Aggressive Recurrent Odontogenic Ghost Tumor with Cranial Invasion. %R %X Calcifying odontogenic cyst (COC) is a unique odontogenic lesion with combined features of a cyst and neoplasm.  This lesion shows a great diversity in its clinicopathological behavior.  It may become aggressive and rarely malignant.  This case is an aggressive COC of the maxilla in a young male patient which recurred after several radical surgical excisions.  Eventually invading the cranium, the lesion neither responded to surgical excision nor to radiotherapy. %U https://ijms.sums.ac.ir/article_40281_56e2b710eebe2c8ea7a7e6ff0ca830fb.pdf
