Kikuchi's disease: a Singapore case series.

INTRODUCTION: Kikuchi's disease is a benign form of cervical lymphadenopathy that commonly affects young adults. We report a case series from our hospital.

METHODS: The clinical features of 23 cases of Kikuchi's disease diagnosed at Changi General Hospital over a seven year period are presented. The cases were identified from pathology records using the search term histiocytic necrotising lymphadenitis.

RESULTS: Most of our patients (78 percent) were young women who presented with cervical lymphadenopathy. The median age was 31 years. In the 18 cases who completed follow-up at the hospital, there was spontaneous resolution of symptoms within a six-month period. One patient demonstrated seropositivity for systemic lupus erythematosus (SLE) and was initially started on steroids. However, the treatment was discontinued shortly afterwards since she did not meet the diagnostic criteria for SLE. Excision biopsy of the affected lymph node was the diagnostic method of choice.

CONCLUSION: Kikuchi's disease is not uncommon in the Singaporean population. Establishing an early diagnosis is crucial since the clinical presentation can mimic tuberculous lymphadenitis or malignant lymphoma. The diagnostic method of choice is excision biopsy.
