I am going to mention 3 works I did not see above that I think have to be on this list.  First, the Shostakovich piano quintet and his piano trio number 2.   I would also add the Prokofiev Concerto #3.    A couple more pieces that I would not necessarily call great works, but works that I perceive to be under appreciated.  Those would be the Copland piano concerto, and Symphony no. 3 by Rued Langaard (you either like Langaard or you don't).  

I'd love to see @devilboy, @schubert, @frogman, and @learsfool weigh in on this thread.  Especially with respect to hidden gems that beg for more play time. 
I wouldn’t call Shostakovich’s Trio #2 for Violin, Cello, and Piano, a piece for piano, but it is certainly one of the great masterpieces of the 20th Century. 
Speaking of Shostakovich, an addition to the many great nominations already made would have to be his “24 Preludes and Fugues”.  Inspired by a visit to J.S. Bach’s home this work is in the mold of Bach’s “The Well Tempered Clavier” in that it offers one prelude and fugue in each of the twelve major and minor keys.  Anyone new to this work should probably start with the recording by Tatyana Nikolayeva (Hyperion) who premiered the work.  

Two nominations for hidden gems would be another Bach inspired work, Ferrucio Busoni’s “Fantasia Contraputtista” and Leos Janacek’s “In The Mists”.  

Since Jazz has been mentioned, I would second the nominations of the Ravel piano works for, not only their greatness in their own right, but also their profound influence on improvising pianists, most notably Bill Evans.
