**4. Conclusion**

LINCE® (MMOptics, São Carlos, SP, Brazil) device has become excellent commercial equipment for the PDT treatment for non-melanoma skin cancer in Brazil. Thereby, the development of an anatomical device with a larger illumination area becomes more efficient to treat extensive lesions.

The anatomical device was designed to optimize the PDT procedure in AK lesions scattered in a specific region of the body and in body sites, where a machine is required for the obtaining of the curvature according to the anatomy of the treated region. The device treated extensive lesions and reached their entire extension. It suffered no heating during treatments, therefore the thermal energy dissipation in this shape was more effective, and caused no sensation of thermal discomfort to the patient.

The anatomical device can be used for several dermatological clinical applications, including esthetic procedures for facial, body, and capillary treatments.

Further clinical tests will be conducted and, if necessary, the device will undergo modifications towards improvements in clinical procedures.
