Ectopic carcinoma ex-pleomorphic adenoma in the lower neck: a rare entity at a rare location
Keywords:Carcinoma ex-pleomorphic adenoma; pleomorphic adenoma; ectopic salivary gland; neck
Ectopic salivary gland tissue (ESGT) is salivary tissue located outside the major, minorand accessory salivary glands. Neoplasms rarely arise from ESGT, let alone carcinoma expleomorphicadenoma (CEPA) which is a malignant tumour that arises from the epithelialcomponent of pleomorphic adenoma. It usually occurs in the parotid gland and in lesserinstances, from submandibular gland or minor salivary glands. Herein, we report a rare caseof CEPA in right supraclavicular ESGT of a 67-year-old lady.She underwent complete surgicalexcision of the mass and is free from any recurrence to date. Brief review of pathogenesis,clinical features and treatment of ectopic CEPA are discussed. A thorough review of the Englishliterature reveals that our patient may be the second case of ectopic CEPA in the neck regionever reported to date.
