An unusual site for an intraoral schwannoma: a case report

Adult sublingual schwannoma with angioma-like features and foam cell vascular change

“…Although eight cases of sublingual schwannomas have been reported, only three have been studied for S100 protein [1,3,7], one of which has also been studied for neuron specific enolase, vimentin and Ki67 [1]. Tumour cells in our case expressed the S100 protein and neuron-specific enolase.…”

“…Schwannomas are benign tumours, extremely rare in a sublingual location, 9 cases being reported since 1960 to our knowledge [1,3,6,7,9,10,[12][13][14][15] (Table I). In the 8 reported cases with available data for review, there is a female gender prevalence of 5 : 3 (women : men).…”

“…In only one of the reported cases the schwannoma was intraglandular [10]. The diagnosis is made on the surgical specimen, after surgical resection, possibly due to their rarity in this setting and to nonspecific clinical complaints [1,3,6,7,9,10,[12][13][14][15]. Similarly to schwannomas in other locations, tumour cells express the S100 protein, neuron-specific enolase, and vimentin [13].…”

Schwannome de la langue : à propos d’un cas et revue de la littérature

“…L'échographie enregistre un signal homogène, hypoéchogène avec renforcement postérieur. Le scanner montre une masse hétérogène ou homogène, isodense par rapport aux parties molles, avec prise de contraste hétérogène [4,6] . L'IRM montre une lésion isointense aux muscles en T1 et hyperintense en T2, avec prise de contraste après injection de gadolinium [11] .…”

Schwannoma with secondary erosion of mandible: case report with a review of the literature

“…The nerve of origin is often not identified at the time of surgical excision, although 8 if presented it is displaced to the side by the expanding tumour. 37 Arda et al 45 presented a schwannoma arising from the parasympathetic fibers of the lingual nerve. They found only a few nerve fibers, which were thought to be the parasympathetic nerve of the sublingual gland, attached to the tumor.…”
