We have encountered 11 cases of Kimura disease, comprising 10 males and 1 female. The ages at presentation ranged from 16 to 48 years, with a mean of 31.5 years. The sites of the subcutaneous masses were bilateral posterior auricular regions in two cases, frontal region in two cases, temporal region in two cases, head region in one case, parotid region in two cases, parotid and temporal regions in one case, and left earlobe in one case. The interval from onset to surgery ranged from 1 to 10 years, with a mean of 4.7 years.For diagnostic imaging, a combination of magnetic resonance imaging (MRI) and ultrasonography had a high diagnostic value. MRI depicted abnormalities at sites in contact with bone, such as posterior auricular regions, and sites with abundant soft tissue, such as parotid and cheek regions. Diffuse atrophy of subcutaneous fat was observed at the sites of the masses. On ultrasonography, the interior of lymph nodes was homogeneous and hyperechoic, whereas the periphery was hyperechoic, and blood vessels entering lymph nodes were clearly depicted.Surgery was performed in all cases. Postoperative adjuvant radiotherapy was conducted in one patient and radiotherapy and steroid therapy in one other patient. There were two relapses, and both were excised by repeated surgery. Surgical excision of the subcutaneous mass in Kimura disease has the advantages that the treatment period is short and precise histopathologic diagnosis can be obtained.

Kimura's disease: case report and review of the literature.J Thorac Imaging. 2005 Nov;20(4):298-300.

Kimura's disease is a rare, chronic inflammatory disease characterized by subcutaneous nodules in the head and neck regions associated with regional cervical lymphadenopathy. Following its recognition as a pathologic entity, numerous reports have been published detailing the pathogenesis, radiologic manifestations, and treatment modalities. An extensive review of the literature did not reveal any cases of diffuse thoraco-abdominal lymphadenopathy described in relation to Kimura's disease. Hence, the interest in the case discussed here.
