Congenital adrenal tissue in the lung with adrenal cytomegaly. Case report and review of the literature.

Adrenal cytomegaly is a cellular abnormality found in the fetal and neonatal adrenal gland. It is characterized by large polyhedral cells with granular eosinophilic cytoplasm and irregular pleomorphic nuclei. A case of bilateral adrenal cytomegaly in five-day-old infant with two foci of pulmonary involvement is reported with a review of the literature. The question of whether the pulmonary lesion represents metastasis or cytomegalic change in ectopic adrenal tissue is discussed.
