ZME controller describes an near midair collision where aircraft X cancels IFR and goes VFR; and then aircraft Y is cleared for an ILS approach to the same airport. Aircraft Y cancels IFR and aircraft X comes back on frequency reporting a near miss. Controller is unsure of the other aircraft involved in the near miss since aircraft X does not identify it.

Narrative:
I was in the process of taking over the sector. During my briefing; I heard aircraft X cancel his IFR clearance into hot. Aircraft Y was holding at hossy waiting his turn for a practice approach to hot. The controller that I was relieving cleared aircraft Y for an ILS approach to hot. I took over the sector; and one of the first things I did was switch aircraft Y to advisory frequency at hot and ask the pilot to report his missed approach. A few minutes later aircraft Y reported his missed approach. At the same time aircraft X came back on my frequency to report that some aircraft had gotten very close to his aircraft while he was landing. I asked aircraft X if he was reporting a near miss; and he said he was doing just that. I made sure that aircraft X was safely on the ground; and then I reported the incident to management at memphis ARTCC.I would make double sure that both pilots were aware of each other. In this case the second pilot knew about the first aircraft. There may have been a third aircraft out there that none of us knew about. The pilot of aircraft X did not positively identify the other aircraft.
