We study the problem of equiconvergence on \mathbb T^3=[-\pi, \pi)^3 for expansions in a triple trigonometric Fourier series and a Fourier integral of continuous functions with a certain modulus of continuity in the case of a "lacunary sequence of partial sums".

Key words: multiple trigonometric Fourier series, multiple Fourier integrals, convergence almost everywhere, lacunary sequence.
