Am J Dermatopathol. 2021 May 5. doi: 10.1097/DAD.0000000000001871. Online ahead of print.


Primary cutaneous aspergillosis is a cutaneous fungal infection due to the direct inoculation of spores of Aspergillus species into the disrupted skin. Primary cutaneous aspergillosis presents with a variety of localized cutaneous lesions, such as erythematous macules, papules, plaques, or nodules that can progress to necrosis, erosion, ulceration, or fistulization. Many species of Aspergillus can cause the disease, and one of them is Aspergillus niger that rarely affects immunocompetent patients and that has peculiar characteristics on the histopathological examination. We present a series of 4 cases of immunologically competent patients presenting with primary cutaneous aspergillosis caused by A. niger.
