2016年8月24日 · A unique pathologic variant that occurs in the perinatal period is called cystic neuroblastoma, which is characterized by one or more macroscopic or microscopic cysts within the tumor. This cystic variant is thought to be a form of neuroblastoma in situ or to result from hemorrhage and necrosis of an existing tumor . According to results of ...

2022年11月4日 · Neuroblastoma is a cancer that develops from immature nerve cells found in several areas of the body. Neuroblastoma most commonly arises in and around the adrenal glands, which have similar origins to nerve cells and sit atop the kidneys.

Cystic neuroblastoma. About 25% of reported neuroblastomas diagnosed in the fetus and neonate are cystic. Patients with cystic neuroblastomas have tumors with lower disease stages and a higher incidence of favorable biology.

2024年8月24日 · Neuroblastomas are tumors of neuroblastic origin. Although they may occur anywhere along the sympathetic chain, the vast majority arise from the adrenal gland. They represent the most common extracranial solid childhood malignancy and are the third most common childhood tumor after leukemia and brain malignancies.

2013年8月18日 · Haemorrhage and necrosis are often seen in neuroblastomas, but cystic neuroblastoma (CN) is a very rare form [1-4]. The content of cysts is usually haemorrhagic, although it may be serous or gelatinous [2, 5]. The usual appearance of an adrenal CN is that of a complex cystic mass compressing or displacing the kidney inferiorly and laterally [3].

Treatment can include chemotherapy, surgery and radiation. The outlook varies depending on the stage of the disease, the child’s age and the risk category.

In contrast to solid neuroblastoma, cystic neuroblastoma has a benign course. Cystic neuroblastoma is diagnosed earlier than solid neuroblastoma, and the former rarely presents with metastatic lesions. All previous reported cases of cystic neuroblastoma were …

Nearly one-half of congenital adrenal neuroblastomas are cystic, and these tumors have clinical and laboratory features that distinguish them from noncystic congenital adrenal neuroblastoma. Diagnostic tests, including CT, MRI, and assessment of tumor markers, have low diagnostic value in the evalua …

Cystic neuroblastoma (CN) is an unusual variant of neuroblastoma characterized by a grossly visible cyst(s) and almost always distinctive microcysts on light microscopy. Rarely, CN will appear solid grossly, but microcystification will be present.

2020年2月22日 · Neuroblastoma (NB) is the most common solid tumor seen in children under two years old. It has both solid and cystic forms. It generally involves the adrenal gland unilaterally. Only 10% of the NBs are as seen bilateral. Both bilateral and cystic forms of NB are a …
