What Causes Painful Pus Filled Red Sores On The Scalp?
Please see as follows
Detailed Answer:
Hello,
I understand your concern.
Although I would need more information as to how long has this been going on, whether it is itchy or not, just by the description and excluding a parasitic or fungal infection. Given the failure of treatment with ketoconazole and triamcinolone, I am inclined to think it is eczema.
If you haven't tried it yet, I'd suggest you give Zinc Pyrithione and Salicylic acid a try. This will usually help get rid of the scales and flakes. Also rubbing virgin olive oil on the scalp and leave it overnight may bring considerable relief.
However, the biopsy is the gold standard in this case and it will give the definitive answer as to the real underlying cause. So without the results, there is little we can do to figure the correct diagnosis.
I hope this helps.
Wishing you good health and all the best.
Yes, it could.
Detailed Answer:
Yes, it may be basal cell carcinoma or squamous cell cancer. However, doctors prefer to err on the cautious side when it comes to confirming and delivering such diagnosis. Other diagnosis need to meticulously be taken in consideration and ruled out.
The duration and persistence of the lesion and the scales that don't go away, or return after being scraped off point to a diagnosis of cancer.
Ultimately, the biopsy results hold the definitive answer.
I hope this answers your question but if you have further questions questions I'd be happy to answer them.
Wishing you good luck and all the best.
