Wegener Granulomatosis With Strawberry Gingivitis Mimicking Squamous Cell Carcinoma.

Wegener granulomatosis (WG) is an autoimmune disease characterized by necrotizing granulomatous inflammation primarily affecting the respiratory tract and kidneys. Although head and neck involvement is common, oral manifestations presenting as strawberry gingivitis are rare and have seldom been reported as the initial presentation of WG. We report the case of a 17-year-old female who presented with recurrent gingival hyperplasia, initially misdiagnosed as squamous cell carcinoma based on histopathologic findings. However, imaging studies revealed no evidence of malignancy, prompting further diagnostic evaluation. Careful review of the laboratory and histopathologic findings ultimately led to the diagnosis of WG. Subsequent treatment with prednisolone led to partial resolution of the lesions. This case highlights the importance of considering WG in the differential diagnosis of atypical oral lesions to avoid misdiagnosis and ensure appropriate treatment.
