title: [Therapy-resistant aggressive cystic lesion of the mandible].
abstract: Several extensive surgical interventions of a cystic lesion in the left mandible were followed by recurrences. The lesion extended from the primary mandibular region into the area of pterygopalatine fossa finally infiltrating the orbital region and the skull base. Histological results could never demonstrate a malignancy with certainty. Due to the patient's poor general condition, the refusal for further surgical inventions and due to the malignoma-like growth pattern radiation treatment was performed. However, this had no effect on tumor progression.
