    Abstract:
    Porokeratosis is a keratinization disorder characterized by hyperkeratotic sharply demarcated plaques with central atrophy and histopathologically, by cornoid lamella. A 30-year-old male presented with multiple pruritic dark raised skin lesions over the trunk, face, and upper limbs for past 3 years. Cutaneous examination revealed hyperkeratotic annular plaques with raised margins over face, trunk, and arms. Histopathology revealed marked hyperkeratosis with irregular acanthosis and papillomatosis. Vertical parakeratotic foci and focal hypergranulosis were seen. Hence, a diagnosis of disseminated superficial porokeratosis was made. We present this rare case which may have association with systemic disease, immunosuppression, and malignant transformation.
