Norwegian (crusted) scabies is a rare but highly contagious variant of scabies that predominantly affects immunocompromised individuals, such as those with diabetes or neurological disorders. The condition is characterised by hyperkeratotic plaques teeming with mites, often leading to secondary bacterial infections and life-threatening complications. We present a fatal case of Norwegian scabies in a 65-year-old male with epilepsy and diabetes, who developed severe skin infestation, staphylococcal bacteremia, and multi-organ failure. Despite receiving aggressive treatment with oral ivermectin, topical permethrin, and IV antibiotics, the patient deteriorated and succumbed to sepsis. This case highlights the importance of early diagnosis, aggressive management, and strict infection control to prevent adverse outcomes.
