Sialadenoma papilliferum in a young patient: a case report and review of the literature.

Sialadenoma papilliferum is a rare exophytic tumor of salivary gland origin, accounting for less than 1% of minor salivary gland tumors. It usually occurs in males older than 50 years as a painless papillary intraoral lesion. An 18-year-old male patient presented with an exophytic intraoral lesion present for approximately 12 years. The tumor was excised with a clinical diagnosis of infected hemangioma. However, histopathological diagnosis was consistent with sialadenoma papilliferum. The patient was followed up at regular intervals and no evidence of recurrence was noted. Our patient, aged 18 years, with tumor lasting for 12 years becomes the youngest case of intraoral sialadenoma papilliferum yet reported. This case highlights the importance of keeping sialadenoma papilliferum as a differential diagnosis of an intraoral exophytic proliferative lesion even in a young patient.
