  Present and future high-precision tests of the Standard Model and beyond for
the fundamental constituents and interactions in Nature are demanding complex
perturbative calculations involving multi-leg and multi-loop Feynman diagrams.
Currently, large effort is devoted to the search for closed expressions of loop
integrals, written whenever possible in terms of known - often
hypergeometric-type - functions. In this work, the scalar three-point function
is re-evaluated by means of generalized hypergeometric functions of two
variables. Finally, use is made of the connection between such Appell functions
and dilogarithms coming from a previous investigation, to recover well-known
results.
