Stevens-Johnson syndrome and toxic epidermal necrolysis-like cutaneous presentation of chikungunya fever: A case series.

Chikungunya fever is a benign, self-limiting, acute viral illness. An epidemic occurred in New Delhi, India, in August and September 2016. We observed many cases with atypical cutaneous features mimicking Stevens-Johnson syndrome and toxic epidermal necrolysis during this epidemic, especially in infants and children. Twenty-one children (13 [61.9%] boys, 8 [38%] girls) presenting with vesico-bullous and necrotic lesions were reviewed. Cutaneous presentation included vesicles and bullae with purpuric macules and necrosis, seen in 16 (76%) patients. Skin lesions resolved in 5-7 days, leaving behind hyperpigmentation in seven (33.3%) patients and hypopigmentation in three (14.2%). Minor oral erosions were observed in three (14.2%) patients, and palmoplantar erythema was seen in four (19.04%). It is essential for dermatologists to understand the Stevens-Johnson syndrome and toxic epidermal necrolysis-like presentation of chikungunya and not to misinterpret it as true Stevens-Johnson syndrome and toxic epidermal necrolysis, which will lead to unnecessary intervention and management.
