Microscopic examination of the excised specimen revealed fibrocollagenous connective tissue with dispersed spindle-shaped fibroblasts and bigger stellate cells with 1 or 2 nuclei (Figure 1).
Stellate giant cells in close proximity to the overlying epithelium,
which forms elongated rete pegs (Case report 1, hematoxylin and eosin
stain, original magnification x100).

Caucasian boy was referred for dental restoration. Clinical examination revealed the presence of a hyperplastic lesion in the interproximal area between the left deciduous mandibular lateral incisor and canine; the lesion was extending both buccally (3 x 2 mm) and lingually (4 x 3 mm) (Figure 3A, B).
A and B = photomicrographs showing multiple stellate cells dispersed in a
fibrous connective tissue stroma; elongated epithelial rete pegs are
also discerned (Case report 2, hematoxylin and eosin stain, original
magnification x400).
