Castleman's Disease as a Rare Differential Diagnosis of Lymphadenopathy: 2 Case Reports and Review of Literature

Abstract

ntroduction: Lymphadenopathy is a common complaint in children. It's defined as abnormality in size or character of lymph node. It may be localized or generalized. It may be part of a group of signs and symptoms or the sole finding and chief complaint. Several reasons can lead to Lymphadenopathy. Castleman's disease is a rare differential diagnosis of generalized or localized Lymphadenopathy. It's a rare lymph proliferative disorder that rarely occurs in children. Case presentation: We reported two cases, the first one was 13 years old female with multicenteric castleman's disease associated with constitutional manifestations and unusual hyaline vascular pathology successfully treated with monthly combination chemotherapy, the second one was 2.5 years old male with unicentric hyaline vascular castleman's disease with unusual young age at presentation successfully treated with surgical excision. Conclusion: Castleman's disease is a rare cause of Lymphadenopathy. Although, it's rare in children, it can occur at any age. Most of cases of multicenteric castleman's disease are plasma cell variant, yet hyaline vascular type may occur. Multicenteric castleman's disease can be successfully treated with monthly combination chemotherapy. Most cases of unicentric castleman's disease are hyaline vascular type. Although, surgical removal of unicentric type is usually sufficient to achieve complete remission, recurrence can still occur.
