Dermatologic Emergencies
Although dermatology may be regarded as a medical specialty with few emergencies, they do exist and range from primary cutaneous disorders to severe systemic conditions with skin manifestations. Prompt recognition for appropriate diagnosis and treatment often is necessary to improve a patient’s prognosis and a single decision can mark the difference between life and death.
Drug Reactions
Cutaneous drug eruptions usually are relatively benign, consisting of a morbilliform eruption often without any other accompanying symptoms. However, sometimes these reactions can present as exfoliative dermatitis or red man syndrome in which patients can develop total body erythema with diffuse scaling and pruritus.4 Aside from drug reactions, other causes of exfoliative dermatitis such as psoriasis, atopic and seborrheic dermatitis, mycosis fungoides, and lymphoma should be ruled out. Other drug eruptions that can be classified as dermatologic emergencies include leukocytoclastic vasculitis, severe urticaria or angioedema, erythema multiforme, or Stevens-Johnson syndrome and toxic epidermal necrolysis.
Severe Acne
If not treated promptly, serious cases of acne can lead to severe scarring and psychologic problems. Acne fulminans is characterized by a rapid eruption of suppurative and large, highly inflamed nodules, plaques, and cysts that result in ragged ulcerations and cicatrization of the chest, back, and occasionally the face. Systemic symptoms of fever, arthralgia, leukocytosis, and myalgia suggest an upregulation of the immune system in affected patients.
Final Comment
In summary, dermatologic emergencies do exist and some may present with characteristic skin findings. In almost all cases, collaboration with other departments such as trauma, burn, internal medicine, rheumatology, and infectious diseases is extremely helpful in diagnosing and treating these medical emergencies. Collaboration can provide insight into how brainstorming through different approaches can lead to a better outcome whether it be solving the cause of a puzzling rash in a patient with multiple comorbidities or surgically removing a bullet from a trauma patient (Figure 4). Recognition of specific cutaneous manifestations and early diagnosis of dermatologic emergencies can be lifesaving.
