(The Lancet) In January, 2009, an 18-year-old man presented to the emergency department after suffering an attack with an incendiary shell. He had many painful patches of full-thickness burns, which were surrounded by sloughed tissue. His wounds covered 30% of his body surface area, and were distributed on both upper and lower limbs, and his right shoulder.

There were no signs of inhalation burns. After a clinical diagnosis of white phosphorus burns was made, the airway was secured, resuscitation fluid was initiated, and wounds were irrigated with diluted sodium bicarbonate solution before wet dressing.

1day after admission to the burns unit, white smoke was noticed emanating from the wounds, which now contained extensive necrotic tissue and had extended into the underlying tissue.

He was urgently transferred to the operating room for debridement and excision of necrotic tissue, and removal of white phosphorus particles. During debridement, a white phosphorus particle was accidentally dislodged resulting in a superficial burn on a nurse’s neck.

We transferred our patient to the intensive care unit for monitoring of vital signs, electrolyte disturbance (in particular hypocalcaemia), and electrocardiogram (ECG) changes.

After 8 days in hospital, our patient was relatively well, and was discharged without any systemic complications.

At 16-month follow-up, our patient was well; however, hypertrophic, mildly tender scars remained on his chest, arm, and thigh.

White phosphorus is a smoke-producing, waxy, yellow transparent combustible solid,1 which is used mainly in military and industrial settings. In the presence of oxygen, it spontaneously ignites with a yellow flame and produces dense smoke; it extinguishes only when deprived of oxygen or totally consumed.2

On contact with exposed skin, white phosphorus produces painful chemical burns;3 these typically appear as yellowish, necrotic, full-thickness lesions due to both chemical and thermal components. Because white phosphorus has high lipid solubility, the injuries often extend deep into underlying tissues with resultant delayed wound healing.

White phosphorus can also be absorbed systemically resulting in multiple organ dysfunction syndrome because of its effect on erythrocytes, kidneys, liver, and heart.2,4

First aid management of white phosphorus burns includes removal of the patient’s clothes and application of saline or a water-soaked dressing.

1 On the basis of animal studies and case reports, in the emergency department, continuous irrigation with water is recommended to minimise the complications of the burn,1, 2, 4 and large easily identifiable particles of white phosphorus should be debrided. Wood lamp (ultraviolet light) or a solution of 0·5% copper sulphate can be used to facilitate the extinction of embedded particles.4

In critically ill patients, excision of the necrotic tissue and skin grafting, plus appropriate fluid replacement, and close monitoring of electrolytes and ECG are required to avoid predictable complications like hypocalcaemia, hyperphosphataemia, and cardiac arrhythmia. White phosphorus burns are associated with significant morbidity often necessitating lengthy hospital stays. Extreme cases can be fatal. We cannot give an estimate of the number of such cases in our burns unit because it is in a war situation in which no formal recording was done; these burns are rarely encountered in practice and literature describing cases is limited.

According to the UN Convention on Certain Conventional Weapons it is prohibited to make civilians the object of attack by incendiary weapons.
