Suggest Treatment For Bump On Lower Back And Thighs

default
Posted on Mon, 13 Oct 2014
Question: Hello,

I noticed some red like bump on my lower back and inner thighs last week, over the weekend had a cold, congested nose, and cough. Saw a doc for cold on Monday, by Wednesday my bumps had spread a lot more on my lower back, both inner thighs and above some flat crust like scab and dark on the inside after they flattened I guess. Noticed some on my upper arm by arm pit, both of my top feet now have little bumps but they aren't red like my thighs and back. None of them itch, they keep spreading on my lower back and inner thighs. Doc says it might be Pityriasis on back and thighs, eczema on feet. Need a second opinion? Thank you.

Brief Answer:
Clinical assessmen and biopsy needed

Detailed Answer:
Hello,
Thanks for posting your query on HealthcareMagic.

The lesion on your thigh appears to be an erythematous lesion covered with silvery scales.
The history of spreading non-itchy lesion raises the possibility of psoriasis in my mind.
Psoriasis is a non-itchy scaly erythematoses which is common on extensor surface of the body like elbows, thighs, back and even on scalp and genitalia.
However, this is just one of many other possibilities.
Pityriasis is also a scaly erythematosus characterized by scaling of the skin.
However, a biopsy is required to make exact diagnosis.
You need to consult a dermatologist for clinical assessment and biopsy.
The lesions on the feet has not been uploaded so I cannot comment on the lesion on feet.

If you have more queries, I will be glad to answer.

Thank you for the response. Now if that is in Psoriasis instead of Pityriasis, what can I expect in the week to two, will it spread more or how long before it will start to go away and will it come back? Although they don't itch, they do sting at times.

So far based on the Doc I saw theory of Pityriasis, she told me it will keep spreading more before it get better, but should start noticing it going away in 3-4 weeks but last up to 6 months. And from Wednesday till now it has spread a lot more. Someone else had mentioned scabies, is that possible? Granted I'm in the Middle East under extreme hot weather, stressful environment at time, also recently traveled to Central XXXXXXX a lot of signs pointing in different direction. I have a follow up at the clinic on October 1, I just hope it won't be too late.
