Answer 9

In tuberculoid leprosy

a. peripheral nerves are involved symmetrically
True b. the lepromin test is positive
c. hair growth is normal in affected skin lesions
d. smear negative cases can be treated with steroids alone
True e. skin lesions usually have a well-demarcated, raised edge


Peripheral nerves may be thickened but are characteristically involved asymmetrically.

There are typically only 1 or 2 skin lesions which are well-demarcated, dry, scaly, hypopigmented, anaesthetic and hairless.

Treatment of tuberculoid leprosy should include daily dapsone and supervised monthly rifampicin for six months.
