Heterotopic salivary tissue (HST) is a normal salivary tissue located outsides the major and minor salivary glands. Multiple sites of localisation of heterotopias have been described, the occurrence of HST in the neck is rare and it may have several clinical manifestation. We report the case of 72-year-old Caucasian man presenting a suspect mass on the left-sided supraclavicular region. He is known for melanoma of the right elbow, surgically treated 11 years ago. The final diagnosis of pleomorphic adenoma of HST was retained. Methods of diagnosis and management are documented. Neoplasms arising from HST are uncommon with approximately 80% of benign tumours. Warthin's tumour is the most frequent. The localisation of these neoplasms in the lower neck is very rare and often causes a diagnostic pitfall. Histological analysis provides certainty of diagnosis, defines management and follow-up.
