Hello,

Thanks for your query.

I would like to answer your question to the best of my knowledge.

You have mentioned about two things:
1) Red spots on the chest and stomach
2) Pityriasis versicolor on your arms

Firstly, coming to the red patches, possibilities in this case may be Pityriasis rosea (like you mention), syphilis and ringworm of the skin or psoriasis.

P.rosea frequently starts with a single patch and then progress to multiple oval red patches mostly on the chest, back, abdomen and arms. It resolves in 6-8 weeks usually. Topical steroids and calamine lotion are prescribed to treat it.

Ringworm is fungal infection looking like reddish round patches with clearing in the centre. Treated with anti fungal creams application like Clotrimazole 1% twice daily for 2-3 weeks or oral anti-fungals in severe cases.

Syphilis is a sexually transmitted, rare condition.
Psoriasis can present as Guttate psoriasis, where multiple, small, red, and scaly, patches appear on the arms, legs and the body.

I can help you better if you can upload picture of the above (in good resolution).

Also do mention your age and gender and let me know if your rashes appeared acutely, meaning if it came up suddenly now or grew gradually one by one.

You can upload them with the query or send them to

Hepatitis C is unlikely with this presentation only.

Secondly, for the P. versicolor in your arms, you can apply Ketoconazole 2% cream once daily on affected areas for 3 weeks. Some cases also require oral prescription anti-fungal medicines which can be prescribed by your dermatologist.

I will be happy to assist you with queries further.

Wish you good health!

Hi,

Thanks for following up.

I have gone through the picture sent. Although picture is not very clear I don't think it is a ringworm. P.rosea is most likely possibility. However a close examination by a dermatologist can rule out Syphilis and Guttate psoriasis.

It is important you visit a dermatologist and get the appropriate treatment started. In most cases, your doctor can identify pityriasis rosea simply by looking at the rash. Treatment of P.rosea consists of appropriate topical corticosteroid, antihistaminic tablets and calamine lotion. Recurrences may occur and it is important to follow-up.Clinical examination is usually sufficient to identify guttate psoriasis.
Blood tests may be required to rule out secondary syphilis.

Hope I have solved your query. I will be happy to provide further help if needed.If you do not have any clarifications, you can close the discussion and rate the answer.

Take care and good luck.
