Salivary gland pathology in the paediatric population is rare and can present management challenges regarding both investigation and treatment.

Case report and review of available literature.

A seven-year-old, fit, well girl presented with a two-month history of a painless mass over the left parotid area. Ultrasonography confirmed the presence of a well-defined, 1.5 × 2 cm, predominantly solid lesion with minor internal cystic spaces arising from the superficial part of the gland. Magnetic resonance imaging showed no invasion of the deep lobe or skeletal erosion. Superficial parotidectomy was performed via a facelift incision. Histopathology confirmed a diagnosis of pleomorphic adenoma. Review of the literature emphasised important differences in managing this pathology in the paediatric population when compared with adults.

We present the youngest reported case of a pleomorphic adenoma of the parotid gland, detail its management, and discuss the general approach to parotid pathology management in the paediatric population.

Formalin is a saturated aqueous solution comprising 37–40 per cent formaldehyde. It is often used in histopathology laboratories as a tissue preservative. The ingestion or injection of formalin has an immediate, powerful and destructive impact on humans. This paper reports a case of formalin injection and reviews the relevant world literature.

A 36-year-old male attempted suicide by injecting formalin into the right side of his neck, resulting in a critical airway situation. An endotracheal tube was inserted and a tracheostomy was then performed to secure his airway. After receiving medical treatment, including antibiotics and N-acetyl cysteine, the status of the patient's airway improved.

When examining patients who have injected substances into their neck, the possibility of deep neck inflammation with airway compromise should be considered. Immediate management, which should include establishment of a definitive airway and prophylactic infection control, is crucial.
