Ladder diagrams for Compton scattering of a massless scalar photon by a scalar nucleon are evaluated in the large t limit. The leading term in the 2n-th order is found to be (ln t)^<2n-2>/t, compared to (ln t)^<n-1>/t for the case of scattering of two scalar particles of finite masses. In terms of partial waves, the 2n-th order diagram gives a leading singularity 1/(l+1)^<2n-1> at l=-1, compared to 1/(l+1)^n for the finite mass case. Regge poles generated by summing ladder diagrams and the corresponding large t behavior are discussed.
