Brown Spots on Hands Appeared Overnight

[30Healthy]

I am a very healthy 30 year old woman. 2 days ago, I noticed approx. 20 small brown spots appeared on the back of my right hand. One day the skin in that area was smooth and even toned, the next day...spots! They are located between my thumb and index finger (and only a few are on the left hand in the same location).

I take a lot of vitamins and supplements, eat a low fat, high protein diet, exercise 5 days a week, don't smoke, rarely drink and have one latte a day! There is not much sun exposure where I live, but when its nice, I wear sunscreen.

What could be causing the dramatic onset of these spots and should I be concerned?

Hi I'm a 21 yr old black female. I've been having these elevated brown spots on the palms of my hand and the soles of my feet since I was in elementary school. I've talked to physicians and dermatologists and none can explain what it is. My knuckles are also darker and they are a irregular in shape. I just came to believe that it's just a flaw. Does anyone else has this problem?

I also had two small dark spots on my palms that seemed to appear overnight. They are irregular shaped, and about the size of the head of a pencil eraser. They are not really "raised" but feel like patches of rougher skin. They've been on my palms for about 2 weeks now, and today one turned into what looks like a blister. I haven't popped the blister so I'm not sure if it has liquid underneath or if the skin is simply dead and ready to fall off. Neither of the patches are painful or itchy. Any ideas as to what this might be from?

Hi, 30Healthy:

How are your spots now?  Have they gone away without any medication?

I am curious to know, because I also suddently developed age-spots-like tiny brown spots on the back of my left hand, mostly between/on my thumb and index finger.  There are 30 of them, all appeared at the same time.  I did some house cleaning that day and I DID wear gloves.  The spots are flat, light brown, and about 1mm in diameter, except two larger ones that are 3mm and slightly elevated.   They are never red, itchy, scaly, or painful.

I am 40 years old and I don't have any age spots before this.  It has been about a week, not improved.  If your problem has resolved, please share you experience.  Appreciate.

Hi

Skin cancers are usually hyperpigmented or they may show as a bizarre skin manifestation looking like ink blots or even nodular in character eg nodular forms of melanoma. Squamous cell carcinoma and basal cell CA may present on more exposed areas like the face. When have you started noticing these dark spots?

At this point, I do not think this is cancer. The hands are quite sensitive to certain irritants or allergens. This may be a skin reaction. Also, hands are usually exposed to the sun and heat. This may be skin tags or moles.

I suggest that you have this assessed by your dermatologist. This may not be something that you have to be so worried about though I understand your concern. Have this assessed early on to allay your worries.

The spots are slightly elevated.

The only thing I can think of that I did (out of the ordinary) was pull some tall weeds out from underneath a shrub in our front yard. I think the brown spots appeared later that day. It seems maybe that could be the culprit since I pulled the weeds with my right hand & without gloves.

Otherwise, I haven't been using any new creams (other than a foot cream & face moisturizer). I can't imagine those would cause spots on this location of my hand.

Do you know of any skin cancers that show this way?
