Lingual location of Sweet's syndrome: A case report

Abstract

Context: Sweet's syndrome is a rare acute febrile neutrophilic dermatosis and idiopathic in two-thirds of cases. The pathophysiological mechanisms of Sweet's syndrome are poorly understood. Observation: A 35 yr old female patient has been referred from the Dermatology Department to the Oral and Surgery Department, University Hospital Center of Oran (Algeria), for a lingual nodule. For medical history, the patient had a Sweet's syndrome diagnosed 1 yr ago and a rheumatoid arthritis treated with corticosteroids. An excisional biopsy of the lingual nodule was performed and the anatomopathological result revealed a pyogenic granuloma associated with polymorphonuclear neutrophilic vasculitis in the context of Sweet's syndrome. Discussion and conclusion: Sweet's syndrome is characterized by a constellation of clinical symptoms, biological and histological abnormalities and is manifested by the sudden appearance of painful skin lesions in the form of asymmetric erythematous papules, nodules or plaques. In the context of Sweet's syndrome, faced with an oral with cutaneous lesions a correlation and/or manifestation of neutrophilic dermatosis must be suspected.
