Arms Assigned Interventions
Imiquimod 5%
Patients randomized to this arm will receive treatment with imiquimod 5%
Drug: Imiquimod 5%
Imiquimod 5% cream used three days a week for 4 weeks
Other Name: Aldara
Photodynamic therapy
Patients will be randomized to receive photodynamic therapy twice at a 2 week interval to the affected area.
Procedure: Photodynamic therapy
Photodynamic therapy involves applying Metvix cream to the affected area followed by illumination. It will be done twice during the study at a 2 week interval.
