Adrenal ganglioneuroma with retroperitoneal lymph node metastasis: A rare scenario.

Abstract: Ganglioneuroma (GN) is the most differentiated and benign variant of neuroblastic tumors, most commonly located in the posterior mediastinum, followed by the retroperitoneum and adrenal gland. Children of <10 years of age are more commonly affected than adults. Though benign, GNs can very rarely metastasize to regional lymph nodes or distant sites like liver, bone, spleen, and soft tissues. Metastatic lesions are assumed to represent neuroblastomas in which the metastasis and the primary tumor, both have matured. This differentiation can occur spontaneously or after treatment. We present a primary ganglioneuroma of adrenal gland in a 4-year-old child with nodal metastasis, without any blastemal component at any site.
