My wife has got white marks on the back. On seeing doctor, doctor diagonised as skin fungus. He advised to apply Ketovate Solution ( Ketoconazole solution) one hour before taking bath. In night , Kansel - ds lotion to be applied. This treatment is going on for last 2 months but there is no improvement. We have observed that it starts in summer and continues for 2 months. This gets cured within 2 months. But, this time it is not getting cured. Please suggest what to do as my wife is very much worried.
From the description it more likely seems to be Satyriasis tricolor infection causing hypopigmented lesion without itching. It usually increased in the sweat causing months (summer). The local applications given by doctor are God but considering the resistance this time you need to change the medication. And she should also have one oral antifungal shot such as Fluconazole 400 mg single dose, which is more ideal treatment of the condition. So my opinion is that give her single tablet of fluconazole 400 mg single dose and ask her to apply fluconazole or itraconazole cream twice a day & see the results. It may take 20 -30 days to resolve this type of infection. Once cured precautions should be taken so that they won't secure. For that it is advisable to have proper dermatological consultation.
