Hi, HIV is remote possibility. In geographic tongue
, which is again benign condition, tongue is covered with small protrusions called papillae, red patches on the surface of the tongue bordered by grayish white areas. It is again a familial disorder but fissures are not seen.
Please relax, don't think of HIV, as HIV presentations are associated with many other type of symptoms like recurrent mouth ulcers, herpes attacks, fever, diarrhoea, seborrheic dermatitis etc.
