  We investigate the small-mass asymptotics of a class of massive $d$
dimensional angular integrals. These integrals arise in a wide range of
perturbative quantum field theory calculations. We derive expressions
characterizing their behavior in the vicinity of the massless limit for all
cases with up to two denominators. The results established in this work are
applicable to phase-space calculations where an integration over virtuality
including the massless limit is required.
