case_images: A 63-year-old male patient was admitted to our department on December 25, 2017, with a "left neck mass found for 3 years." The mass was approximately 6 cm in diameter with clear boundaries, protruding from the skin, hard and poorly mobile (Figure 1A), and no enlarged lymph nodes were palpable on the clavicle area behind the ear. According to the CT report, there was a 26 x 18 x 37 mm mass occupying the left upper neck below the parotid gland (Figure 1B), which was considered branchial cleft cyst with infection.

case_images: Pathological examination microscopically revealed highly differentiated squamous cell carcinoma of the left soft palate infiltrating the transverse muscle (Figure 4A). Microscopically, heterogeneous cells were seen under the squamous epithelium in the form of nesting sheets, with varying cell sizes, increased nucleoplasm ratio, thickened chromatin, eosinophilic nuclei and nuclear fission images, and localized keratinized bead formation (Figure 4B).
