A boy aged 8 from Tamil Nadu has a white non-anesthetic, scaly hypopigmented macule on his face (LQ)
|D||Pure neuritic leprosy|
Pityriasis alba is typically found on the face, particularly the cheeks and chin, of children. Patches of oval macular skin lesions with fine adherent scales are seen.
These patches are the sites of a mild eczematous process, resulting in poor melanin transfer to keratinocytes, as well as desquamation of the previously tanned skin. The lesions are virtually painless. They usually disappear spontaneously.
The treatment of choice is a mild topical steroid such as 1 % hydrocortisone cream'.
