Have you heard of the word erythrasma?

Customer: replied 1 year ago.
i have heard of it
Expert:  Dr. Pravin replied 1 year ago.

We have seen a few cases that do cause change in the skin color in this uniform pattern resulting in the color change.

They need to be confirmed by Wood's lamp.

Do you have access to Wood's lamp?

Do you have access to ointment called Fucidin?

Customer: replied 1 year ago.
I have no idea what a woods lamp is and no i dont have access to that cream
Expert:  Dr. Pravin replied 1 year ago.

I believe that it is Erythrasma which is a condition called by Corynebacterium and this bacteria releases an acid that causes color change in the area in a very uniform pattern as can be seen.

This cream can be got from the medical pharmacy or can even be got from your family doctor and is the treatment of choice for this condition and should be applied twice a day on the are for 2 weeks.

The Wood's lamp is an instrument that uses ultraviolet light as a diagnostic approach for this condition.

This condition commonly occurs in covered areas like the groin area .

This color change is definitely not a sign of malignancy or anything sinister or any other condition.

The color change reverses back to normal once the bacteria area eliminated from the area.

Please do get back to me in case of any further queries.
