“…The risk of both SCC and BCC increases with increase in age and with cumulative sun exposure, being more so in former. 12 71.2% cases of SCC in our study developed in more than 50 years old age group. Head and neck was the most affected site accounting for 69% cases of SCC.…”

INTRODUCTIONCutaneous malignancies constitute one of the most common human malignancies. Annually, more than 400,000 people are diagnosed to have skin cancer. Etiology is related to various factors such as race, age, sun exposure and many other factors. Predisposing factors include individuals with a fair complexion, a ABSTRACTBackground: Cutaneous malignancies constitute one of the most common human malignancies. Annually, more than 400,000 people are diagnosed to have skin cancer. The skin cancers are classified into melanomas and non-melanoma skin cancers (NMSC). In India, skin cancers constitute about 1-2% of all the diagnosed cancers. The present study was undertaken on 41 patients presented to tertiary health centre to measure the frequency of cutaneous malignancies in our set up, analyse the demographic profile of the patients, assess the associated morbidity and mortality, formulate the treatment protocols and collect actionable evidence base for evolving useful strategies to address this emerging public health issue. Methods: Present study was carried out in the Department of surgical oncology, Sri Aurobindo Institute of Medical Sciences (SAIMS), Central India during the period from Jan 2015 to Dec 2017. The patients included in this study fulfilled the inclusion criteria which was first who presented with cutaneous malignancy confirmed by histopathology and surgical intervention. Results: Out of a total of 41 patients with various cutaneous malignancies, 53.7% (n=22) were males while 46.3 % (n=19) were females. The mean age was 53.92 years. There were 24 cases of SCC, 4 cases of BCC, 5 cases of malignant melanoma, two cases of malignant fibrous histiocytoma, two cases of sebaceous and one case each of dermatofibrosarcoma protuberans, epithelioma, capillary haemangioma and poorly differentiated carcinoma respectively. Face was the most frequent site of involvement (n=17), followed by trunk (n=6), scalp (n=5), lower limb (n=5), genital (n=4), upper limb (n=3) and neck (n=1). Conclusions: Cutaneous malignancies are not uncommon in our set up. In our set up, SCC constitutes the leading type. Painless skin lesion of a relatively long duration is the usual presenting feature. There is intense need of mass awareness and to impart knowledge about the medical and socioeconomic implications of this emerging health issue. This will not only help to prevent the avoidable causes but also prompt early medical consultation in case an individual develops such skin lesions.

Resumo: Este estudo aborda a dermatologia na pele negra. Inicialmente, discute os conceitos de raça e etnia, assim como os critérios de classificação da população brasileira, indicando as regiões em que a população negra se concentra. A seguir, faz breve explanação sobre os sistemas de classificação da cor da pele e descreve particularidades estruturais, biológicas e funcionais da epiderme, derme e anexos cutâneos que diferenciam as peles clara e escura. Posteriormente, mostra algumas alterações fisiológicas comumente observadas na pele, nas unhas e nas mucosas dos indivíduos negros. Aponta, também, alguns padrões de reações e modificações da cor das lesões, decorrentes da hiperpigmentação cutânea, que determinam aspectos inusitados às dermatoses, dificultando seu reconhecimento. Finalmente, destaca algumas doenças em especial, enfatizando particularidades inerentes ao padrão das lesões e à freqüência de algumas dermatoses na pele negra. Nesse contexto, a intenção foi fornecer dados para auxiliar o dermatologista a se familiarizar com as diferentes nuanças que as doenças podem adquirir na pele mais pigmentada.

Como o grau de pigmentação interfere sensivelmente na semiologia dermatológica, o reconhecimento das dermatoses nas peles mais escuras, mesmo aquelas mais comuns, pode ser um desafio na prática médica diária. Por isso, é necessário que o profissional se familiarize com as diferentes nuanças que as lesões podem adquirir na pele mais pigmentada. 1 RAÇAS E ETNIASO conceito relativo a "raças humanas" compreende as diferenças morfológicas entre os povos.

“…If a Negroid country such as Uganda is considered. this ratio is 285 to 1 (Davies et al, 1968) whereas in Caucasian countries this ratio is reversed; for instance in the United Kingdom it is 0 4 to 1 (Harnett, 1952) and in the U.S.A. it is 0 3 to 1 (Schreiber et al, 1971). In our series the ratio in the Sudan as a whole was 4-3 to 1, thus falling in between the Caucasian and Negroid ratios.…”

Summary.-Superficial cancer in the Sudan accounted for 17-2% of all malignant tumours examined histologically during the period 1962-72 inclusive. Of the 4 pathological types studied, squamous cell carcinoma was the commonest (63.3% of all superficial cancers) followed by malignant melanoma (18*8%) and basal cell carcinoma (14-9%) whilst Kaposi's sarcoma formed only 3%o of the total. Generally, twice as many cases occurred in males as in females, with the exception of Kaposi's sarcoma where all the patients were males. Although a relatively high proportion of cases occurred in the young age groups, the age-specific incidence was noted to increase with age. Similarities and differences in the anatomical site of tumours compared with European and African series were noted. Certain differences emerged in the geographical distribution of these tumours in the Northern and Southern regions of the Sudan-regions which differ both ethnologically and geographically-thus suggesting possible roles played by racial and environmental factors in this respect.
