Onychomatricoma is a rare benign fibroepithelial tumor of the nail complex. The tumor is more frequent in middle-aged Caucasian women presenting chirodactyls. Trauma is the main etiological factor. Clinical presentation is characterized by a brownish hyperkeratotic longitudinal strip of variable thickness, splinter hemorrhages affecting the proximal portion of the nail plate preferentially, longitudinal and transverse hyper- curvature of the nail plate and digitiform projections that emerge from the nail matrix. In addition, it can be observed cavitations in the nail plate, structures that are best visualized after surgical exeresis of the lesion. It mimics many other conditions and tumors, and biopsy and histopathological analysis are essential for diagnostic confirmation.
