Based on the history and images you have shared, it seems like natural marks since birth but if it had been acquired after surgery and you are quite sure about it, it can melasmas which is due to increased pigmentation at different sites.
If it is due to surgery it will resolve in few months and are neither contagious or dangerous but if you are seriously concerned about it's prescence, a dermatologist review can be sought to use peeling agents available locally to be used over it for few weeks.
