Case report: chronic inflammatory ulcer and osteoradionecrosis of the skull following radiotherapy in early childhood.

INTRODUCTION

Chronic inflammatory diseases of the skin are the most common differential diagnosis of tumorous lesions of the craniofacial region. Detailed information about a patient's medical history is important for the clinical diagnosis of such cases. Previous radiotherapy should be taken into account, especially in cases of chronic dermatitis, since complications include osteoradionecrois of the adjacent bone strucutres with surrounding inflammation.

CASE REPORT: We present the case of a 77-year-old femal patient who was admitted to our department with a slightly progressive ulcerating lesion of the frontotemporal skull. The patient had received radiotherapy in early childhood as primary therapy for hemangioma. Diagnostic imaging and biopsies revealed a diagnosis of chronic ulceration with underlying osteonecrosis and fibrotic osteomyelitis of the skull. A complex reconstruction of osseous structures and soft tissue was necessary to resolve her complaints.

CONCLUSION

Chronic radiodermatitis and osteoradionecrosis in adults, occurring as late complications, are uncommon, but can be observed even nearly 80 years after radiation. Large defects of the skull require a complete reconstruction to avoid several complications.
