Epidermoid cysts are benign lesions commonly seen in the head and neck region. Here, we describe the case of an epidermoid cyst in a 20-year-old man with a history of trauma presenting with a complaint of mass in the right cervical region. Upon closer examination, a 3cm long scar was noticed within the swollen region of the right submandibular area. MRI revealed a soft tissue mass involving the right neck and fine-needle aspiration biopsy showed that the content of the cyst was homogenous, confirming the diagnosis of epidermoid cyst. We used a pingyangmycin injection to manage the cyst with excellent short-term results, but the lesion reappeared after 3 months. The patient ultimately underwent surgical enucleation of the mass under general anesthesia.
