Indian Journal of Dermatology, Venereology and Leprology. 2008 May-Jun; 74(3): 257-9http://imsear.searo.who.int/handle/123456789/52019Median canaliform deformity of the nail is an uncommon entity, where there is longitudinal splitting of the nail. Longitudinal splitting of the nail is a rare phenomenon and can also occur following number of growths arising in the nail matrix. On examination there was a longitudinal split in the nail plate, beginning in the distal nail fold and extending proximally all the way to the proximal nail fold. There was a small, almost indiscernible, swelling in that area, which was exquisitely tender. The split part of the nail showed a little discoloration. There was no discharge, bleeding, or subungual mass visible. 'Love test' was positive in this case. After nail avulsion, a small 2 mm x 4 mm nodule was exposed and excised. Histopathological examination of the tumor showed a mantle of glomus cells surrounding the blood vessels.engAgedDiagnosis, DifferentialGlomus Tumor --complicationsHumansMaleNail Diseases --diagnosisNails --pathologyPain --etiologySkin Neoplasms --complicationsThumbGlomus tumor-induced longitudinal splitting of nail mimicking median canaliform dystrophy.Case Reports
