Background: Malignant melanoma is an aggressive skin cancer with a high risk of
metastasis and mortality, particularly when diagnosed late. Although less
common in people with darker skin, melanoma in sub-Saharan Africa is often
characterized by delayed presentation contributing to poor outcomes.
Aim:
This study aimed to describe the demographic characteristics, anatomic
distribution, and temporal trends of malignant melanoma presentations in a
tertiary hospital.
Methods: A retrospective review was conducted for 26 patients diagnosed with
malignant melanoma between 2014 and 2023. Data on age, sex, anatomic site, and
year of diagnosis were extracted from medical records. Statistical analysis was
performed using SPSS version 23. Results were summarized using frequencies and
percentages.
Results: A total of 26 patients with malignant melanoma were reviewed. Most
patients were aged 55–69 years (42.3%), followed by those aged 40–54 years
(34.6%). Only one patient (3.8%) was aged 25–39 years, while patients aged 70
years and above accounted for 19.2% of cases. Females slightly predominated,
with 14 cases (53.8%), compared with 12 males (46.2%). Yearly distribution
showed variability, with peak presentations in 2021 and 2022, each contributing
five cases (19.2%). The lowest numbers were recorded in 2018, 2019, and 2023,
with one case (3.8%) each. The most common anatomic site was the foot,
accounting for 18 cases (69.2%). Other sites were less frequently affected,
including the groin, scalp, and thigh (7.7% each), while the mons pubis and
palm accounted for 3.8% each.
Conclusion: Malignant melanoma in this study predominantly affected middle-aged and older adults, showed a slight female predominance, and most commonly involved acral sites, particularly the foot. The observed temporal variability underscores the need for improved early detection and surveillance.
