“…Notably, only about 25% of all melanomas are diagnosed by physicians, with the remainder discovered by the affected individuals [17]. In particular, general physicians represent the first-line health care providers between patients and referral centers [18, 19, 20, 21, 22, 23, 24, 25, 26, 27] and need to be confident with the management of PSL, and in particular with the accurate diagnosis of melanoma.…”

Background: Dermoscopy used by experts has been demonstrated to improve the diagnostic accuracy for melanoma. However, little is known about the diagnostic validity of dermoscopy when used by nonexperts. Objective: To evaluate the diagnostic performance of nonexperts using a new 3-point checklist based on a simplified dermoscopic pattern analysis. Methods: Clinical and dermoscopic images of 231 clinically equivocal and histopathologically proven pigmented skin lesions were examined by 6 nonexperts and 1 expert in dermoscopy. For each lesion the nonexperts assessed 3 dermoscopic criteria (asymmetry, atypical network and blue-white structures) constituting the 3-point method. In addition, all examiners made an overall diagnosis by using standard pattern analysis of dermoscopy. Results: Asymmetry, atypical network and blue-white structures were shown to be reproducible dermoscopic criteria, with a kappa value ranging from 0.52 to 0.55. When making the overall diagnosis, the expert had 89.6% sensitivity for malignant lesions (tested on 68 melanomas and 9 pigmented basal cell carcinomas), compared to 69.7% sensitivity achieved by the nonexperts. Remarkably, the sensitivity of the nonexperts using the 3-point checklist reached 96.3%. The specificity of the expert using overall diagnosis was 94.2% compared to 82.8 and 32.8% achieved by the nonexperts using overall diagnosis and 3-point checklist, respectively. Conclusion: The 3-point checklist is a valid and reproducible dermoscopic algorithm with high sensitivity for the diagnosis of melanoma in the hands of non-experts. Thus it may be applied as a screening procedure for the early detection of melanoma.

“…Nevi are generally benign and very scarcely transform to skin cancers (especially CMM), and in such a case congenital nevi pose the highest and common moles with the lowest risk of transformation (1-15%) (1-3, 15). Skin malformations are easily visible even with untrained-bare eye.…”

BackgroundSkin cancers are the most common cancers around the world. Cutaneous malignant melanoma (CMM) is the malignancy of melanocytes that are mainly located in the skin and mucous membranes.ObjectiveThis study tried to evaluate the incidence and mean survival time of cutaneous malignant melanoma (CMM) in Yazd, Iran. It seems that the epidemiology and clinical aspects of CMM in Iran are different from those in other parts of the world; also due to the limited and scattered studies there isn't lot in the literature regarding CMM in Iran.Materials and MethodsThis study used data obtained from the cancer registry center in the province of Yazd for a period of 21 years (1988 – 2008). Population and statistical data were gathered from “National Organization for Civil Registration”. Population-based data were analyzed, focusing on the incidence and mean survival time over this 21 year period.ResultsThe mean incidence rate for CMM in Yazd-Iran between 1988 and 2008 was 0.40 per 100,000 for males and 0.27 per 100,000 for females per year, and the incidence of CMM was relatively constant during this period of time. The mean survival rates for women were better than men (80.5% and 76.3% respectively).ConclusionsCMM in Yazd is a low-incidence skin tumor that shows a relatively fixed incidence between 1988 and 2008, Higher incidences of CMM were found in sun-exposed areas (especially head and neck areas), with more incidence in men. Skin cancers and CMM incidence in Iran is lower than western countries, most probably due to geographical zone, genetic factors, skin type, society-related customs including clothing styles.

“…In terms of incidence age, the emergence of skin cancer is more common and probably in the sixth and seventh decades of life. [6262728293031] The incidence rate of BCC at the age of 40–79 years is 95%. [32] According to Collins et al 's study, the mean age of patients suffering from BCC is 64 years in the Netherlands, which is consistent with the findings of this study.…”

Introduction:Skin cancer, the melanoma type of which causes high mortality, is the most common malignancy in Iran and all over the world. UV is the most important cause of the incidence of this disease. This study evaluates the frequency of different types of cancer and their trajectory in Ilam province from 2012 to 2011.Materials and Methods:This analytical–descriptive study covered and evaluated all skin cancer patients who were registered in Ilam Province Cancer Registry during 20002 to 2011. Required information of each individual patient, such as age, sex, residence, pathological type of skin cancer, the location of the incidence of the disorder, and the year, was collected and studied.Findings:Out of total 347 cases, 240 cases (69.2%) were diagnosed with basal cell carcinoma (BCC), 63 cases (18.2%) with squamous cell carcinoma (SCC), 16 cases (4.6%) with malignant melanoma (MM), 8 cases (2.3%) with metastatic cancer, and 20 cases (37.7%) with other skin cancers. Mean age of patients was 62/42 ± 16/11 years, and the majority of them (37.7%) were men and lived in the city. Face was the most common place of the incidence of this disease (81.6%) and hand was the least common one (1.7%). The rate of incidence of cancer has experienced considerable growth in men and a slight decrease in the case of women between 2002 and 2011 in Ilam.Conclusion:According to the results of this study, the rate of skin cancer has increased among men during the studied period; thus, necessary measures are required to prevent and reduce the incidence of this disease, especially in people who are exposed to the sun's ultraviolet rays because of their jobs.
