  We show that the gamma ray spectrum observed with the HESS array of Cherenkov
telescopes coming from the Galactic Center (GC) region and identified with the
source HESS J1745-290, is well fitted by the secondary photons coming from dark
matter (DM) annihilation over a diffuse power-law background. The amount of
photons and morphology of the signal localized within a region of few parsecs,
require compressed DM profiles as those resulting from baryonic contraction,
which offer $\sim 10^3$ enhancements in the signal over DM alone simulations.
The fitted background from HESS data is consistent with recent Fermi-LAT
observations of the same region.
