Abstract

A 15-year-old boy presented with swelling in the submandibular region. X-ray of the swollen part showed faint radio opaque shadow. A provisional diagnosis of sialadenitis with sialolithiasis was made. Excised mass was reported histopathologically as plexiform neurofibroma of submandibular salivary gland.Plexiform neurofibroma of the salivary gland is a rare benign tumor often present in the parotid gland. It is very rare in submandibular salivary gland. It is a slow growing, locally infiltrating tumor.

Highlights

  • Neurofibromas constitute only 0.4% of all salivary neoplasms

  • Plexiform neurofibromas of the salivary glands are rare, usually presenting in the parotid gland. They are very rare in submandibular salivary gland

  • Plexiform neurofibromas are frequently seen in patients with Type I neurofibromatosis and undergo malignant changes in 2% of the cases

Summary

INTRODUCTION

Plexiform neurofibromas of the salivary glands are rare, often presenting in the parotid gland. They are very rare in submandibular salivary gland.[1,2] They are slow growing, locally infiltrating tumors. Five cases are reported so far in the literature.[3] Probably this is the sixth one. We are presenting this case because of its rarity of presentation. A firm swelling in the submandibular region of size 8 x 5 cm, with ovoid shape and well-defined borders was present.
