VST images of FCSS J033710.0-354727 in g band with different contrasts to emphasize the morphology of the galaxy close to center. The highest level increases from left to the right. Labels are the same as in Figs. 1 and 2. The three circles indicates the bright blobs of light along the northern arm of the polar structure. The cross signature in each panel follows the bright path of the polar structure up to the galaxy center (see Sect. 3 for details). North is up and east is on the left.
