What are satellite lesions in leprosy?
Leprosy (Hansen’s Disease) Borderline tuberculoid leprosy is characterized by skin lesions similar to those of tuberculoid leprosy, but they are more numerous and may be accompanied by satellite lesions around large lesions. In borderline leprosy, skin lesions are numerous but remain asymmetrical.
What do leprosy skin lesions look like?
Signs of leprosy are painless ulcers, skin lesions of hypopigmented macules (flat, pale areas of skin), and eye damage (dryness, reduced blinking). Later, large ulcerations, loss of digits, skin nodules, and facial disfigurement may develop. The infection spreads from person to person by nasal secretions or droplets.
What are the three types of leprosy?
The first system recognizes three types of Hansen’s disease: tuberculoid, lepromatous, and borderline. A person’s immune response to the disease determines which of these types of Hansen’s disease they have: In tuberculoid Hansen’s disease, the immune response is good.
How does leprosy cause skin manifestation?
Lepromatous infiltrations can be diffuse, can occur as nodules (called lepromas), or can be plaques. The diffuse type results in the thickened skin appearance of a leonine facies. Neuritic lesions are symmetric and slow to develop.
What is ENL in leprosy?
Erythema nodosum leprosum (ENL), also known as lepra type 2 reaction, is a complication of lepromatous leprosy. It is characterized by the development of inflamed subcutaneous nodules accompanied at times by fever, lymphadenopathy, and arthralgias.
What is Fite Faraco stain?
Fite-Faraco stain is the routinely used method to demonstrate Mycobacterium leprae in tissue sections [3]. Though FF staining is more sensitive than ZN method in detection of Mycobacterium leprae in tissue sections, it is not free from flaws [8,9].
Can leprosy be painful?
Pain is common among patients with leprosy and is multifactorial, but especially associated with nerve damage, leprosy reactions, and neuritis. This is an important consideration, as even after adequate treatment and bacteriological cure, pain may present as a new disabling condition.
What happens if leprosy is left untreated?
Leprosy was once feared as a highly contagious and devastating disease, but now we know it doesn’t spread easily and treatment is very effective. However, if left untreated, the nerve damage can result in crippling of hands and feet, paralysis, and blindness.
What are 3 symptoms of Hansen’s disease?

- Thick, stiff or dry skin.

A case of polyneuritic leprosy is reported. There were minimal changes on skin, but changes in the bones were predominant. It is emphasized that polyneuritic leprosy is an entity. It is also stressed that neuritic leprosy can produce changes in deeper structures like bones, with minimal changes on skin.
What is leprae reaction?
What is a lepra reaction? Lepra reactions are inflammatory reactions occurring in leprosy, due to circulating immune complexes, vasculitis, or T-cell reaction which may be induced by treatment.

Is there a cure for leprosy?
Hansen’s disease (also known as leprosy) is an infection caused by slow-growing bacteria called Mycobacterium leprae. It can affect the nerves, skin, eyes, and lining of the nose (nasal mucosa). With early diagnosis and treatment, the disease can be cured.
