1. A 54-year-old Colombian man presents with nail dystrophy of two years’ duration. Physical exam reveals longitudinally banded thickening of the lateral half of the nail plate with yellowish brown discoloration, transverse overcurvature of the nail, longitudinal white lines, and splinter hemorrhages.
Diagnosis: The lesion, diagnosed as onychomatricoma was surgically removed and sent for histopathologic study. Onychomatricoma is a subungual tumor characterized by banded or diffuse thickening, yellowish discoloration, splinter hemorrhages, and transverse overcurvature of the nail plate. Because the condition is not well known, it is often misdiagnosed.
