[|Human|] I have an open pore/hole right in the middle of my forehead. i can feel a small lump under the skin. i have had this for a year of two. Every now and then i barely touch it and a small white discharge comes out. The discharge does smell bad. any ideas on what it is?
[|AI|]  Hello! Thank you for the query. Bump with small opening/hole is very characteristic for sebaceous cyst. It is a kind of benign skin lesion, filled with whitish masses. Sooner or later, such cyst gets infected. If so, the pus appears which gives bad smell and pain. Redness usually also is present. I suggest you to consult a surgeon with this issue. The lump needs to be removed with surrounding capsule, otherwise it will regrow. Hope this will help. Regards.
