Neuroblastoma
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 commonest childhood tumor after leukemia and b...

Adrenal lesions (differential)
Adrenal lesions cover a broad spectrum from benign to neoplastic entities. Due to increased use of cross-sectional imaging they are frequently detected as incidental lesions (incidentalomas). If found incidentally, please refer to the Management of Incidental Adrenal Masses: American College of ...

Neuroblastoma vs Wilms tumor
Both neuroblastoma and Wilms tumor occur in early childhood and typically present as large abdominal masses closely related to the kidneys. Distinguishing between the two is important, and a number of features are helpful.

Congenital neuroblastoma is defined as neuroblastoma identified within a month of birth, and is divided into:
fetal neuroblastoma
neonatal neuroblastoma
In most cases they present as stage 1, 2 or 4S (see neuroblastoma staging).
Fetal neuroblastoma
In 90% of cases, fetal neuroblastomas aris...

Pheochromocytoma
Pheochromocytomas are an uncommon tumor of the adrenal gland, with characteristic clinical, and to a lesser degree, imaging features. The tumors are said to follow a 10% rule:
~10% are extra-adrenal
~10% are bilateral
~10% are malignant
~10% are found in children
~10% are not associated wit...

Primary adrenal cortical carcinoma (also known as adrenocortical carcinoma) is a highly malignant but rare neoplasm. It may present as a hormonally active or inactive tumor.
Epidemiology
Although men and women are affected equally, functioning tumors are more common in females, who are also m...

Primary pigmented nodular adrenal dysplasia
Primary pigmented nodular adrenal dysplasia (PPNAD) is a rare benign adrenal condition characterized by ACTH-independent autonomous hypersecretion of cortisol, leading to Cushing syndrome.
Epidemiology
PPNAD is often familial. Patients typically present as children or young adults, and there ...

Adrenal hemangioma
Adrenal hemangiomas are rare benign tumors that are usually incidentally identified (one example of an adrenal incidentaloma). Its significance mainly relates to the difficulty in differentiation from other malignant lesions.
Epidemiology
Although these can be found at any age, they are most ...
Article
Adrenal gland
The adrenal (suprarenal) glands (often shortened to just the adrenals) are paired organs of the endocrine system, often asymmetric in shape.
Gross anatomy
The adrenal glands are located superior and anteromedial to the kidneys, within the perirenal space, and enclosed by perirenal fascia. Eac...
