They should not be confused with adrenocortical “nodules”, which are not true neoplasms. Adrenocortical adenomas are uncommon in patients younger than 30 years old, and have equal incidence in medium robbins pathology pdf sexes.

The clinical significance of these neoplasms is twofold. Functional adrenocortical adenomas are surgically curable. Most of the adrenocortical adenomas are less than 2 cm in greatest dimension and less than 50 gram in weight. However, size and weight of the adrenal cortical tumors are no longer considered to be a reliable sign of benignity or malignancy. Grossly, adrenocortical adenomas are encapsulated, well-circumscribed, solitary tumors with solid, homogeneous yellow-cut surface. Necrosis and hemorrhage are rare findings.

Adrenal neuroblastoma typically presents with a rapidly enlarging abdominal mass. Most pheochromocytomas are initially treated with anti-adrenergic drugs to protect against catecholamine overload, with surgery employed to remove the tumor once the patient is medically stable.

In CPAM, usually an entire lobe of lung is replaced by a non-working cystic piece of abnormal lung tissue. This abnormal tissue will never function as normal lung tissue. The underlying cause for CPAM is unknown.

It occurs in approximately 1 in every 30,000 pregnancies. In most cases the outcome of a fetus with CPAM is very good. In rare cases, the cystic mass grows so large as to limit the growth of the surrounding lung and cause pressure against the heart. In these situations, the CPAM can be life-threatening for the fetus. CPAM can be separated into five types, based on clinical and pathologic features. Three quarters of affected patients are asymptomatic.
