Leprosy Dermatopathology

Leprosy, also known as Hansen's disease, primarily affects the skin and nerves. In dermatopathology, it is characterized by specific skin lesions caused by the bacterium Mycobacterium leprae. Under a microscope, affected skin shows a mix of inflammatory cells, including lymphocytes and macrophages, alongside nerve damage. These changes lead to symptoms like skin patches and numbness. Early diagnosis and treatment are crucial to prevent further complications, as the disease can harm facial features and limbs due to nerve involvement. Understanding these patterns helps pathologists confirm leprosy and guide appropriate treatment.
