Leprosy simulating lichenoid eruption: case report and literature review

Area of Science:

• Dermatology
• Infectious Diseases
• Immunology

Background:

• Leprosy, a chronic infectious disease, typically presents with diverse skin lesions like macules, papules, plaques, nodules, or diffused infiltration.
• The clinical presentation of leprosy can vary significantly based on the host's immune response, often deviating from classical patterns.
• Diagnostic confusion arises due to the wide spectrum of leprosy manifestations, necessitating a high index of suspicion.

Observation:

• This article describes a rare case of leprosy that mimicked a lichenoid eruption.
• The patient's presentation deviated from typical leprosy manifestations, posing a diagnostic challenge.
• The case underscores the importance of considering leprosy in differential diagnoses for unusual skin conditions.

Findings:

• Leprosy can present with atypical skin lesions, simulating other dermatological conditions such as lichenoid eruptions.
• Accurate diagnosis requires a comprehensive evaluation, including clinical presentation, immunological status, and potentially histopathological examination.
• The study emphasizes the variability in leprosy's clinical spectrum.

Implications:

• Clinicians should consider leprosy in the differential diagnosis of lichenoid eruptions, especially in endemic areas.
• Recognizing rare presentations of leprosy is vital for timely and effective treatment, preventing disease progression and complications.
• This case contributes to understanding the diverse clinical spectrum of leprosy and aids in refining diagnostic approaches.
