Castleman Disease Presenting in the Neck: A Report of 3 Cases and a Literature Review.

Abstract

BACKGROUND Castleman's disease (CD) is a reactive lymph node hyperplasia initially identified by Castleman in 1956. CD predominantly affects individuals 20-50 years of age, with low incidence in children. This case report describes 3 cases of CD treated in our hospital and reviews the relevant literature. The purpose of this case report was to enhance clinical understanding and treatment of CD in the head and neck in children. CASE REPORT To enhance clinical understanding and improve treatment of CD in the head and neck region in children, we present the cases of 3 patients who were admitted to the hospital, primarily presenting with a neck mass. Preoperatively, the patients collectively exhibited non-specific findings. Surgical interventions were performed with Cases 1 and 3 undergoing left functional (radical) neck lymph node dissection, in contrast to Case 2, in which bilateral functional (radical) neck lymph node dissection was executed. Pathological examination confirmed the diagnosis of CD in each of the 3 patients. Following surgery, a follow-up period ranging from 3 months to 1 year revealed that all patients had successfully recovered, with no recurrence. CONCLUSIONS Castleman disease is a rare disease in children and difficult clinical diagnosis. Some patients with unicentric Castleman disease (UCD) can be treated with surgery, and those with multicentric Castleman disease (MCD) need chemotherapy, but at present there is no widely accepted treatment plan.
