Widespread metachronous carcinoid tumour metastases to the head and neck: a unique presentation.

Carcinoid tumours are usually slow-growing, neuroendocrine neoplasms that primarily affect the gastrointestinal tract and bronchial tree. Although relatively rare, isolated, single metastasis to the head and neck has been reported. We present a unique case of 6 metachronous carcinoid metastases to both parotid glands, the left submandibular gland, upper lip, and thyroid, over 3 years. To our knowledge, this widespread presentation in the head and neck has not previously been reported. Copyright Â
