Hydradenitis: The most common cause is something called hidradenitis suppurativa. This isn't dangerous but it can cause a discharge and at times this can smell. It's a condition that tends to get a little worse before stabilizing. The other possible cause is something called an epidermoid cyst, not dangerous but can intermittently cause a white pus to be secreted and sometimes painful.
