There are two possibilities for small white spots on the coronal sulcus of the glans. One may be foreskin scale and the other may be foreskin glansitis. If it is caused by foreskin scale, mainly because the foreskin is too long and there is secretion in the inner plate of foreskin, which gathers in the glans or coronal groove for a long time, there will be small white dot-like foreskin scale. The first thing you need to do is turn your foreskin over and soak it with warm water to get rid of the foreskin scale completely. When there is foreskin glansitis, especially mycobacterial infection, it is more likely to lead to small white dots on the coronal groove of the foreskin glans. Patients rub the small white dots off with their hands and have an itching sensation. The symptoms can disappear quickly with the use of topical application of Dacrynic.
