Hardened and stinky secretion in the throat what can it be?

Doctor Online has left hardened secretion of my throat looking greenish and strong odor, what can be, please answer me!
Expert answer:

This hard, foul discharge from the throat is called Caseo or Caseum. It consists of a mixture of mucus, dead cells and material accumulated in small orifices of the tonsils, which eventually are expelled. The ideal is to look for an Otorhinolaryngologist who will examine your throat and say what needs to be done, but most of the time the conduct is expectant and palliative.
