Sumario:Kimuras disease is a chronic inflammatory disorder of unknown etiology. It is rare in the West, but endemic in Asia. It typically presents as solitary or multiple subcutaneous nodules, that slowly increase in size. The lesions are variably painful and pruritic. It often accompanied by regional lymphadenopathy, raised serum eosinophil counts, and markedly elevated serum immunoglobulin E levels. Histologically, the lesions are characterized by reactive lymphoid follicles with eosinophilic infiltration and an increased amount of postcapillary venules. The optimal treatment for KD remains controversial. Although the condition seldom resolves spontaneously, malignant transformation has not been reported to date, and the prognosis is good. We describe a male patient with a 4-year pruritic progressive “bump” in front of his left ear. On physical examination, the patient had 2 discrete lesions on the left side of his face near his ear. Postauricularly, there was a 3 × 5 cm erythematous to violaceous, indurated nodule. Preauricularly, there was a similar, but smaller cyst-like nodule. Punch biopsy showed a superficial and deep nodular and interstitial infiltrate, reactive lymphoid follicles with a dense infiltration of eosinophils and areas of eosinophilic follicle lysis. The patient received intralesional triamcinolone acetonide injections 10 mg/cc behind left ear with a good improvement.
