ABSTRACT

Objective To investigate the value of image analysis technology of polari-light dermoscopy (PD) in diagnosing head and face tumors. Methods We randomly collected the head and face tumors from the patients in this hospital, and then diagnosed them with naked eyes and PD, respectively. After making sure the diagnosis by histopathology, we analyzed the results retrospectively. Results We summarized the diagnostic signs of 211 head and face tumors on dermoscopy, which shown a great specificity. Its diagnosis rate reached to 92.89 %, obviously higher than that (69.67 %)with naked eyes. Due to clinical misdiagnosis and erroneous treatment, the recurrence rate of skin lesions was 19.91 %. The top 3 of head and face tumors, in turn, was seborrheic keratosis, melanocytic tumor and basal cell carcinoma. Conclusions PD is a non-invasive image analysis technology, which is especially applicable to the early diagnosis of head and face tumors. It can make sense in decreasing blind biopsy, directing surgical excision areas effectively, and selecting reasonable remedy. It also has great significance in the recovery and beauty of skin lesions.
