Summary
This study reports a rare case of coexisting leprosy and psoriasis, challenging the long-held hypothesis that these two distinct skin diseases rarely occur in the same individual.
Area of Science:
- Dermatology
- Infectious Diseases
- Immunology
Background:
- Leprosy and psoriasis are distinct skin conditions with different clinical presentations and etiologies.
- Historically, psoriasis was sometimes misclassified as a form of leprosy.
- Previous observations suggested a low incidence of co-occurrence between leprosy and psoriasis.
