Hello doctor,

Two weeks ago, I noticed a small red circle on my back. I figured it could be a rash due to me using a bar of new laundry soap. However, within a few days, I noticed the same red spot on the upper part of my stomach (below my chest). When I looked to the rash in my back, it had doubled in size. Presenting a red or pink circle and was itchy. I immediately assumed it was ringworm and began to apply Lotrimin two times daily. However, within a week, the rash has now spread to my stomach area and onto my breasts. The itching has gone, but I am wondering if it could be a ringworm or pityriasis rosea?

Hello,

Welcome to icliniq.com.

Yes, these are typical lesions of pityriasis rosea (attachment removed to protect identity). Annular plaques with scaly edges and free at the center. These are not ringworm infection because the center of lesions are filled, whereas, in ringworm, the center is bright. Kindly follow the prescription,

1. Tablet Erythromycin 500 mg four times a day.

2. Apply steroid lotion (like Hivate) plus Calamine lotion (mix both of them and apply bd).

3. Take antihistamine tablet once a day.

Maintain hygiene of area, wash with soap and water.


Probable diagnosis:

Pityriasis rosea.
