In cases of Sweet Syndrome there will be elevated levels of WBCs on the blood test. The skin biopsy will show abnormalities which are characteristic of Sweet Syndrome. These two tests will confirm the diagnosis of Sweet Syndrome.
How is Sweet Syndrome Treated?
Minor cases of Sweet Syndrome do not require any treatment and the rashes go away by themselves within a few days. For severe cases of Sweet Syndrome, steroids in tapering doses like prednisone are extremely beneficial in getting rid of the rashes formed as a result of Sweet Syndrome.
The medication is given in tapering doses as long term use can lead to certain undesirable side effects. Additionally, certain creams or lotions can also be applied on the lesions to facilitate faster healing of the lesions. In case if there are only a few lesions then an injection of steroids can be injected directly on the lesions so as to treat Sweet Syndrome.
In cases where an individual is intolerant of steroid use, then other forms of medications are used to treat Sweet Syndrome. These medications are potassium iodide and colchicines, which have shown to be quite effective in treating the lesions caused by Sweet Syndrome.
