“…2 This is similar to findings in Benin, where 51.8% of skin tumours were malignant. 15 The predominance of keratinocytic malignancies and squamous cell carcinomas in particular is in keeping with findings in Lagos, Kano and Zaria. 7,16,17 However, studies in Calabar documented that Kaposi Sarcoma was the commonest malignancy, while melanomas were the most frequent in Benin and Tanzania.…”

“…This is in contrast with observations in Kano (6 th and 7 th decades) but correlates with findings in Benin. 7,15 This overall late onset is due to the cumulative effects of UV radiation and other aetiologic agents. In India, Khandpur documented that the vast majority of skin tumours were benign.…”

“…This correlates with findings in Kano, Benin and Tanzania. 7,12,15 Lower limbs are usually exposed to UV radiation from the sun and are also a frequent site of chronic ulcerative lesions, which are a common precursor of skin malignancies. The paucity of lesions on the trunk and groin can be attributed to limited UV exposure and lower occurrence of trauma in comparison to the limbs.…”

Background: Skin cancers are the commonest malignancies in Caucasians but are relatively less common in dark skinned persons. They are strongly linked to ultraviolet exposure, skin melanin content, and immune status.Methods: This study reviewed all histologically diagnosed skin neoplasms at the Federal Medical Centre, Makurdi from January 2012 to December 2016.Results: A total of 84 neoplasms were seen, with 42 (50%) being malignant. Of the malignant lesions, Squamous cell carcinomas were the most frequent (45.2%), followed by melanomas (23.8%). The lower limb was the most frequent site of both benign and malignant neoplasms, while a male to female ratio of 0.88:1 was observed.Conclusions: A relatively high UV radiation intensity, combined with a predominance of outdoor agricultural based activities, alongside chronic ulcerative/inflammatory lesions and a high HIV burden all indicate a need for widespread enlightenment and screening campaigns to prevent occurrence of skin cancers and aid early diagnosis.

Most information on the harmful health effects of solar ultraviolet radiation (UVR) has been obtained in populations in which the majority has fair skin. Here a systematic review of evidence on diseases related to solar UVR in Africa was undertaken, and the appropriateness of effective photoprotection for these people considered. There are few population-based studies on UV-induced skin cancers (melanoma, squamous and basal cell carcinomas) in Africa, although limited reports indicated that they occur, even in people with deeply pigmented skin. The incidence of melanoma is particularly high in the white population living in the Western Cape of South Africa and has increased significantly in recent years. Cataract is extremely common in people of all skin colours and is a frequent cause of blindness, particularly in the elderly. For both skin cancer and cataract, the proportion of the disease risk that is attributable to exposure to solar UVR in African populations, and therefore the health burden caused by UV irradiation is unclear. There was little published information on the use of sun protection in Africa. The potential disease burden attributable to solar UVR exposure of Africans is high, although accurate data to quantify this are sparse. Information is required on the incidence, prevalence and mortality for the range of UVrelated diseases in different populations living throughout Africa. Photoprotection is clearly required, at least for those subpopulations at particularly high risk, but may be limited by cost and cultural acceptability.

Malignant Skin Tumors in Benin City, South-South, Nigeria

Abstract: Malignant melanoma was the most common skin malignancy in this study. However, an increasing incidence of all malignant skin tumors was observed. This was particularly noticeable with Kaposi sarcoma, which may be attributed to the increasing prevalence of HIV/AIDS in Nigeria.
