On visual and palpatory clinical examination, a free and well-defined rounded nodule was found, with the tongue showing normal color, but with an enlarged aspect in the central region (Figure 1).
Ultrasonography showing a circumscribed nodular lesion. The echographic aspect was suggestive of a foreign body inside, suggesting an image compatible with a thorn, with granuloma formation.

The echographic aspect suggested a foreign body inside, showing an image compatible with a spine, with granuloma formation (Figure 2).
Surgical access performed through a linear incision in the lingual dorsum on the left side, close to the most superficial region of the lesion.

Surgical access was performed through a linear incision in the lingual dorsum on the left side, close to the most superficial region of the lesion (Figure 3).
Divulsion of the lesion, using blunt-tip instruments, from the adjacent tissue planes, having been cleaved without the rupture of its evident lining capsule.

The lesion was divulsed, using blunt-tipped instruments, from the adjacent tissue planes, having been cleaved without the rupture of its evident lining capsule (Figure 4).
Histopathological examination showing a fragment of a fibrous tissue nodule well delimited by means of a capsule, with thick collagen fibers richly peripherally vascularized and with sparse chronic inflammatory cells, in addition to numerous macrophages that stand out in the midst of immune-inflammatory cells: (a) 50x magnification: the full black arrows represent the outer limit of the fibrous capsule, and the black asterisks represent the peripheral vascular congestion; (b) 100x magnification: the full black arrows represent the bundles of collagen fibers; (c) 200x magnification: the black asterisk represents the chronic inflammatory infiltrate; (d) 400x magnification: the full black arrows represent numerous macrophages in the middle of the chronic inflammatory infiltrate.

After total enucleation without compromising the capsule (Figure 5), the synthesis was performed both in deep muscle planes and on the epithelial surface using simple isolated points.
