Background. Spiradenocylindroma is an extremely rare entity composed by two distinct neoplasms in one lesion: spiradenoma and cylindroma. It may arose solitary or multiple, sporadic or familial and often affect the scalp. Surgical removal is curative and histopathological examination is mandatory for diagnosis. Aim. The aim of this article is to define the clinical features of spiradenocylindroma and its importance in the differential diagnoses of head and neck tumors. Case presentation. A 58 years-old female with a preauricolar painless, tender nodule presented to our attention. The patient underwent ultrasonography and MRI, which showed a non-specific cystic lesion. Surgery was performed and histopathological examination revealed a spiradenocylindroma. A 3-years disease-free follow-up was achieved. Conclusion. Spiradenocylindroma is often misdiagnosed and, in our study, we highlight its role in the differential diagnoses of head and neck masses.
