Thanks for writing to us.,
You have not indicated the colour and size of the patches present on the ?? abdominal area.Only probabalities can be said at this stage.
Whether they are present since birth.If so kindly get yourself checked by a Neuro Surgeon.If a "Cafe-au lait " patch is present on a particular dermatome, it is neurologically significant in that there could be a dormant Neurofibroma
. If it is present in the spinal cord
it could bring pressure effects.
If it is aquired due to tanning of skin it will not be well defined with limited borders but will de diffuse .In that case sunscreening lotions containing Paraminobenzoic Acid such as Ointment / cream Melalite can be applied 30 mins before going to sun.Vitamin C
500 mg PO daily can be used to prevent overtanning of skin .
Kindly undergo Skinbiopsy by a qualified Dermatologist
to ascertain the type of lesion.
It could even be Idiopathic Guttate Hypermelanosis
(IGH) which is absolutely normal and no need to worry at all.
Wishing you all the very best.,
Dr Lt Cdr ASN Bhushan.,
