What causes white spots on leg of an infant?
my daughter is 7 months old
she had no spot on her body when she was born and she got a white spot on her knee at 2 months of age
which we thought could be a birth mark or Nevus depigmentosus
now at seven months i can see two small spots (hypopigmentation ) on her leg again
otherwise she looks healthy and active?
does three spots mean something serious?
can it be tubreous sclerosis?
how to differentiate?
Kindly upload Images
Hello XXXXXXX Thank you for writing to us
I have had one previous discussion with you, sometime back, regarding the same issue..
Light colored spots in children can be due to reasons like...
Post-inflammatory hypopigmentation, nevus depigmentosus, nevus anemicus, pityriasis XXXXXXX vitiligo, tuberous sclerosis etc
Most of these can be differentiated on clinical examination and patient's history.
Tuberous sclerosis usually presents as ash leaf shaped hypopigmented macules, epilepsy and/ or mental retardation in infancy and early childhood.
There may be a family history of tuberous sclerosis Or it could be due to a new mutation.
I request you to upload a few good quality images of these spots so that I am able to guide you better.
Kindly click a digital photograph upload at "Reports section"
Or else you may also mail me the photos at YYYY@YYYY
Kindly mention the subject line of this mail as "Attn Dr. Kakkar".
but last time u told me it looks like nevus depigmentatus
can u tell me the difference between ash leaf shaped and nevus depigmentatus?
also can melgain treat ash leaf spot or nevus spot?
i went to a doctor and he ruled out tuberous sclerosis...i m confused
i ve uploaded the picture of the white mark on my baby knee
pls confirm what type of hypopigmentation it looks like
Likely this is Nevus depigmentosus; not ash leaf macule
This looks like nevus depigmentosus (ND). It has serrated/ irregular margins. ND usually is stable and only grows proportionate to body growth.
Another rare possibility is that this is a vitiligo patch, specially considering that you have noticed a few new spots appearing on legs. Kindly also upload images of these other spots as well.
However, this spot is certainly not an Ash leaf macule.
Ash leaf macules are elongated, ovoid in shape. This shape is classical of tuberous sclerosis.
This is not an ash leaf macule. Your doctor has also ruled out the possibility of tuberous sclerosis.
Tuberous sclerosis is a syndrome. It is also associated with neurological signs like epilepsy Or mental retardation.
These neurological signs must also be considered before making a diagnosis is tuberous sclerosis
Melgain is basic fibroblast growth factor peptide. It is mainly used to re-pigment vitiligo.
It cannot treat ash leaf macule Or nevus depigmentosus but some doctors do try treatments to re-pigment nevus depigmentosus and may notice an improvement.
Some spots I ve put pic twice
Pls revert doctor
I m more worried about ash leaf spots or vitiligo ?
New spots do seem to suggest vitiligo; not ash leaf macules
I have reviewed the Image.
The new Image also shows a single hypopigmented/ depigmented, small sized lesion, probably on her thigh.
This is in addition to the earlier white spot, that was on her knee.
Though, Vitiligo is rare at this young age, however, since she has 2 new white spots come up recently, therefore, i would now like to think more in terms of vitiligo rather than ND.
These are certainly not ash leaf macules of tuberous sclerosis.
It can be really difficult in an infant to differentiate whether a single white lesion is vitiligo Or Nevus Depigmentosus/ ND.
If it was a single stable white spot it would have gone more in favor of ND because ND is usually solitary and stays stable in size.
However, recent appearance of 2 new white spots in her now goes in favor of vitiligo rather than ND.
So u mean to say that it is either vitiligo or nd
But is it sure that it is not ash leaf?? Just want a reassurance
Secondly can it be checked with woods lamp whether it is vitiligo or nd?
Should I use Melgain?
Can vitiligo be treated ?
You may use b-FGF & Fluticasone propionate cream for these patahes
Yes, it is more likely vitiligo considering that new spots have appeared recently.
It is certainly not an ash leaf macule.
The shape of an ash leaf macule is oval at one end and pointed at another end and it resembles a leaf, therefore the name.. ash leaf.
Melgain is basic fibroblast growth factor (b-FGF).
Yes, you may use b-FGF as advised by your doctor. Roll it over the affected area at night, let it dry and expose the affected skin to sunlight the next morning, for a few minutes (10-15 minutes).
I would also like to add a moderately potent topical steroid e.g fluticasone propionate 0.05% cream, once daily. You may use this cream during day time after sun exposure.
Treatment for vitiligo depends on the extent of involvement. Focal vitiligo patches such as these should respond to b-FGF and Fluticasone propionate 0.05% cream.
Response is slow and it may take 6-8 weeks for visible improvement. Therefore you need to be patient with treatment.
Can nd accur more than once in first year of birth ?
Alsi can it be birthmark ?
Vitiligo is likely
I can't comment on why your doctor said that he/she does'nt think it to be a vitiligo... however, the treatment which your doctor gave i.e melgain, is for a vitligo!!
I am sure your doctor must have also kept a possibility of vitiligo.. Is your doctor aware of the appearance of new spots?
As I already said that there may be a diagnostic uncertainty in infants with a single white spot but appearance of 2 new white spots goes in favor of Vitiligo. ND is usually solitary. It does'nt spread.
I suggest you to continue with the treatment and follow up after another 6-8 weeks.
A vitiligo patch would respond to this treatment
Is it differentiate between bs and vitiligo
My doctor told that vitiligo spot look very white in light?
Secondly one spot is not spreading but two new small spots are seen ?
Vitligo would respond to treatment but ND won't
No, ND won't respond to any treatment. Vitiligo will respond to treatment. Therefore response to treatment can sometimes be used as a therapeutic trial in doubtful cases of vitiligo.
As far as the color is concerned Vitiligo is totally devoid of pigment i.e is chalky/ milky white in color whereas ND is hypopigmented rather than depigmented/ totally white but this difference in color is better appreciated in wood's light in a dark room rather than with naked eye.
Vitiligo may remain as a single spot but it will usually spread i.e either increase in size Or new spots may form.
Is there any chance that we missed other two spots as they were very small ?
I still cannot believe it can be vitiligo as there is no heredity issue
I mean the first spot has only grown in size Propionate baby has gained height and weight else I think it has not grown
Secondly does vitiligo spread very fast ?
And if it is indeed vitiligo will it spread for sure if it can stop here ?
Follow up after 6-8 weeks of treatment
I reiterate that ND is usually solitary. If it were a solitary patch I would have still thought in terms of ND as I did in my first discussion.
However appearance of 2 new patches is what makes me think more in terms of vitiligo.
Kindly go through the following link for more details:
White patches only one leg are seen in 'segmental type of vitiligo'.
Vitiligo is not a hereditary disease. In fact most of the affected patients do not have a history in family.
Course of vitiligo is unpredictable.. it may remain stable for years, Or may spread slowly Or very fast.
Treatment depends on the extent on vitiligo and whether it is spreading Or not.
For a few patches such as this only topical treatment is sufficient. If suppose it were to spread in future Oral treatment can be considered.
I think the best approach for you would be to continue with the treatment as advised and follow up after 6-8 weeks of regular treatment.
Is it safe ?
And what can be the side effects ?
b-FGF is generally considered to be safe in children
Yes, Melgain (b-FGF) is considered to be safe.
You can safely use it as advised though there are no controlled studies in children.
Side effects can be some irritation Or redness. You can keep a watch for these side effects. If there is redness Or irritation discontinue it and report it to your doctor.
Also use a topical moderately potent steroid e.g fluticasone propionate 0.05% cream, once daily.
Topical steroids are also first line treatment for a focal vitiligo patch such as this.
