Management of cystic cervical metastasis

An adult older than 40 years present with a cystic lump in the upper neck should be considered at risk of having an underlying malignancy of the head and neck-a mucosal squamous cell carcinoma or a papillary thyroid carcinoma. Although the likelihood of malignancy is small, should the diagnosis of malignancy be confirmed pathologically, this consequential diagnosis will result in devastating physical and psychologic upset to the patient and their caretakers, the treating surgeons, and possibly many other clinical groups. It is therefore recommended that all such patients be investigated by radiologic imaging-CT/MRI and fine needle aspiration cytology, followed by panendoscopy of the head and neck, which includes an ipsilateral tonsillectomy biopsy and an excision biopsy of the cystic neck lesion. Should the lesion prove to be an isolated cystic metastatic squamous cell carcinoma, a neck dissection should be performed with or without adjuvant radiotherapy. Should the lesion prove to be a metastatic papillary thyroid carcinoma, a total thyroidectomy and neck dissection should be performed. In general, patients with cystic metastasis have a better prognosis than patients who present with a noncystic neck mass.
