What are CBC and PBS results in pityriasis rosea?

Question

Hello doctor,

I recently had my blood tested, and it turned out that I have a WBC of 16000. I have no fever, a cold, or a cough. Although I have rashes, I suspect this is pityriasis rosea.

My doctor is not aware of my suspicion. Now he wanted me to undergo a CBC and a peripheral blood smear. If I really have pityriasis rosea, what would probably be the result of my CBC and PBS? I am 22, female, 5'1", 105 lbs.

Please advise.

Hello,

Welcome to icliniq.com.

I understand your concern.

Pityriasis rosea is a form of viral skin infection. Your total WBC count can be high because of that, and in your CBC, high lymphocytes can be a possibility, but it is not the rule. For your rash, Levocetirizine 5 mg OD, like an oral antihistaminic drug, can be prescribed.

If needed, a topical steroid can also be prescribed. I suggest you consult a dermatologist for examination. Repeat your CBC with peripheral smear examination report after a week.

I hope this helps you.

Thank you.
