OBJECTIVES:
* Determine the clinical response, by serial objective measurements, in patients with melanoma treated with boron neutron capture therapy.
* Determine the time course, uniformity, and severity of acute dermal reactions in patients treated with this regimen.
* Determine the late dermal reactions in patients who are followed for at least 6 months after treatment with this regimen.
* Determine the pharmacokinetics of this regimen in these patients.
OUTLINE: Patients are stratified according to tumor size (no greater than 15 cc vs greater than 15 cc).
Patients undergo boron neutron capture therapy.
Patients are followed for 3 years.
PROJECTED ACCRUAL: A total of 36 patients will be accrued for this study within 3 years.
