>> N = numel(A);
>> X = false(N,N); % find which arrays are the same:
>> for ii=1:N, for jj=1:ii, X(ii,jj)=isequal(A{ii},A{jj}); end, end
>> Y = X & cumsum(X,1)==1 & cumsum(X,2)==1; % indices that ignore duplicates.
>> Z = A(any(Y,1));
>> Z{:}
ans =
1 2 3 4
ans =

You can convert the elements of each cell to a char array and apply unique on that cell array of chars.
A = {[1,2,3,4],[4,2,3],[1,2,5,6,78,9],[1,2,3,4],[1,2,5,6,78,9],[4,2,3],[5,6,7]};
% engine
[~,ix] = unique(cellfun(@(x) num2str(x), A ,'un', 0), 'stable') ;
B = A(ix) % as requested
