Linear And Punctate Porokeratosis Associated With End-Stage Liver-Disease

A periodic eruption of porokeratosis developed in a 31-year-old black woman with chronic idiopathic hepatitis requiring liver transplantation. The clinicopathologic features were chiefly those of linear and punctate porokeratosis but overlapped those of porokeratosis plantaris, palmaris et disseminata and hyperkeratotic or verrucous porokeratosis. Typical cornoid lamellae were visible on histologic examination. Outbreaks of the lesions occurred during exacerbations of the liver disease. The skin condition rapidly improved after operation, with concomitant improvement in liver function.
