Abstract
In this paper we present the calculation of a scalar pentagon integral with two consecutive massive external legs having an equal mass propagator embedded between them. We also deal with the two situations where the farest external leg is either massive or not. The relevance of the calculation comes from its application in many perturbative QCD calculations as well as in QCD corrections for weak precesses.
