This study analyzed 518 skin cancer cases over 20 years, finding spinocellular carcinoma most common in Black Africans, often linked to chronic ulcers. Malignant melanoma also showed unique patterns in Black subjects.

Area of Science:

  • Dermatology
  • Pathology
  • Epidemiology

Background:

  • Skin cancer is a significant health concern globally.
  • Understanding the epidemiological features of skin cancer is crucial for public health.
  • Previous studies have highlighted variations in skin cancer incidence across different ethnicities and geographic regions.

Purpose of the Study:

  • To determine the epidemiological characteristics of skin cancer diagnosed in Lome Teaching Hospital over a 20-year period.
  • To identify the most prevalent types of skin cancer in the Black African population.
  • To investigate the specific patterns of malignant melanoma in Black subjects.

Main Methods:

  • Retrospective study design.
  • Analysis of 518 skin cancer cases diagnosed between [start year] and [end year] at Lome Teaching Hospital.

  • Categorization of skin cancers including carcinoma, malignant melanoma, Kaposi's sarcoma, and skin sarcoma.

    • Main Results:

    • Carcinomas represented 56.6% of cases (288/518), with spinocellular carcinoma being the most frequent (254 cases).
    • Spinocellular carcinoma frequently developed on chronic phagedenic ulcers (143 cases).
    • Malignant melanoma (12.3%), Kaposi's sarcoma (13.9%), and skin sarcoma (18.3%) were also significant findings, with particular patterns noted in Black subjects.

    Conclusions:

    • Spinocellular carcinoma is the predominant skin cancer in Black Africans, often associated with chronic ulcers.
    • The study confirms the distinct epidemiological profile of malignant melanoma in Black individuals.
    • These findings underscore the need for targeted prevention and treatment strategies for skin cancer in this population.
