Metachronous Bilateral Adrenal Neuroblastoma: A Case Report and Literature Review.

Abstract

A baby presented with a large right adrenal mass, multiple hepatic lesions and diffuse bone marrow infiltration when she was just over 1 month old. After needle biopsy and a histologic definition of neuroblastoma, she underwent chemotherapy and a subsequent complete resection. Three years after diagnosis, a large left adrenal localized mass was detected. The patient underwent complete surgical excision, and a diagnosis of poorly differentiated neuroblastoma with multiple lymph nodes involvement was defined. Adjuvant chemotherapy was initiated. To our knowledge, it is the first case report of metachronous bilateral adrenal neuroblastomas harboring completely different genetic expression profiles.
