Why is there soreness and non-healing scab in my arm?

Question

Hello doctor,

I have soreness on arm and scabs but when the scab falls off, it does not heal. An original sore was small rounded with a crust. Sore is over a year old. I am using aloe vera cream and steroid cream for a month.

Answer 1

Hi,

I am glad you chose icliniq for your medical-related queries.

I understand your concern and will try to help you with it.

I have viewed the images (attachment removed to protect patient identity). I can see a crusted plaque. This could be either in situ carcinoma (Bowen's disease) or a squamous cell carcinoma. I can see signs of photodamage in the background, lots of sunspots. I suggest a skin biopsy. Do you have any symptoms like pain or itching?

Thank you for consulting me.

Answer 2

Hi,

Welcome back to icliniq.com.

I read and understand your concern.

My first possibility would be either a squamous cell carcinoma or Bowen's disease since this is a sun-exposed site. Melanoma is a less likely possibility. It is usually dark or pigmented whereas this is a red, crusted patch.

Looking forward to your response in order to help you.

Thank you.
