This study is to compare the ability of optical biopsy. Research can use light enters the skin, collected, analyzed by the computer, and a picture created for the pathologist to conventional histologic examination compare with the pathologist looking at the piece of tissue through a microscope makes the diagnosis.

Enrollment: 113
Study Start Date: June 1999
Study Completion Date: July 2008
Primary Completion Date: June 2008 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Optical Biopsy
Optical Biopsy imaging
Device: Optical Biopsy imaging
Optical Biopsy imaging

Detailed Description:
The Optical measurements provide quantitative optical property values that reflect changes in tissue perfusion, oxygen consumption, and cell/matrix development. Each measurement requires less than 5 minutes to execute. The measurements will be taken before and after skin treatment.This non-invasive, non-contact technique has great potential as a means to diagnose different skin problems without the need to obtain a piece of tissue from the skin.
