Past history of loss of lower front teeth since 5 years, associated with swelling and pus discharge. Extra orally, single palpable, mobile, and tender right submandibular lymph node seen. 41,42,43, and 44 were missing. 31 and 45 were mobile. 31, 32 and 45 were migrated..

OPG showed unilocular radiolucency extending from 45 to 31 region, involving the roots of 45 and 31 with scalloped borders. The root of 31 was resorbed.

Spindle shaped cells with wavy and tapered nuclei were seen arranged in fascicles in an haphazard manner. Few chronic inflammatory cells were seen.


   Special Stains Top


Toluidine blue: Purplish mast cells seen

S-100 protein: Focal areas of positivity.


   Discussion Top


Histopathology was suggestive of intraosseous neurofibroma with the differential diagnosis including schwannoma, myxoma, desmoplastic fibroma, and fibrous histiocytoma.

Lack of encapsulation and focal areas of positivity for SI00 protein ruled out schwannoma, as the latter shows encapsulation and diffuse positivity for S-100. Positivity for S-100 protein ruled out myxoma, desmoplastic fibroma, and fibrous histiocytoma.

Presence of mast cells strongly supported neurofibroma.

Solitary intra-osseous neurofibroma of mandible
