The coexistence of laryngeal squamous cell carcinoma metastasis and a Warthin tumour in the parotid gland – a case report

Introduction: Metastasis of malignant laryngeal tumours to the parotid gland is rarely described in the literature. The most common tumours metastasising to the parotid lymph nodes are skin tumours: squamous cell carcinoma and melanoma (approximately 70–80% of cases). Cases of the simultaneous occurrence of two tumours in the parotid gland are seldom reported in research. Case report: In this paper, the authors present a case of co-occurrence of squamous cell carcinoma of the larynx metastasising to a salivary gland lymph node alongside a Warthin tumour in the parotid gland. Conclusions: The co-existence of benign and metastatic lesions within the parotid gland may impose diagnostic difficulties. In cases of extensive malignant tumours in the head and neck region, where enlarged lymph nodes and lesions in the parotid gland are found, the treatment of choice remains parotidectomy performed concurrently with lymphadenectomy. The extent of the parotid gland surgery depends on the size and type of lesions in the gland.
