Background. Merkel cell carcinoma of the head and neck is a rare and aggressive malignant tumour. Both the dermatological and surgical colleagues should be aware of this entity as lesions usually present on sun exposed areas of the skin such as the head and neck. Main Observation and Treatment. A 69-year-old male originally presented to the maxillofacial surgery department with a growing lesion on the left eyebrow. Histological analysis confirmed Merkel cell carcinoma and consequently surgical excision was carried out. A follow-up PET/CT scan 2 years later demonstrated a hotspot in the left parotid gland. Fine needle aspiration and cytology revealed Merkel cell carcinoma. A subtotal parotidectomy left side with ipsilateral selective neck dissection levels I to III was carried out. Conclusions. Potential secondary Merkel cell carcinoma in the head and neck region should be taken into account when planning short- and long-term follow up for previously diagnosed patients. This followup should involve both dermatological and surgical colleagues.
背景。头颈部默克尔细胞癌是一种罕见且侵袭性强的恶性肿瘤。皮肤科和外科医生都应了解这种疾病，因为病变通常出现在皮肤暴露于阳光下的区域，如头颈部。主要观察与治疗。一名69岁男性最初因左眉部不断增大的病变就诊于颌面外科。组织学分析确诊为默克尔细胞癌，随后进行了手术切除。两年后的随访PET/CT扫描显示左侧腮腺有一个热点。细针穿刺和细胞学检查显示为默克尔细胞癌。进行了左侧腮腺次全切除术及同侧I至III区选择性颈淋巴结清扫术。结论。在为先前诊断的患者制定短期和长期随访计划时，应考虑到头颈部区域潜在的继发性默克尔细胞癌。这种随访应由皮肤科和外科医生共同参与。
