OPEN ACCESS Abstract Keywords Noma is a devastating orofacial gangrenous polymicrobial infection, which is • Noma predominantly seen in malnourished children in developing (especially sub-Saharan) • Cancrumoris countries. The pathogenesis is multifactorial and thought to result from a complex • Orofacial infection interaction between opportunistic, bacterial pathogens, poor oral hygiene, and • Gangrenous infection malnutrition in patients debilitated by severe illness or immunosuppression. The disease is associated with high morbidity and mortality. Only few cases of noma have been described in the Western world and to our knowledge noma have not previously been reported in Scandinavia. We describe a 37-year-old Caucasian male admitted due to acute necrotizing stomatitis advancing to fulminant noma within few days. The case report illustrates that noma should be considered as a differential diagnosis in patients presenting with severe orofacial infections, even in the Western world. ABBREVIATIONS the patient was seen by an Ear-Nose-Throat (ENT) specialist on June 17th. Physical examination revealed necrosis involvingthe ENT: Ear-Nose-Throat inferior gingival mucosa, the alveololabial and alveolobuccal sulci INTRODUCTION right side of the tongue, and the skin of the lower lip.

CASE PRESENTATION A 37-year-old Caucasian man with a large daily alcohol intake was admitted to the local hospital due to somnolence and abdominalia on June 14th 2014. Blood tests revealed electrolyte derangement and signs of acute pancreatitis (Table 1). Figure 1 Photograph taken upon admission.

Along with improvement in the standard of living and decrease in extreme poverty and starvation, noma disappeared from the Western world in the 20th century [5,7]. The disease reappeared in concentration camps during World War II, and more recently it has been described in rare case reports froma few developed countries. In these cases noma has been associated with debilitating disease, intense immunosuppression, and malnutrition in combination with poor oral hygiene [3,5]. On the contrary, nomais still prevalent among malnourished young children (1-4 years old) in developing countries, especially in the sub-Saharan region [1,3,7]. Noma is typically initiated by a gingival ulceration, which progresses to necrotizing gingivitis. Left untreated, the infection may advance to necrotizing periodontitis and stomatitis involving most structures of the oral cavity. The infection spreads rapidly through both soft and hard orofacial tissues and a characteristic [2-3,5].well-defined Perforation blackened of the cheeknecrotic is seencentre in theis majoritytypically of casesseen. alongSequestration with extensive of exposed intraoral bone destructions and teeth occurs [2,5]. spontaneously Figure 2 Computed tomography showing the extent of infection.
