Thanks so much for sharing your experience. I happened to stumble upon this thread today as I was trying to find more information on pityrosporum folliculitis the web. I was diagnosed with mononucleosis in early October, but before I knew I had mono, I had taken penicillin for ten days for what I thought was strep throat. Needless to say, even though my throat got better, within three days I was breaking out in itchy red rashes all over my upper chest. I'm still getting the rashes, though they look a lot more like acne now and they no longer itch when I get them. It was only a week ago (after many doctor and dermatologist visits) that I saw a dermatologist who finally seemed to know what I had and diagnosed me with pityrosporum folliculitis as well.
She prescribed 2% ketoconazole cream to apply twice a day to the spots and also oral 100mg fluconazole to take once every week for one month. This dosage/strength seems extremely low compared to what you've suggested...and I also noticed you said Diflucan (fluconazole) is useless. May I ask why fluconazole is ineffective? It's only been a week so far, but I haven't noticed any changes in my skin despite applying the ketoconazole cream and taking fluconazole. I'm not sure if it's because I haven't given it enough time yet or what. It's at least comforting to know I'm not the only one going through this! I'm so afraid this will become a permanent or untreatable condition. I'm going to try to buy some probiotic supplements and follow your advice on changing my diet to see if that helps. Also do you think adding coconut oil to my diet would help? I read here (http://www.livestrong.com/article/358123-how-does-coconut-oil-kill-candida/) that it's effective in killing Candida yeast. I'm a little confused though, is Candida a different yeast from Pityrosporum/Malassezia? And if so, does treatment differ? I was able to find a lot of information concerning Candida yeasts, like the Candida Diet...yet nothing for Malassezia.
