Kimura's disease (KD) is a rare, chronic inflammatory disorder, which is characterized by tumor-like masses mainly located in the head and neck region. Extraocular muscle involvement in KD is uncommon. We report a case of KD that involved both the extraocular muscles and buccal area. A 13-year-old male presented to our clinic with a two-year history of exophthalmos of the left eye and facial swelling. Facial CT and MRI showed a 1.5 x 1.5 cm2 soft tissue mass located at the left masticator and buccal area, exophthalmos of the left eye, and diffuse thickening of the left extraocular muscles. We performed a lateral rectus muscle incisional biopsy of the left eye. Oral methylprednisolone therapy was initiated and tapered following the incisional biopsy.

We report the first observed case of Kimura's disease occurring during hemodialysis, involving the thoracic and abdominal lymph nodes, which spontaneously resolved nearly completely after two months. Early diagnosis and recognition of Kimura's disease may spare both the patient and doctor from the need for unnecessary invasive diagnostic procedures. Therefore, we emphasize that we need to have a high index of suspicion regarding Kimura's disease.
