MASSON'S TUMOUR OF ORAL CAVITY: REPORT OF TWO CASES WITH REVIEW OF LITERATURE

Ikbal Hossain, Indranil Deb Roy

Abstract


Background: Intravascular papillary endothelial hyperplasia (Masson’s tumor) is a rare, benign lesion of the skin and subcutaneous tissue with reactive papillary proliferation of vascular endothelial cells. It was first described by Masson in 1923.

Case report: Two cases of asymptomatic, pigmented lesion present since 20 years at right buccal mucosa without any other relevant history. Inspectory findings revealed a bluish red, 2 x 2 cm sized lesion with no secondary changes of overlying mucosa. On palpation, the lesion was nontender, nonpulsating, noncompressible, nonreducible, rubbery in consistency and no blanching on pressure. Auscultation didn’t reveal any thrill or bruit. Based on the clinical findings, a provisional diagnosis of ‘pigmented lesion of right buccal mucosa’ was made. Excisional biopsy of the lesion was carried out under local anaesthesia. Histopathological report described the lesion as hemangiomatous growth with intravascular papillomatous endothelial hyperplasia which is evocative of Masson’s tumour.

Conclusion: Intra oral Masson’s tumor is very rare and less than a hundred cases have been reported in the literature. Clinically and histopathologically these pigmented lesions may behave deceptively mimicking angiosarcoma.
