What are the classification of leprosy?

Leprosy has traditionally been classified into two major types, tuberculoid and lepromatous. Patients with tuberculoid leprosy have limited disease and relatively few bacteria in the skin and nerves, while lepromatous patients have widespread disease and large numbers of bacteria.

Which of the following type of leprosy is not included in Ridley Jopling classification Mcq?

This classification classifies leprosy into five types—(1) TT (tuberculoid), (2) BT (borderline tuberculoid), (3) BB (borderline-borderline), (4) BL (borderline lepromatous), (5) LL (lepromatous). * Note: Ridley-Jopling classification does not include the indeterminate and the pure neural types of Hansen’s disease.

What is Polar lepromatous leprosy?

Lepromatous leprosy is characterized by multiple skin lesions that are smaller than those observed in tuberculoid leprosy (Fig. 334-3). Although the sites of skin lesions are similar to those of tuberculoid leprosy, the multiple lesions of lepromatous leprosy are often symmetrically distributed.

What is Paucibacillary?

Paucibacillary patients are those who are skin smear negative and show no evidence of more advanced disease on biopsy. Multibacillary patients are those who are skin smear positive and/or have a biopsy indicating more advanced disease.

What are the three types of leprosy?

The first system recognizes three types of leprosy: tuberculoid, lepromatous, and borderline. A person’s immune response to the disease determines which of these types of leprosy they have: In tuberculoid leprosy, the immune response is good.

Who Paucibacillary leprosy classification?

Classification (clinical): Paucibacillary single lesion leprosy: 1 skin lesion. Paucibacillary leprosy: 2 to 5 patches or lesions on the skin. Multibacillary leprosy: >5 patches or lesions on the skin.

What is the differential diagnosis for leprosy?

Among the cutaneous infectious granulomas that may be considered in the differential diagnosis of leprosy are tuberculosis (lupus vulgaris, tuberculosis verrucosa cutis, erythema induratum of Bazin), “lepromatoid” atypical mycobacterial infection (e.g., mycobacterium chelonae), leishmaniasis skin infections (lupoid.

What does a positive Lepromin test mean?

Understanding the test results Redness, swelling, or other skin changes indicate the presence of tuberculoid and borderline tuberculoid leprosy. If you’ve tested positive for leprosy during a biopsy but don’t have a skin reaction, you may have lepromatous leprosy.

What are the 3 types of leprosy?

What causes leper?

Leprosy is caused by a slow-growing type of bacteria called Mycobacterium leprae (M. leprae). Leprosy is also known as Hansen’s disease, after the scientist who discovered M. leprae in 1873.

What is the Ridley-Jopling model of leprosy?

Ridley-Jopling: Depending on the host response to the organism, leprosy can manifest clinically along a spectrum bounded by the tuberculoid and lepromatous forms of the disease. Most patients fall into the intermediate classifications, which include borderline tuberculoid leprosy, midborderline leprosy, and borderline lepromatous leprosy.

What are the different types of leprosy classification?

Leprosy Classification-Madrid and Ridley and Jopling Classification 1 Tuberculiod 2 Boderline Tuberculiod 3 Boderline borderline 4 Boderline Lepromatous 5 Lepromatous More

What is the Ridley-Jopling system?

The Ridley-Jopling system is used globally and forms the basis of clinical studies of leprosy. It may also be more useful in guiding treatment regimens and assessing risk of acute complications. Physical findings in each subtype are presented in the Clinical section.

How is multibacillary leprosy diagnosed?

Multibacillary leprosy includes LL, BL and BB forms and paucibacillary leprosy includes the TT and BT forms of the Ridley-Jopling classification system. – Laboratory diagnosis is based on the detection of acid-fast bacilli in a Ziehl-Neelsen stained nasal smear and skin-split smear taken from the ear lobe or from a skin lesion.
