To report a case of varix of the retromandibular vein within the parotid gland.

Case report, and discussion of the appropriate selection and use of radiological investigation techniques.

A 64-year-old lady who presented with unilateral tinnitus underwent a magnetic resonance imaging scan to exclude a vestibular schwannoma. The magnetic resonance scout images revealed an incidental finding of a hyper-echoic mass within the parotid gland. The mass was most consistent with a pleomorphic adenoma. Ultrasound-guided fine needle aspiration cytology was arranged; the ultrasound identified the mass as a varix of the retromandibular vein and fine needle aspiration cytology was not performed.

A varix of the retromandibular vein is a very rare cause of a parotid mass. Appropriate radiological investigations can prevent unnecessary invasive investigations or procedures.

To discuss the histopathogenesis and treatment choices for synchronous tumours of the larynx.

We present two cases of synchronous laryngeal leiomyosarcoma and squamous cell carcinoma. The first case was an early-stage tumour and the second an advanced-stage tumour of the larynx. Selection of adequate treatment for synchronous tumours is difficult because of different spreading rates and metastatic patterns. Treatment choices for both the primary tumour site and the neck should be related to the stage of the squamous component of the tumour.

In such cases, the tumour location, tumour stage and lymphatic metastases must be carefully evaluated in order to make the optimum treatment choice. Treatment evaluation of the neck should be related to the stage of the squamous component of these synchronous tumours. Partial laryngectomy techniques may be preferred if the extent of the disease permits.
