonasal tumors. In addition, SNTCS progresses rapidly and often infiltrates other tissues or organs in the early phase, resulting in poor patient prognosis. The objective of this article was to report the case of a patient with SNTCS and discuss the management strategy. Furthermore, we conducted a literature review for SNTCS and summarized the findings from 107 cases. Case presentation: Here, we report a 47-year-old man diagnosed with SNTCS and treated with radiochemotherapy after an initial operation. After follow-up for 5 years, no tumor recurrence was observed. CONCLUSIONS: As SNTCS progresses rapidly, early diagnosis and surgical treatment combined with radiochemotherapy can improve patient survival.
