“…In Iran limited studies have been accomplished, with estimated incidence of 0.3 new cases of CMM per 100,000 per year (23). This study is consistent with the previous results indicating that the incidence of CMM is much lower compared to Non-Melanoma Skin Cancers (NMSCs).…”

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.

Desert dermatology describes the cutaneous changes and the diseases affecting those living in the desert. Diurnal variation in temperature is high and is characteristic of the deserts. The lack of water affects daily activities and impacts dermatological conditions. Adaptation to the desert is, therefore, important to survival. Infections are the most common conditions seen among this population, and among them, fungal infections are the most common. The high incidence of these infections would be accounted for by the poor hygienic conditions due to lack of bathing facilities due to scarcity of water and the consequent sweat retention and overgrowth of cutaneous infective organisms. Pigmentary disorders, photodermatoses, leishmaniasis, and skin tumors are found to be more prevalent in this region. Desert sweat dermatitis was another specific condition found to have an increased incidence. The environment of the desert provides for a wide variety of dermatoses that can result in these regions with few of these dermatoses found in much higher incidence than in other regions.

“…(Kumar, Abbas, & Aster, 2015;Natalie & Wen-Qing, 2017) The underlying causes are not known yet, although host and environmental are the most important factors such as exposure to ultraviolet radiation and geographic localization, family history of melanoma, immunosuppression and also, type 2 of diabetes mellitus slightly increase the risk of developing Melanoma. (Moslehi, Zeinomar, & Boscoe, 2018;Allam, Serrano, Serrano, Abd Elaziz, Del Castillo, & Navajas, 2015;Qi et al, 2014;Rahnama, Meymandi, & Nasiri, 2010) Important warning signs are: 1. asymmetry 2. irregular borders 3. variegated color 4. increasing diameter 5 millimeters 5. evolution or change over time. (Habif, 2011) Skin biopsy should be done for all suspected patients, and they should have a careful follow up for early detection of new tumors or metastasis (Natalie & Wen-Qing, 2017).…”

“…But we have so many different locations for this cancer, for instance, most common site for people in Yazd (a city in the center of Iran) were head and neck but in Fars the most common site was the foot. Also, findings in Kurdistan shows that the rate of survival for patients was low (50% for three years) and it is very different from Europe, Unites States (70-86% for five years) or even other cities of Iran like Yazd (Ahmadi, Asadi-Lari, Amani, Saeid, & Solaymani-Dodaran, 2015;Rahnama, Meymandi, & Nasiri, 2010;M.

Background: Melanoma is the most deadly of all skin cancers in the world, its incidence rate has increased in the last decades. We aim to define the frequency, and epidemiologic features of Cutaneous Malignant Melanoma Cases diagnosed between 2011 and 2016 in teaching hospitals of Shiraz University of Medical Sciences, southwest of Iran. Materials and Methods: This descriptive cross-sectional study was have performed at hospitals affiliated with Shiraz University of Medical Sciences from 2011 to 2016. Pathology reports collected from the laboratory along with general information such as age, sex, site of the tumor and had ulceration or not. SPSS version 23 statistical software was used for data analyzing. P-values less than 0.05 were considered significant. Results: A total of 183 cases of Cutaneous Malignant Melanoma were registered in Faghihi Teaching hospital, 7 cases in Namazi Teaching Hospital and 6 cases in Motahari clinic in Shiraz, between 2011 and 2016. The average age was 64.5 years with age range of 1year to 89 years, mostly in women (51.5%) and also most of the tumor sites were in the foot 46 (23.5%) and then in the scalp 20 (10.2%). The incidence of ulceration was 41 (20.9%), and the most common stage of the tumor was stage one. Conclusion: The results proved the importance of awareness of the physicians about the frequency and epidemiologic features of Cutaneous Malignant Melanoma in their region that they can diagnose or screen and treat them more earlier in better ways.

Cutaneous melanoma in a desert climate zone: a retrospective study of 125 cases

Abstract: This study indicates that some demographic and histopathologic features of CM in this population differ from those in the literature. More studies including cohort studies are needed to fully describe the nature and survival rate of CM in this area.
