  FS CMa stars are low-luminosity objects showing the B[e] phenomenon whose
evolutionary origin is yet to be unraveled. Various binary-related hypotheses
have been recently proposed, two of them involving the spiral-in evolution of
the binary orbit. The latter occurs more often in dense stellar environments
like young massive clusters (YMCs). Hence, a systematic study of FS CMa stars
in YMCs would be crucial to find out how these objects are created. In YMCs,
two FS CMa stars have been confirmed and three candidates have been found
through a search method based on narrow-band photometry at Paschen-$\alpha$ and
the neighboring continuum. We apply this method to archival data from the
Paschen-$\alpha$ survey of the Galactic Center region, yielding a new candidate
in the Quintuplet cluster. Limitations of this method and other alternatives
are briefly discussed.
