Management of Rapidly Progressing Skin Lesions

Evaluation and Diagnosis

The British Journal of Dermatology recommends a thorough physical examination, including vital signs and evaluation of all skin surfaces and mucous membranes, to identify signs of severe conditions such as Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN), severe infections, or autoimmune blistering diseases 1, 3
The Journal of Clinical Oncology suggests documenting the percentage of body surface area (BSA) involved, using body maps and serial photographs to monitor progression, with classifications of <10% BSA (Grade 1), 10-30% BSA (Grade 2), and >30% BSA (Grades 3-4) 3, 1, 4
Immediate laboratory investigations within the first 24 hours, including complete blood count, C-reactive protein, renal and liver function, coagulation studies, glucose, and electrolytes, as well as bacterial cultures and skin biopsies, are recommended by the British Journal of Dermatology and the Journal of Clinical Oncology 1, 3
Ophthalmological evaluation by an experienced specialist is necessary if there is suspicion of SJS/TEN or mucosal involvement, as recommended by the British Journal of Dermatology 1

The British Journal of Dermatology recommends gentle cleaning of the blister with antimicrobial solution, avoiding rupture, and applying a non-adherent dressing if necessary 5, 2, 6
The British Journal of Dermatology also suggests perforating the blister at its base with a sterile needle to facilitate drainage, and applying gentle pressure with sterile gauze 5, 2
Leaving the blister roof intact to act as a natural biological dressing, reducing the risk of infection and promoting re-epithelialization, is recommended by the British Journal of Dermatology and Praxis Medical Insights 5, 2, 6
Applying a gentle emollient, such as white petrolatum 50% with liquid paraffin 50%, to support barrier function, reduce water loss, and promote re-epithelialization, is suggested by the British Journal of Dermatology and Praxis Medical Insights 5, 2, 6

For blisters covering <10% BSA, asymptomatic and non-inflammatory, observation or local wound care only is recommended by the Journal of Clinical Oncology, without the need to discontinue systemic treatments if the patient is receiving them 3
For blisters covering 10-30% BSA (Grade 2), the Journal of Clinical Oncology recommends suspending any potentially causative medication, consulting with dermatology, and initiating high-potency topical corticosteroid (Class 1) such as clobetasol 0.05% or betamethasone, with re-evaluation every 3 days for progression or improvement 3, 6
For blisters covering >30% BSA (Grades 3-4), immediate hospitalization under the supervision of a dermatologist or multidisciplinary team specialized in skin failure is recommended by the Journal of Clinical Oncology and the British Journal of Dermatology, with intravenous methylprednisolone (or equivalent) 1-2 mg/kg, converting to oral steroids when appropriate, with gradual reduction over at least 4 weeks 3, 1

Daily monitoring for signs of infection, such as erythema, purulent discharge, fever, or increased pain, is recommended by Praxis Medical Insights and the British Journal of Dermatology 6, 2, 1
Daily washing with antibacterial products to reduce colonization is suggested by Praxis Medical Insights 2
Bacterial and viral cultures from erosions with clinical signs of infection are recommended by Praxis Medical Insights and the British Journal of Dermatology 2, 1
Topical antimicrobials (silver-based products) should only be applied to areas with clinical signs of infection, not prophylactically, for short periods, as recommended by Praxis Medical Insights and the British Journal of Dermatology 6, 2, 1

Not assuming a simple friction blister when there is rapid progression within 24 hours, as this may suggest a more severe underlying condition, is recommended by the British Journal of Dermatology and the Journal of Clinical Oncology 1, 3
Not delaying skin biopsy, which is essential for definitive diagnosis and should include a sample for direct immunofluorescence, is recommended by the British Journal of Dermatology and the Journal of Clinical Oncology 1, 3
Not applying topical antimicrobials prophylactically to all blisters, but rather reserving them for areas with clinical signs of infection, is suggested by Praxis Medical Insights and the British Journal of Dermatology 6, 2, 1
Not routinely de-roofing blisters, as the roof acts as a protective biological dressing, is recommended by the British Journal of Dermatology and Praxis Medical Insights 5, 2, 6
Not underestimating the need for urgent ophthalmological evaluation if there is any mucosal involvement, is recommended by the British Journal of Dermatology 1
