Histoid Leprosy

Histoid leprosy is a rare and chronic bacterial infection caused by Mycobacterium leprae. It primarily affects the skin and nerves, leading to various symptoms. Let’s break down this complex topic into simple language for better understanding.

Histoid leprosy is a rare form of leprosy caused by a bacterium called Mycobacterium leprae. This bacterium mainly affects the skin and nerves, causing distinctive symptoms.

Types of Histoid Leprosy

There are two primary types of leprosy: paucibacillary and multibacillary.

1. Paucibacillary Leprosy:
   • This type involves a few bacteria in the body.
   • Characterized by one or a few skin lesions with a lighter pigmentation.
   • Typically, nerve damage is less severe.
2. Multibacillary Leprosy:
   • Involves a larger number of bacteria.
   • Presents with multiple skin lesions and a darker pigmentation.
   • Nerve damage can be more extensive.

Causes of Histoid Leprosy

9. MRI Scan: Detects nerve involvement.
10. Electroneuromyography: Measures nerve function.
11. X-rays: Assessing bone involvement.
12. Ultrasound: Imaging to detect nodules or swelling.
13. CT Scan: Detailed imaging of affected areas.
14. Immunofluorescence: Detecting antibodies or antigens.
15. Fine Needle Aspiration: Extracting cells for examination.
16. ELISA Test: Detects antibodies in the blood.
17. Western Blot: Identifying specific proteins in blood.
18. Genetic Testing: Assessing susceptibility.
19. Physical Examination: Assessing overall symptoms.
20. Eye Examination: Checking for ocular involvement.

Treatments for Histoid Leprosy
