Kimura's disease affecting multiple body parts in a 57-year-old female patient: a case report

Kimura's disease (KD) is a rare chronic inflammatory disease with unknown etiology. It usually manifests as a painless soft tissue mass or subcutaneous nodule on one side of the patient's head and/or neck and rarely affects multiple parts of the body. The disease is more common among young Asian males.

A 57-year-old Chinese woman complained of multiple masses on her body surface. Ultrasonography was used to examine the retroperitoneal, bilateral neck, bilateral supraclavicular, bilateral axillary, and bilateral inguinal superficial lymph nodes. Enlargement of multiple lymph nodes was found in all areas. Many solid nodules were also found in the right parotid gland and right posterior neck area, respectively. Numerous solid nodules were seen on the left chest wall. Laboratory tests showed that the percentage of eosinophils in the whole blood was 39.40%, total immunoglobulin E (IgE) level was > 5000 kU/L, and serum special IgE to Phadiatop (inhaled allergens) and fx5 (food allergens) were 1.01 and 1.04 kUA/L, respectively. After a complete examination, the masses located in the right neck, retroauricular and left axillary regions, and left chest wall were resected directly. Postoperative pathological findings revealed KD.

The case discussed in this study is extremely rare and did not meet the common affected areas and age characteristics of KD. This presentation can be used to improve disease awareness among physicians.
