  We consider electroweak singlet dark matter with a mass comparable to the
Higgs mass. The singlet is assumed to couple to standard matter through a
perturbative coupling to the Higgs particle. The annihilation of a singlet with
a mass comparable to the Higgs mass is dominated by proximity to the W, Z and
Higgs peaks in the annihilation cross section. We find that the continuous
photon spectrum from annihilation of a perturbatively coupled singlet in the
galactic halo can reach a level of several per mil of the EGRET diffuse gamma
ray flux.
