The cause is because of the presence of a yeast (fungus) called malassezia furfur.
Clinically is causes hypopigmented patches with fine scales on the surface on scratching (scratch sign)
Microscopy examination of the scales provides a definitive diagnosis with an appearance of spores and hyphae called “spaghetti and meatballs.”
Treatment is easy and consists of applying antifungal creams like azole group (eg clotrimazole/Ketoconazole/Sertoconazole).
However the condition tends to recur and a weekly prevention with selenium sulphide shampoo can help.
