Summary
Skin cancers occur in black Africans, with malignant melanomas on the feet and squamous cell carcinomas elsewhere being common. This study highlights the need for increased awareness and research into skin cancer in this population.
Area of Science:
- Dermatology
- Oncology
Background:
- Skin cancers are uncommon but present in black African populations.
- Existing literature on skin cancer in black Africans is limited, indicating a need for further investigation.
Purpose of the Study:
- To analyze the incidence, types, and locations of malignant skin tumors in black Africans.
- To raise awareness about skin cancer risks in populations with higher melanin content.
Main Methods:
- Retrospective analysis of 18 cases of malignant skin tumors.
- Data collected from the University of Port Harcourt Teaching Hospital between 1984 and 1987.
- Analysis included diagnoses, tumor site, patient sex, and age.
Main Results:
- Malignant melanomas (39%) were exclusively found on the soles of the feet.
- Squamous cell carcinomas were also observed in 39% of cases, with widespread distribution.
- Basal cell carcinomas (22%) occurred on the face.
- Three albinos in the study all developed squamous cell carcinomas.
Conclusions:
- Melanin offers some protection against sun-induced skin cancers, but it does not eliminate risk.
- There is a critical need for renewed interest and research into skin cancers within black African populations.
- Public health initiatives and clinical vigilance are essential for early detection and management.
