What Causes Rashes On The Upper Body?

Dermatologist 's  Response
Hi,

Perhaps you have pityriasis versicolor which is a superficial fungal infection caused by a yeast, Malassezia furfur.

The yeast feeds on sebum and therefore the patches are usually distributed on torso and chest, areas which are rich in sebaceous glands. The infection is more common in hot and humid weather conditions in summers and presents as reddish brown, dry patches and as hypopigmentation.

I suggest you to use a topical antifungal e.g Ketoconazole 2% cream or lotion. In addition I usually suggest my patients of pityriasis versicolor to take an oral antifungal like either Fluconazole or Itraconazole.

Hope I have answered your query. Let me know if I can assist you further.
