Pincer nail deformity

This nail disorder can be identified in the presence of excessive curvature that increases with the length of the nail and reaches the maximum point on the tip of the nail. At this point, you will see the nail that seems to 'pinch' the fingertips without disturbing the skin epidermal tissue. But often this disease causes pain in the patient's fingertips, where the nails curl to the fingertips.

This disorder is likely to occur in patients with psoriasis, SLE, Kawasaki disease, cancer, end-stage renal disease, and genetic syndromes such as congenital paronisia.
