RESUMEN
BACKGROUND: Management of lateral cystic neck masses with no apparent upper aerodigestive tract primary tumour in adults is controversial. Imaging modalities and fine needle aspiration cytology often struggle to distinguish the presence of malignancy. METHOD: This study entailed a multicentre retrospective review of all patients with isolated lateral cystic neck masses from 2012 to 2018 in three Welsh health boards, utilising demographic data and first-line investigations (ultrasound scanning and fine needle aspiration cytology) to develop an evidence-based predictive tool for risk of malignancy. RESULTS: It was found that 29.1 per cent of cystic lesions were malignant on final histology. Age, male gender, non-benign ultrasound scan findings and fine needle aspiration cytology were significant risk factors on univariate analysis. The final multivariate analysis predicted a risk of malignancy ranging from 2.1 to 65.0 per cent depending on the covariate pattern. Smoking status was non-significant. CONCLUSION: A rigorous, risk-stratified approach to the management of these patients should aid the clinician in minimising morbidity and optimising resources.

OBJECTIVES/HYPOTHESIS: There is little evidence to support the removal of thyroid tissue during total laryngectomy. Although oncological control of the tumor is the priority, thyroidectomy can lead to hypothyroidism and hypoparathyroidism. This study aimed to test the usefulness of preoperative computed tomography in predicting histological invasion of the thyroid. STUDY DESIGN: Ambispective cohort study. METHODS: All patients undergoing total laryngectomy for squamous cell carcinoma at one center from 2006 to 2016 were included. Data were recorded prospectively as part of the patients' standard care, but were collated retrospectively, giving this study an ambispective design. The histology report for thyroid invasion was taken as the gold standard. The computed tomography report was categorized by invasion of tumor into intralaryngeal, laryngeal cartilage involvement, and extralaryngeal tissues. RESULTS: Seventy-nine patients were included. Nine patients had thyroid involvement on histology, translating to an incidence of 11.29% in this population. The positive predictive value for cartilage involvement on computed tomography for thyroid invasion was 52.9% (95% confidence interval [CI]: 28.5%-76.1%) and the negative predictive value was 100% (95% CI: 92.7%-100%).The positive predictive value for extralaryngeal spread on computed tomography for thyroid involvement was 100% (95% CI: 62.9%-100%), and the negative predictive value was also 100% (95% CI: 93.5%-100%). CONCLUSIONS: This study has shown that preoperative computed tomography is an effective method of ruling out thyroid gland invasion. The absence of extralaryngeal spread on computed tomography has been shown to be the most useful finding, with a high negative predictive value and a narrow 95% CI. LEVEL OF EVIDENCE: 4.

The authors report the case to understand this unusual presentation and prognosis of mucoepidermoid carcinoma following treatment. We present a case of mucoepidermoid carcinoma in a 67-year-old man. The cancer was diagnosed in the right side of his neck but the primary tumor remained unknown despite attempts at staging. The neck was treated successfully and followed up for 2 years. Metastasis of the primary lesion to the left triceps was diagnosed following a swelling noticed by the patient during the 2-year follow up period. Mucoepidermoid carcinoma can be a low, intermediate or high-grade malignancy and can metastasize to different parts of the body. However, this is the first case report of a metastasis to the triceps muscle.
