Recurrent Buccal Kimura’s Disease with Contralateral Parotid Gland, Lymph Nodes, and Subcutaneous Involvement: A Rare Case

Abstract

Kimura's disease (KD) is a rare chronic inflammatory condition predilected in the head-neck region as a painless lump that may mimic malignancy. No previously recurrent KD has been reported in Indonesian males, especially with contralateral involvement. We report a 30-year-old male who had a progressive buccal lump with a history of biopsy-proven KD. Neck US and MRI imaging and histopathology confirmed a recurrence of buccal KD with involvement of the contralateral right parotid gland, bilateral lymph nodes, and subcutaneous buccal region. After superficial right parotidectomy, steroid, and further chemoradiotherapy, postoperative residuals were shown in follow-up CT. Combined neck US and MRI/CT can demonstrate mass extension. Follow-up imaging is important to evaluate mass extensions and residuals.
