Abstract
Objective To explore the oral mucosal manifestations of Sweet's syndrome and provide a reference for its early detection and correct diagnosis.Methods The oral mucosal manifestations of a 60-year-old female patient with Sweet's syndrome are described in detail,followed by a discussion of the related literature.Results The patient had skin erythema of both lower extremities,which was accompanied by oral mucosal ulceration and pain for 3 days.The patient presented with mild cutaneous lesions and diffuse large-scale erosion in the oral mucosa with obvious pain.During the onset of the disease,the patient was accompanied by fever with a temperature of 38.5℃.After visiting the Department of Stomatology,laboratory tests showed an increase in C-reactive protein(35.2 mg/L)and an accelerated erythrocyte sedimentation rate(77.00 mm/h).Scattered red plaques and mild tenderness were observed in the knees and lower limbs.Histopathological examination of the skin lesions revealed scattered infiltration of immature neutrophils across the entire dermis.The patient responded well to glucocorticoid therapy.According to the clinical signs and labo-ratory examination,combined with the lesion histopathological results,a diagnosis of Sweet's syndrome was given.The patient was administered 1 mL compound Betamethasone injection only once intramuscularly.In the meantime,the pa-tient was asked to gargle with compound chlorhexidine solution and topically apply recombinant bovine basic fibroblast growth factor solution to the damaged mucosa three times a day for 1 week.After 4 days of medication,the patient's body temperature had returned to normal and the oral lesions were significantly reduced.After 2 weeks,the erythema in the leg and knee had almost all subsided,and the oral mucosal lesions had disappeared.The patient was followed up 6 months after treatment,with no recurrence of skin lesions.After 2 years of follow-up,the disease was stable with no re-currence.A review of the relevant literature shows that Sweet's syndrome is a rare inflammatory reactive dermatosis with unknown etiology,which can be divided into three clinical types:specific,tumor-related,and drug-induced.The male/female prevalence ratio is 1:4.The salient clinical manifestations are abrupt onset of painful erythematous plaques or nodules most commonly involving the extremities,often accompanied by pyrexia,elevated neutrophil count,elevation of the erythrocyte sedimentation rate,and positive C-reactive protein.The use of glucocorticoids is the most common treatment for this disease,and most patients see a rapid improvement in skin lesions;however,some may experience infection or recurrence after withdrawal.Some patients with Sweet's syndrome are accompanied by oral lesions,but cases of oral mucosal damage have been rarely reported,and this condition is easily misdiagnosed.Conclusion Oral mucosal lesions may be extraterritorial manifestations of Sweet's syndrome,and the patient's systemic condition should be comprehensively considered.Skin biopsy should be completed as soon as possible to make a clear diagnosis,so as not to delay the disease.J Prev Treat Stomatol Dis,2024,32(8):620-624.关键词
