Coxsackie Virus-Associated Onychomadesis in Children: A Clinical-Dermoscopic Presentation

A case report describes infection-related onychomadesis in a 4-year-old patient. The Coxsackie virus infection, which causes hand, foot, and mouth disease, developed with specific symptoms. One month after the end of the illness, the patient began significant changes in their fingernails and toenails. Pathological changes were observed on all fingernails and the first and second toenails. The nail plates were detached from the matrix, and in the middle and distal areas, they adhered to the nail bed. The patient had no history of local trauma to the nails and fingers, no detrimental nail-related habits, and no underlying systemic diseases. Finally, the diagnosis was established based on the patient's medical history, a physical examination of the skin and its appendages, and the dermoscopic findings. The patient's progress was monitored continuously. After two months, the patient's clinical recovery became evident, and the nail plates were completely restored without any structural abnormalities. Although data on onychomadesis associated with coxsackie virus are not so scarce, it remains a topical issue in pediatric dermatology due to its importance and developmental features.
