cording to histopathological characteristics. One is composite tumor, and the other is collision tumor. Composite tumor is a lesion showing the combined histopathological characteristics of two or more previously recognized tumor and/or cysts of different categories. Two constituent parts are mixed with each other, and histological transition is often observed. On the other hand, collision tumor is a lesion showing the independent histopathological characteristics of two or more previously recognized tumor and/or cysts of different categories. Two constituent parts are separated each other by connective tissue, and histological transition is not observed. Their origin is still unclear. In this study, a collision tumor was reported. 77-year old woman was referred to CNUH with a neck mass in right submandibular area. Incisional biopsy was carried out, and the patient was diagnosed as collision tumor of squamous cell carcinoma and neurofibroma. After reviewing studies reporting collision tumor from head and neck area, formation of a collision tumor was most frequent from a cervical area and average age is 59.6. A collision tumor commonly lead to misdiagnosis, and the prognosis is not always transparent. The variety symptom of collision tumor has to be kept in mind in the diagnosis and treatment of the lesions in head and neck area.
