Salivary duct carcinoma of submandibular gland with trigeminal nerve invasion to intracranium.
Salivary duct carcinoma is a rare and invasive malignant tumour with rapid distant metastasis and dismal prognosis. Clinically, perineural invasion of the salivary duct carcinoma is commonly noted. Here, we present a case of salivary duct carcinoma of submandibular gland origin with perineural invasion of the trigeminal nerve proximal to the intracranium, that was well demonstrated by a magnetic resonance image (MRI) and was consistent with the clinical presentation. This case received radical resection and radiotherapy with inclusion of the skull base within the field. There was no tumour recurrence and distant metastasis 24 months post-operatively.
