Which image shows pityriasis versicolor?
Answers:
A= Vitiligo
This milky white lesion is completely depigmented centrally which is typical of vitiligo.
Careful examination will show mild hypopigmentation as well as fine scale. The cheeks are a typical site for pityriasis alba.
In the active phase, pityriasis versicolor is light brown and scaly. Because the causative yeast releases azelaic acid, it causes temporary hypopigmentation as the active infection resolves.
D= Extragenital lichen sclerosus
Lichen sclerosus produces mild atrophy and sclerosis as well as depigmentation - it is usually present on the genitalia even when there is extragenital disease.

Thank you for raising awareness about this issue. Such diseases are common in our country, and recovery often takes a long time. Unfortunately, many patients discontinue their treatment midway, which can affect their recovery.
