Rare intraparotid gland localization of Kimura's disease: A case report

Introduction and importance: Kimura's disease, a rare chronic inflammatory disorder of uncertain etiology, predominantly affects Asian males. Its occurrence in non-Asian individuals is uncommon, often leading to diagnostic delays. We present a North African case to underscore its global relevance. Case presentation: A 31-year-old male presented with a 6-year history of a firm, mobile parotid mass. MRI identified a nodular lesion in the superficial parotid lobe. Histopathology confirmed Kimura's disease. The patient underwent exofacial parotidectomy with no recurrence. Clinical discussion: Kimura's disease must be distinguished from malignant or infectious parotid masses. Surgical excision is curative for localized disease; corticosteroids address systemic involvement. Renal complications (seen in 50 % of cases) require monitoring. Radiotherapy/immunosuppressants remain adjunctive. Conclusion: This case emphasizes including Kimura's disease in differential diagnoses of parotid masses, regardless of ethnicity. Its diagnosis is based on histopathologic findings, and treatment should be individualized.
