Total scalp irradiation may be used to treat numerous conditions including squamous and basal cell carcinomas. These conditions are relatively uncommon and patients are frequently treated with palliative intent. In this report, we describe a volumetric arc therapy technique using photon beams for curative intent in an 84 years old patient with recurrent basal cell carcinoma of the scalp. Dose was 50Gy (2Gy
per session) to the planning target volume (PTV) followed by a 10 Gy boost to the macroscopic disease on the forehead. A custom made 1 cm superflab bolus helmet was used.

Toxicities only consisted of Grade-1 transient radiation dermatitis and alopecia. A sustained clinical response was observed at 6 months follow-up.

Volumetric arc therapy (VMAT) may offer an effective alternative modality to treat patients with very extensive scalp lesions as described in this case report.
