Some of the treatment options are application of creams like Mederma or contractubex gel,
silicone gel dressings,surgery,steroid
injections,compression bandage,cryosurgery,laser therapy and alpha-interferon, 5-fluorouracil and bleomycin.
Regarding the tinea infection,if it is unresponsive to the topical anti fungals,then pls start with oral antifungals.Also if there is no response then the diagnosis needs to be revised.
Hope it helps.
