intradermal melanocytic nevus?


this is the result of a pathology I need to know what it means
----------

It means that you have melanocytes in the dermal layer of the skin. Nevus means that it is a mole. THIS IS NOT CANCER.

Basically there are a few types of moles. A compound nevus refers to a mole in both the epidermis and dermis. An intradermal nevus means that it does not extend up into the epidermis.

Melanocytic means that the nevus is made up of melanocytes. These are the cells that give moles color and give darker skinned persons their color. Since it does not say "melanoma" it is not considered to be malignant.  (+ info)

What is the different between intradermal and intramuscular?


What is the different between intradermal and intramuscular?
----------

intradermal is just under the skin....like a TB skin test
Intramuscular is into the muscle, like the arm or buttock  (+ info)

How to remove nevus with a simple way by myself at home?


How to remove the nevus on my nose? Don't tell me go to do surgery or use laser...I want ways that I can do at home by myself. Somebody suggests me to lightly rub the nevus with fresh lemon juice by using a Q-tip. I've tried that, it seems to work a very very very little bit but please give me a better way because it hurts my nose and takes a long time and I'm still suspecting whether it works or not.
----------

Sorry, you need to see a dermatologist for nevus removal in office.  (+ info)

What is a intradermal dose and a intramuscular dose? Whats the difference?


The travel clinic Im going to is charging less then £20 for each rabies jab. I asked why so cheap as everywhere else I looked was double and she said :

we do an intradermal dose that uses less of the vaccine allowing us to charge less. This method still gives you the same protection as using more of the vaccine for an intramuscular dose.
----------

Intramuscular means injected into the muscle. Intradermal means injected into the dermis.  (+ info)

What is the difference between an Intradermal and a Scratch test?


Can't seem to find what is different about these two allergy tests, can anyone help clarify?
----------

Scratch test is where they literally just scratch your skin with this metal little thing where at the end it's sharp. They put a dot of liquid which contains allergens, such as pollen, grass, dust, etc.

Intradermal is where they actually inject the allergens into your skin, (under your skin) it's actually more accurate than the scratch test.  (+ info)

Why would doctors excise an atipical nevus?


I had a mole removed (shaved) and it came back as an atypical nevus, I am going to go back to have the rest taken out, but if it's not cancer why do they need to take the rest out?
----------

Because of the word "atypical". An atypical nevus has the possibility of degenerating into a melanoma, as opposed to a regular nevus. So, to be on the safe side, it's better to get rid of a potentially serious condition, easily, than to wait until (if ever) it does turn into a malignancy that can cause death. And, of course, there is the legal side of this too: should it turn into a melanoma, and the doctor had not taken it off, then he'd probably be looking at a law suit for not having acted sooner and preventing a death.  (+ info)

What if you tested positive for Intradermal Tuberculin Test, but swelling appeared after 72 hours?


will it still be considered positive or already considered false negative?
----------

I would consider it a negative if it didn't react within 72 hours. If you're concerned, have a re-test done on the other arm in a month or two.

How bad was the swelling?

Alternatively, call your doctor.

Edit: I'm a nurse and have never heard of the TB test killing anyone because of a previous positive response. I would be concerned about the credentials of a medical provider telling me this.
There have been documented cases of severe anaphylactic reaction (ALLERGIC reaction) to the Mantoux test, many of which were in people without a prior history of positive tests. This was linked more to the serum used to administer the test, and the patients having an allergic reaction to the serum itself -- not to the protein included in the serum that triggers a positive response in TB-positive patients.
A positive PPD/Mantoux result should not get worse with each administration and certainly should not kill you. I have known people from Eastern European countries where the TB vaccine is administered, who showed up positive on the TB test every year they were required to receive it, and they are still quite alive.

Edit 2: Do not listen to the person above. (See, how does it feel? You should be nicer when giving advice.)

Page 4.4.1 of the manual linked above states:

"Ask [patients] if they have had a previous severe reaction to the tuberculin antigen. Exclude only those who report a previous severe allergic reaction involving the whole body and/or ulceration at the site of a previous TB skin test from the TB component."

You (the question asker) do not fit this criteria.
It is safe for you to get re-tested.

Edit 3:
Really, people. MILD SWELLING more than 72 hours after administration is very unlikely to be an allergic or anaphylactic reaction.

Question asker:
Go back to your doctor, and ask them if they think you should be re-tested.

Let a qualified professional make that decision, don't listen to ANY of us here on Y!A. Not even me, if that's what it takes to get you to just ask your doctor. ;-)  (+ info)

Does anyone know anything about sebaceous nevus?


I have read that sebaceous nevus can be linked with neurological disorders. Would a child be born with these disorders, or could the child develop normally as an infant, then the disorder develop later?
----------

Nevus sebaceus is usually noted as a solitary lesion at birth or in early childhood, whereas the characteristic features may not develop until puberty.

Here's an article on the condition:

any other babies have a Linear Sebaceous Nevus?


My 12 week old son has just been diagnosed with a Linear Sebaceous Nevus, i was hoping for any advice or stories from parents who have experienced this with their children?
In common terms, Nevus means a birthmark or mole. They are generally benign but few have malignant (cancerous) potential. It depends on type, location, size and other morphological features of the mole.
Sebaceous nevus is a very rare type of epidermal nevus disease. It may be associated with other birth abnormalities.

sorry really dont mean to be rude..im just wondering what linear sebaceous nevus is? ive never heard of it...  (+ info)
