			== Tuberculoid Leprosy ==

			Tuberculoid leprosy is a form of [[leprosy]], a chronic infectious disease caused by the bacterium ''[[Mycobacterium leprae]]''. It is one of the two major clinical forms of leprosy, the other being [[lepromatous leprosy]]. Tuberculoid leprosy is characterized by a strong immune response to the infection, which results in a limited number of skin lesions and nerve involvement.

			=== Clinical Features ===

			Patients with tuberculoid leprosy typically present with a few well-defined, hypopigmented skin lesions. These lesions are often anesthetic due to the involvement of peripheral nerves. The skin lesions are usually dry and hairless, with raised edges. The strong immune response in tuberculoid leprosy leads to the formation of [[granulomas]] in the skin and nerves, which can cause nerve damage and loss of sensation.

			=== Pathophysiology ===

			The pathophysiology of tuberculoid leprosy involves a robust [[cell-mediated immunity]] against ''Mycobacterium leprae''. This immune response is primarily mediated by [[T-helper 1 cells]], which produce [[cytokines]] such as [[interferon-gamma]] that activate [[macrophages]] to kill the bacteria. The granulomatous inflammation is a hallmark of this form of leprosy, and it helps to contain the spread of the bacteria, resulting in fewer lesions compared to lepromatous leprosy.

			=== Diagnosis ===

			Diagnosis of tuberculoid leprosy is based on clinical examination, skin biopsy, and [[skin smear]] tests. The skin biopsy typically shows granulomatous inflammation with few or no bacilli, as the strong immune response limits bacterial proliferation. Skin smears are usually negative for acid-fast bacilli in tuberculoid leprosy.

			=== Treatment ===

			The treatment of tuberculoid leprosy involves [[multidrug therapy]] (MDT) as recommended by the [[World Health Organization]]. The standard regimen includes [[dapsone]] and [[rifampicin]] for a period of 6 to 12 months. Early diagnosis and treatment are crucial to prevent nerve damage and disability.

			=== Prognosis ===

			The prognosis for patients with tuberculoid leprosy is generally good, especially with early diagnosis and appropriate treatment. The strong immune response helps to limit the spread of the disease, and most patients respond well to MDT. However, nerve damage can be permanent if not treated early.

'''Tuberculoid leprosy''' is a form of [[leprosy]] that represents one pole of the spectrum of clinical presentations for the disease. It is characterized by a few well-demarcated, hypo-pigmented and anaesthetic skin lesions, and peripheral nerve thickening. The disease is caused by the bacterium ''[[Mycobacterium leprae]]''.

==Etiology==
Tuberculoid leprosy is caused by ''Mycobacterium leprae'', a slow-growing type of bacteria that causes leprosy. The bacteria multiply very slowly and the incubation period of the disease is about five years. Symptoms can take as long as 20 years to appear.

==Pathophysiology==
In tuberculoid leprosy, the immune response is stronger and there are fewer bacteria present than in other forms of leprosy. The skin lesions are fewer and are characterized by a sharp border and a clear center. The affected skin might be reddened and warm to the touch, and there may be loss of sensation in the affected area.

==Clinical Presentation==
Patients with tuberculoid leprosy may have a single skin lesion or a few scattered skin lesions, which are usually dry, hairless, and have lost sensation due to damage to the underlying nerves. The lesions may be lighter than the person's normal skin color or may be reddened from inflammation.

==Diagnosis==
The diagnosis of tuberculoid leprosy is primarily based on the clinical symptoms. Skin smears taken from the earlobe or from skin lesions can be examined under a microscope for the presence of ''Mycobacterium leprae''.

==Treatment==
The treatment for tuberculoid leprosy is with a combination of antibiotics. The World Health Organization (WHO) recommends a combination of dapsone and rifampicin for six months.

==Epidemiology==
Tuberculoid leprosy is more common in temperate and tropical climates. It is not highly contagious and it is believed that it is transmitted via droplets, from the nose and mouth, during close and frequent contacts with untreated cases.
