Benign triton tumour of upper lip- a rare neoplasm at an extremely uncommon site

Benign Triton tumours are exceedingly rare tumours occurring predominantly in young children. Fewer than 20 cases have been reported in literature. The tumours develop as masses in various large nerve trunks, the most common of them being the brachial and the sciatic. They are very rarely encountered in the head and neck region. Neurological symptoms may manifest due to their strategic locations. Various case studies in literature support their benign nature. Early diagnosis and complete excision avoids deformities and other associated complications. We present one such rare case of benign triton tumour of the head and neck region in a 10 year old female child who presented with a diffuse nodular swelling in the upper lip involving the philtrum and extending upto the left ala of the nose along with a brief review of literature.
