Abstract
BACKGROUND

Ghost cell odontogenic carcinoma (GCOC) is a rare malignant odontogenic epithelial tumor with features of benign calcifying odontogenic cysts. Herein, we report two new cases of GCOC and systematically review the previous literature.

CASE SUMMARY

In case 1, a 46-year-old man complained of painless swelling of the right maxilla for 3 years, with a 1-mo history of hemorrhinia in the right nasal cavity. In case 2, a 72-year-old man was referred to our hospital with a chief complaint of painful swelling of the right mandible. Initially, the preliminary diagnoses were ameloblastomas. Thus, the two patients underwent resection of the tumor under general anesthesia. Finally, immunohistochemical examination confirmed the diagnosis of GCOC. The patient in case 1 was followed for 2 years, with no evidence of recurrence. However, the patient in case 2 was lost to follow-up.

CONCLUSION

GCOC is a rare malignant odontogenic epithelial tumor with high recurrence. Local extensive resection is necessary for the definitive treatment of GCOC.

Core tip: Ghost cell odontogenic carcinoma (GCOC) is a rare malignant odontogenic epithelial tumor with features of benign calcifying odontogenic cysts. Herein, we report two cases of GCOC and describe their clinical features, histological characteristics, and treatment. In addition, the tumor affected the tooth, suggesting that the disease may originate from an odontogenic tumor, progressing to malignant GCOC. Moreover, we analyze the reported cases in the English literature and summarize the prognosis and optimal therapy.
