Objectives: To present a case of pleomorphic adenoma arising from heterotopic salivary gland tissue in a supraclavicular lymph node.
Design: Case report
Setting: Tertiary government hospital
Patient: One
Result: A 38-year-old female consulted with a six month history of an enlarging right supraclavicular mass. Fine needle aspiration biopsy was negative for malignant cells. No primary tumor could be demonstrated elsewhere. Excision biopsy was performed and final histopathology revealed pleomorphic adenoma surrounded by a normal lymph node. Atypical tumor cells and mitoses were not found.
Conclusion: Criteria were met for diagnosing heterotopic salivary gland in a supraclavicular lymph node which subsequently developed into pleomorphic adenoma The rare location of the lesion as well as the unusual histopathological result of pleomorphic adenoma arising from a lymph node merited submission of this case report.
Key words: heteroplasia, heterotopic, cancer, metastasis, tumor
