Unusual neoplasm on the hard palate of a child: a case report

Mathangi Kumar et al. J Med Case Rep. .

Abstract

Background: Myoepitheliomas account for less than 1% of salivary gland tumors. They mostly affect the parotid glands of adults during the third to fifth decades.

Case presentation: A 10-year-old Indian boy reported a small swelling in the roof of his mouth of 10 days' duration. History revealed that the lesion was painless and not associated with bleeding or pus discharge. On examination, a purplish well-circumscribed growth was noted on his posterior hard palate. Magnetic resonance imaging was suggestive of a well-encapsulated hemangioma. An excisional biopsy was performed and histopathology along with immunohistochemistry analysis showed that the lesion was a spindle cell variant of benign myoepithelioma.

Conclusion: Palatal myoepitheliomas are rare and their occurrence in young individuals is rarer.

Keywords: Hemangioma; Myoepithelioma; Oral cavity; Pediatric; Salivary gland tumor.
