Elephantine psoriasis with papillomatosis and alternating hypogranulosis and hypergranulosis

Abstract

Psoriasis is a disease of considerable clinical and histopathological diversity. We report a rare case of elephantine psoriasis responding very well to methotrexate. Histopathology revealed abnormal papillomatosis with finger-like projections in addition to alternating orthokeratosis with overlying hypergranulosis and parakeratosis with overlying hypogranulosis. We believe that this finding may represent an odd histopathologic type in elephantine psoriasis.
