Norwegian scabies or crusted scabies is a rare manifestation of scabies which is characterized by heavy infestation by scabies mite along with crust formation. Scabies per se is a contagious condition transmitted through direct contact with an infected person and has frequently been associated with institutional and health care facility outbreaks. The subtype Norwegian scabies, characterized by heavy plaque formation has been frequently reported to be masquerading as other dermatological diseases. A 80 year old male patient was admitted with a five month old history of  having developed multiple, erythematous plaques with crusting all over the body. The lesions were initially pruritic but gradually were reported as non pruritic and this hampered the initial diagnosis. The skin biopsy was performed and the final diagnosis of crusted scabies was reported.
