Hello and welcome to HCM
Pigmented spots all over the body indicates an abnormality or a proliferation of melanocytes/ pigment containing cells in skin.
Some of the pigmented lesions are present since birth and they are commonly known as moles
Majority of the moles are benign and are called naevus.
Any change in size, shape or color of these moles should be promptly reported to the doctor.
These type of changes can be due to malignant change in the moles.
You have mentioned that there is re-appearance of the brown spots/ moles, the moles are even worse than before and they turn light.
The nature of lesion can be determined by studting the biopsy
taken from the lesion.
Consult your dermatologist
for clinical examination, biopsy/ other relevant investigations and management.
Thanks and take care
