Melanonychia describes black pigmentation of the nail plate that results from either melanocyte activation (such as infections, local inflammatory disorders, local trauma affecting the nail plate, numerous systemic conditions, and medications) or melanocyte hyperplasia (such as benign neoplasms or malignant tumors) or blood (resulting from a trauma-associated subungual hematoma). The black dyschromia may include not only the nail plate but also the proximal nailfold. The Hutchinson sign refers to black discoloration of both the proximal nailfold and adjacent nail plate when the underlying pigmented lesion is a malignant melanoma.

The global pandemic caused by COVID-19 led to numerous novel cases of autoimmune and rheumatologic disorders that developed postinfection. Along these lines, these authors report an unusual case of scleredema following SARS-CoV-2 infection in an individual who lacked any known risk factors. Given the emergence of newer mutant strains of COVID-19 and steadily rising numbers of people receiving COVID-19 vaccinations, physicians should remain alert for as yet unrecognized manifestations of the disease.
