  In these proceedings, I report on a selection of recent LHC results in small
systems from ALICE, ATLAS and CMS experiments. Due to the fact that the
investigation of QCD in small systems at high multiplicity is becoming an
increasingly large subject, interesting the heavy-ion community and more in
general the high-energy physics community, not all the related topics can be
discussed in this paper. The focus will be given to some of the measurements
addressing the physics of collective phenomena in small systems and to the
recent results on strangeness enhancement in proton-proton collisions. The
reader must be informed that a large number of interesting results did not find
space in the discussion reported here.
