Skin biopsy mainstay diagnosis in suspected lesion SC...
Sir, Prurigos are diseases characterized by intensely pruritic papules and nodules caused by a variety of pathomechanisms. Primary lesions are papules, with or without vesicles, or urticarial lesions. Unlike eczematous reactions, the lesions of prurigo rarely become confluent or form lichenified plaque. Prurigo lesions do not show pustule formation or desquamation. However, prurigos can co-exis...
