Detailed Answer:
Hello XXXXXXX

Welcome and thanks for posting your query to the forum.

I can understand your concern for peculiar skin formation over the left parietal region of your uncle's scalp. As per the appearance I keep a possibility of sebaceous nevus (also known as sebaceous nevus of Jadassohn) rather than melanoma. In view to diagnose the same and help you best I humbly request you to kindly provide certain important points so the I can guide you best:

-Since exactly how long he has this condition.

- Is there any itching over the same.

- Are you over weight or what is your height and weight.

- Had he taken any treatment for the same.

Hope to hear soon from your side.

With regards,

Dear XXXXXXX

Welcome back to the forum and thanks for your follow up with details.

As per the clinical appearance of the lesions it appears to be Sebaceous nevus. But the point against it is the time period. In sebaceous nevus the area is present since birth or childhood. In your uncle's case it is present since 10 years which goes against the same.

In such situations in my patients the basic approach is to go for skin biopsy. I generally take a small piece of 3 millimeter from the affected skin. This skin is examined for the best possible cause an then the findings are clinically correlated.

I suggest you to meet a dermatologist and go for skin biopsy to get the exact diagnosis of the condition.

My best wishes for the earliest recovery.

With regards,
