Summary
This study describes Lichen Planus patterns in 95 Nigerians over 3 years. The disease predominantly affects younger females, with widespread lesions and seasonal variations, particularly during the rainy season.
Area of Science:
- Dermatology
- Epidemiology
Background:
- Lichen Planus is a common inflammatory condition.
- Understanding its presentation in diverse populations is crucial.
Purpose of the Study:
- To describe the epidemiological and clinical patterns of Lichen Planus in Nigerians.
- To identify potential etiological factors in tropical Africa.
Main Methods:
- Retrospective analysis of 95 Nigerian patients diagnosed with Lichen Planus over a 3-year period.
- Data collection on patient demographics, lesion distribution, clinical variants, and seasonal variations.
Main Results:
- Lichen Planus constituted 5% of all skin cases.
- Younger individuals, particularly females, were predominantly affected.
- Widespread lesions (68%) were common, with frequent large papules, scaly patches, and hypertrophic verrucous lesions on the legs.
- Oral lesions were infrequent.
- A peak incidence was observed during the rainy season (April-September, 65%).
- Pruritus was a constant symptom, and lesions healed with significant hyperpigmentation.
- No cases of subtropical (actinic) Lichen Planus were reported.
Conclusions:
- Lichen Planus in Nigeria presents with distinct epidemiological and clinical features.
- Seasonal variations and specific lesion types are notable.
- Potential contributing factors in tropical Africa include drugs, weather, and the use of native sponges.
