ONYCHOMADESIS AND HAND-FOOT-AND-MOUTH DISEASE.

Hand-foot-and-mouth disease (HFMD) is a common viral affection. Onychomadesis can be associated with HFMD. Seven children (3 boys and 4 girls) aged between 7 and 11 years were consulted during 2018 for an acquired onychodystrophy of the nails from the hands and feet. The anamnesis revealed that all patients were diagnosed with HFMD 3-5 weeks before the appearance of onychomadesis. Onychomadesis is a manifestation that can be associated with HFMD. This occurs on average 4-5 weeks after the infection, the Coxsackie A6 virus being the most commonly agent causing the disease. The pathophysiology of onychomadesis is unclear. Evolution is favorable, the nail rising normally about 9 months in the legs and 3 months in the hands. [ABSTRACT FROM AUTHOR]
