Brief Answer:
Hansen's disease (
Leprosy)
Detailed Answer:
Hi,
Welcome to health care magic.
I have gone through your query, I understand your concern regarding the pale patches on your finger.
Let me explain few details about leprosy so that I can relieve your
anxiety.
Leprosy is a disease now confined to developing countries and is still found in India, South east Asia and Brazil.
It is an infection caused by a bacteria called
Mycobacterium leprae which is spread mainly by contact with infected person.
This disease involves the skin, peripheral nerves and nasal mucosa.
There are at least four types of leprosy - lepromatous, tuberculoid, borderline and indeterminate types.
Numb patches of skin is seen in Tuberculoid type of leprosy.
These patches are clearly defined patches and no sensation(
anesthesia) is felt only in those areas of skin.
Simple bed side test can be done to confirm the anesthesia. It is called the pin test where a blunt pin can be used to touch the
anesthetic patch with patients eyes closed and patient is asked if he/she is feeling any sensation.
But this test is subjective.
Leprosy can be confirmed by a slit skin smear of the anesthetic patch for acid fast bacilli (Leprae bacilli)
In your case, I am suspecting neuropathy rather than leprosy as you mention
numbness of the whole finger where as in leprosy very clearly demarcated areas of numbness is seen.
Nodules on the nose need to be examined to rule out the cause. Such nodules may be seen in spectacle users where nodules develop on the bridge of the nose.
I hope I have cleared your doubts.
Please get back if any more clarifications.
Thanks.
