Leprosy

Question
20 out of 28
 

A 45-year-old male had multiple hypo anesthetic mildly erythematous large plaques with elevated margins on trunk and extremities. His ulnar and lateral popliteal nerves on both sides were enlarged. The most probable diagnosis is:



A Lepromatous leprosy

B Borderline leprosy

C Borderline tuberculoid leprosy

D Borderline lepromatous leprosy

Ans. C
Borderline tuberculoid leprosy

The early lesion of tuberculoid leprosy is often a hypopigmented macule that is sharply demarcated and hypesthetic. Slowly the lesions enlarge by peripheral spread, and the margins become elevated and circinate or gyrate. Then the central area becomes atrophic and depressed. Fully developed lesions are densely anesthetic and have lost the normal skin organs (sweat glands and hair follicles). Although any peripheral nerve may be enlarged, most commonly affected are ulnar, posterior auricular, peroneal and post-tibial.
