Unusual presentation of primary squamous cell carcinoma involving the interdental papilla in a young woman.

A 33-year-old woman presented with what looked like an epulis at the interdental papilla between 22 and 23. We excised the lesion and histopathological examination surprisingly showed the presence of a well-differentiated squamous cell carcinoma that was not invading the underlying bone. We then did a radical excision including extraction of teeth followed by bony reconstruction. No recurrence or metastases have been seen during a follow-up of 12 months.
