Background and Aim: Skin cancer is the most common type of cancer constitutes and 75% of all cancers in the world. Malignant melanoma is the most invasive and lethal form of skin cancer. The objective of this study was to evaluate infrared thermography in differentiation of benign and malignant skin lesions. Methods: This study was conducted on 120 patients (60 female, 60 male) with a lesion suspicious for melanoma and identifying the type of lesion (benign or malignant) based on thermal model using Fuzzy C-Means (FCM) clustering. In this imaging method, the difference on temperature responses between the normal and abnormal tissue was compared and data obtained was compared with biopsy results. Results: In 120 cases studied, 3 cases of skin cancer (2 male, 1 female) were found which all could be detected based on analysis of thermal images. Conclusion: At present, new methods for the detection of skin cancer, especially non-invasive diagnostic tools, have been discovered in several laboratories. The method presented in this paper could be considered as a non-invasive and cost effective method for the detection of skin cancer.

Background and Aim: Malignant melanoma is one of the most dangerous types of skin cancer. The aim of this study was to evaluate Spatial Thermographic Imaging (STI) in differentiating benign from malignant skin lesions.

Methods: One-hundred and ten STI images were taken from the volunteers who had lesions being suspected for malignant melanoma. Benignity or malignancy of lesions was determined according to the changes detected in tissue using texture filters. The STI data were compared with histopathology results.

Results: Out of 110 investigated patients with STI, three cases of malignant melanoma were found. Two cases were in men and the other one was in a woman. Accuracy of STI in diagnosis of malignant melanoma was 98%.

Conclusion: STI may potentially be used as a non-invasive method for the detecting skin malignant melanoma.
