Eosinophil-rich Variant of Follicular Dendritic Sarcoma of Cervical Lymph Node: An Extremely Rare Entity

Follicular dendritic cell neoplasms are extremely rare. Information regarding the accurate treatment and prognosis is limited owing to their rarity; thus, this tumor encompasses a domain to be brought into focus. Clinical and pathological diagnoses warrant a high index of suspicion as this entity is not considered in routine clinical practice. Histopathologically it mimics various other neoplasms which lead to higher chances of misdiagnosis at initial evaluation. Use of follicular dendritic cell immunohistochemical markers CD ۲۱ and CD ۳۵ helps in rendering a definitive diagnosis.
