A 60-year-old gentleman was intubated due to severe leptospirosis and multi-organ failure: acute kidney injury and liver failure with disseminated intravascular coagulation (DIC). He was ventilated in the intensive care unit for 7 days. He was treated with ceftriaxone, pantoprazole, fentanyl, midazolam, and required frequent fluid challenge and inotropic support.
On the day of extubation, the patient was noted to have ulcers over the angles of the mouth with crusted blood and seropurulent discharge (Fig 1). He also had diffuse erythema and desquamation over the tips of the fingers (Fig 2), and a large purpuric patch over the lateral aspect of both thighs (Fig 3) with generalised scaly dry skin over the body.

He was treated as Stevens-Johnson syndrome (SJS). Antibiotic therapy was stopped and intravenous hydrocortisone was started but his ulcers continued to worsen. A dermatological opinion was arranged and revealed that the oral and tongue mucosa erosions were confined to the site of previous endotracheal tube placement rather than being the diffuse oral and lips erosions of SJS. Nikolsky sign was negative. The conjunctiva was clear, and there was involvement of the nasal, urethral or anal mucosa.
In view of the confined area of mucosa involvement, he was diagnosed with medical device–related pressure ulcers. The purpura and ecchymosis were due to the underlying coagulopathy secondary to septic shock with DIC. Potential infective causes, eg vegetating herpes simplex, staphylococcal scalded skin syndrome, were excluded by negative wound culture. There were also no features of SJS on skin biopsy.
The steroid was stopped immediately and antibiotics resumed. Albumin level was optimised. After 2 weeks of oral care, the patient’s skin condition improved (Fig 4) and he finally attained full recovery.
Tracheal intubation is one of the best methods of airway protection1 but serious complications may occur, especially in critically ill patients.2
Stevens-Johnson syndrome is part of a spectrum of severe cutaneous adverse reactions that affect skin and mucous membranes. It is commonly caused by certain medications or infections. Skin lesions may be purpuric macule spots, erythema, or sometimes violaceous target-like lesions. Mucous membrane erosions and ulcers almost always appear in the eyes, mouth and lips, but may also occur in the upper airway, genitourinary and gastrointestinal tract. Assessment is often difficult when mucous membrane involvement is not yet apparent.3
Hypotensive episodes during septic shock may lead to reduced perfusion pressure to the skin and mucosa. This may cause pressure point areas to develop pressure sores.4 Hypoalbuminaemia and DIC may cause further deterioration of the ulcers. Pressure sores are one of the most common complications among patients undergoing mechanical ventilation in a poorly managed setting.5
Physicians should always be extra cautious when diagnosing SJS. The consensus definition should always be consulted with referral to a dermatologist or performance of a skin biopsy if there is any doubt.3 An incorrect diagnosis of SJS may lead to a totally inappropriate spectrum of treatment such as cessation of appropriate life-saving antibiotics and the commencement of steroid therapy that will increase the risk of infection and impair wound healing.
