Onychodystrophy with Multiple Epiphyseal Dysplasia: Literature Review.
Overview
abstract
INTRODUCTION: Onychodystrophy has been described in association with certain bone disorders, including Nail-Patella Syndrome, Hutchinson-Gilford Progeria Syndrome, Coffin-Siris Syndrome, and congenital brachydactyly. However, nail changes associated with multiple epiphyseal dysplasia (MED) has not been documented. CASE PRESENTATION: An 11-year-old male with history of MED presented with thickened, dystrophic appearing fingernails. Physical examination was significant for fingernail longitudinal ridges and grooves, thinning, and distal splitting. Dermoscopy revealed superficial desquamation. Nail clippings were negative for microbial pathogens. Hand X-rays showed brachydactyly, shortening of the metacarpals, and sclerotic epiphyses of the bilateral 5th distal phalanges and right 2nd distal phalanx. CONCLUSION: This is the first documented case of MED with onychodystrophy, supporting the link between phalangeal formation and nail development. It is important to perform a careful examination of the nail units in patients with skeletal dysplasia and screen patients with characteristic and unexplained nail changes for bony changes. Living with skeletal disease is extremely challenging, and treatment of associated nail disease can improve quality of life for these patients.
