We report the case of a 25-year-old man with a maxillary ghost cell odontogenic carcinoma (GCOC). The patient presented to the maxillofacial and head and neck surgery clinic with a growing lump in the left maxilla. Initial workup with CT revealed a cystic lesion in the left upper jaw with associated bone erosion and an enhancing soft-tissue component. Enucleation showed a GCOC associated with a calcifying odontogenic cyst. After the diagnosis was obtained, the patient underwent widening of the first surgical resection. GCOCs are rare odontogenic neoplasms with unspecific clinical and imaging presentation, whose definitive characterisation is based on pathology. Current treatment approaches mainly involve surgical excision, but the prognosis is highly unpredictable due to intertumoral heterogeneity. As tumour recurrences occur in 73% of cases, radical surgery with negative margins is highly recommended. Therefore, it is essential to recognise this entity to offer patients adequate management.
我们报告了一例 25 岁男性上颌部幽灵细胞牙源性癌(GCOC)病例。该患者因左上颌逐渐增大的肿块就诊于颌面和头颈部外科诊所。初步 CT 检查显示左上颚有囊性病变,伴有骨侵蚀和增强的软组织成分。切除显示与钙化牙源性囊肿相关的 GCOC。诊断获得后,患者进行了第一次手术切除的扩大。GCOC 是一种罕见的牙源性肿瘤,具有非特异性的临床和影像学表现,其明确特征基于病理学。目前的治疗方法主要涉及手术切除,但由于肿瘤间异质性,预后高度不可预测。由于 73%的病例会出现肿瘤复发,因此强烈推荐进行有阴性切缘的根治性手术。因此,认识到这一实体对于为患者提供适当的治疗非常重要。
