Skin, Hair & Nails

Hi doc, I'm posting this question on behalf of my 56 years old mother who has been experiencing persistent rashes on both her arms since Jul 2017. We have monitored the rashes over a period of time, and they do not seem to be caused by any specific allergens/temperature changes. These rashes appear to be scaly at times, but they do not hurt or itch.

Her GP diagnosed her with Acute Eczema as she has no previous history of skin related complaints. He gave her some creams which helped for 2-3 days. However, they resurfaced about a week after discontinuation of the cream.

The rashes will come on and off for no apparent reason and they appear in a large singular patch. I am a little concerned that this could be a potential problem besides eczema for her. Would greatly appreciate it if you can advise on whether there are any other causes for such a rash (pic attached) and if it is necessary for her to see a specialist. Thanks in advance!

DOCTOR’S ANSWER (1)

Dear JN,

Thank you for the question. The photo of the rash can go for eczema.
 
The rash in eczema is usually itchy, and aggravated by scratching. Persistent scratching or reaction to certain creams applied can cause the rash to be recurrent or persistent, so your mother should refrain from scratching as far as possible.
 

If the rash is still persistent despite treatment, you may want to consider seeing  your doctor/dermatologist to rule out an underlying cause for the persistence, such as a fungal infection or allergic contact dermatitis.

Further tests and adjustments to her treatment regimen may be necessary.
