Abstract
Multiple surgical methods are available for the management of malignant melanoma. Often, these methods have limitations in terms of the ability of obtaining margin clearance in the context of an appropriate cosmetic outcome. This article, briefly reviews the use of different simple and excisional techniques as well as that of Mohs micrographic in the surgical management of malignant melanomas

Abstract
N-acetylcysteine (NAC) is the acetylated metabolite of cysteine and is approved by the Food and Drug Administration (FDA) for treating acetaminophen toxicity. By boosting glutathione, NAC acts as an antioxidant and through replenishing glutathione, it can also prevent paracetamol toxicity. From the other hand, NAC has mucolytic and antiinflammatory effects and also is a glutamate precursor and therefore can be used in a variety of diseases. Regarding the various pharmacological effects of NAC and its low rate of adverse events, NAC has attracted increasing interest for a range of indications during the recent years. Here, the possible applications of this drug in dermatology are reviewed.

Abstract
Background and Aim: Skin cancers are one of the most common malignancies in the world and create a high rate of morbidity but low rate of mortality with the exception of malignant melanoma that has a high mortality rate. In recent decades, incidence of skin cancer has been increased. The most important risk factors are sunlight and skin type. The aim of this study was to evaluate the frequency of skin cancers in patients who were admitted to Sina Hospital of Hamedan during a 17-year period.
Methods: In this cross-sectional study, 951 patients with different types of skin cancer, entered in the study. For each patient, data related to age, gender, location, occupation, pathologic type of cancer and site of skin involvement, were collected.
Results: The mean age (mean±standard deviation) of patients was 61.6±15.3 years (2-100 yrs) and most of them (67.2%) were males and workers (%38). The most common pathologic types of skin cancer were basal cell carcinoma (BCC) (59%) and squamous cell carcinoma (SCC) (29%). The most frequent site of tumor expression was face (61.2%) and the least frequent involved site was genitalia (0.4%).
Conclusion: This study showed that skin cancer is more common in males, old patients and workers. It was more common on the face. Screening program for detection of this disease at an earlier stage of elderly men especially in sun exposed occupations is recommended.

Abstract
Background and Aim: Malignant melanoma is one of the most lethal skin tumors. Its prevalence and demographic specifications are different in European and western countries from those in the Middle East. This study was aimed to evaluate the demographic and clinical characteristics of malignant melanoma in Iran.
Methods: In this cross-sectional study, the patients with the diagnosis of malignant melanoma who atteneded the tumor clinic of Razi Hospital, Tehran, Iran were included. Demographic and clinical data were registered in specific questionnaires. Histopathology findings were also recorded in the questionnaires.
Results: A total of 2500 patients attending tumor clinic of Razi Hospital were evaluated. Out of them, 166 cases had malignant melanoma including 89 (53.6%) females and 77 males (46.4%). The mean age of patients 60.5 years. History of chronic sun exposure was found in 65 (39.2%) cases. Mean delay time between commencement of lesion and diagnosis was 9 months. The most common histopathologic type was acral lentiginous and the most common observed stage of tumor was Clark 3. The most common frequent observed tumor site was head and neck which was followed by limbs.
Conclusion: Malignant melanoma is common in patients with skin tumors in Iran. Considering morbidity and mortality of malignant melanoma and the relatively high stages of tumors, at the fist time the patients sought medical care, screening programs seems to be necessary to find the patients in earlier stages, as well as the mass education. Some of our findings such as the most common location of the tumors, family history and relation with dysplastic naevies, remain to be confirmed in studies with larger sample sizes.

Abstract
Background and Aim: Malignant melanoma is a rare and most malignant type of skin cancer which is originated from melanocytes. It is capable of infiltrating into interior organs and could cause mortality. The aim of this study is to analyze the survival of patients with malignant melanoma according to their age, gender, mitosis count, tumor thickness, level of lymphocyte infiltration, tumor location and the stage of the tumor.
Methods: This is a descriptive-analytical study which has been done on, the data of 61 patients with malignant melanoma registered in pathology laboratory of Shahid Sadoughi hospital, Yazd. A questionnaire was used to collect the data via phone call, examining pathology slides and reviewing patients information.
Results: The average survival time was 61.09±6.12 months.The mean age of the patients was 67.9±6.0 with the range of 18 to 89 years. Stage Ι had the best and stage ΙΙΙ and VΙ had the worst prognosis. The best survival rate was seen in malignant melanomas located on trunk, head and neck. Malignant melanoma of extremities had the worst prognosis. There was a statistically significant relationship between survival rate and stage (P=0.033) as well as the location of the tumor (P=0.0421).
Conclusion: The survival of patients with malignant melanoma in Yazd had a statistically significant relationship with stage and the location of tumor but there was no significant relationship with mitosis count, gender, age, tumor depth and lymphocyte infiltration.

Abstract
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.
