Abstract |
Human papillomavirus (HPV)-related multiphenotypic sinonasal carcinoma is a peculiar sinonasal tract tumor that demonstrates features of both a surface-derived and salivary gland carcinoma. Implicit in its name, this tumor has a consistent association with high-risk HPV, particularly type 33. It was first described in 2013 under the designation of HPV-related carcinoma with adenoid cystic carcinoma-like features. However, since its initial description additional cases have emerged which demonstrate a wide morphologic spectrum and relatively indolent clinical behavior. Herein we report our experience with a case of HPV-related multiphenotypic sinonasal carcinoma that was initially classified as adenoid cystic carcinoma in the 1980s. The patient recurred after a 30-year disease free interval. RNA in situ hybridization confirmed the presence of high-risk HPV in both her recurrence and her initial tumor in the 1980s, which allowed for reclassification as HPV-related multiphenotypic sinonasal carcinoma. Our case adds to the literature of this relatively newly described entity and supports the indolent clinical behavior of this neoplasm but also demonstrates a potential for very late local recurrence. |
