Toxic epidermal necrolysis complicated with primary cutaneous aspergillosis: A report of four cases.

Primary cutaneous aspergillosis (PCA) is a rare opportunistic infection caused by Aspergillus that can be life‐threatening. PCA is mainly reported in immunocompromised hosts such as patients with AIDS, those with hematologic malignancy, or infants with occlusive dressings. However, no study has previously reported PCA associated with toxic epidermal necrolysis (TEN). This study reports four cases of TEN complicated with PCA, presenting with discrete gray or black spots over newly formed epithelia. Risk factors of PCA in patients with TEN include host factors, iatrogenic factors, indoor environment, and wound care. Two of the four cases eventually died, highlighting the importance of further exploring PCA in patients with TEN. [ABSTRACT FROM AUTHOR]
