More like a patch of Seborrheic dermatitis,and should respond to hydrocortisone creme, applied just for a couple of days, surely a doc should be able to guide you.
it looks almost circular, did you put something on, or is it reacting to something. its best to see your doctor, i dont know how healthcare works in japan.
Yes, I thought that seborrhoeic dermatitis might be responsible too. That said, whenever I've had patches of seborrhoeic dermatitis in the past they have always responded to topical antifungals almost immediately. Perhaps I ought to buy a combined corticosteroid and antifungal cream to see if that helps.
I'm very sure that a doctor would be able guide me, however none of the local doctors speak English and it's such a simple thing that I doubt it's worth the hassle and expense of travelling to an urban centre. If it continues to recur after I've tried this, then I guess I'll go to some effort to seek some medical help. I had an aunt who suffered from a basal cell carcinoma on her face and she was left with a nasty scar after they removed it. To my knowledge, however, BCCs no not wax and wane.
A single scaly patch does need evaluation to rule out Bowen's, but do not see a basal cell ca with this presentation..And surely wax and wane is not like it.The response to a combination should rule out Bowen's too.Do consult your doc.
You've been most helpful - thank you very much. I will proceed as discussed.
you should also have your bloodwork check for hodgkins as well.
