Congenital cystic adenomatoid malformation (CCAM) is a rare bronchopulmonary malformation characterized by loss of the normal pulmonary tissue. CCAM may be frequently associated with cardiac and renal anomalies. Rarely, CCAM may be seen with chromosome abnormalities. This is the first reported neonatal case of prenatally detected CCAM and postnatally diagnosed trisomy 13.

BACKGROUND Type I pleuropulmonary blastoma (PPB) and congenital cystic adenomatoid malformation of the lung (CCAM) are cystic lung diseases of childhood. Their clinical and radiological presentations are often similar, and pathologic discrimination remains difficult in many cases. As a consequence, type I PPB and CCAM are frequently confused, leading to delayed adequate management for type I PP...

Congenital cystic adenomatoid malformation of the lung (CCAM) is a rare congenital lesion whose pathogenesis is not well defined. It is generally accepted that the various types of CCAMs originate at different levels of the tracheobronchial tree. To further define the pathogenesis of CCAM, we evaluated the cellular composition of different CCAM types by immunohistochemistry. Twenty-two CCAMs (1...

BACKGROUND CCAM is a French terminology for coding clinical procedures. CCAM is a multi-hierarchical structured classification for procedures used in France for reimbursement in health care, which is external to UMLS. OBJECTIVE The objective of this work is to describe a French lexical approach allowing mapping CCAM procedures to the UMLS Metathesaurus to achieve interoperability to multiple ...

The understanding of pathological processes is based on the comparison between physiological and pathological conditions, and transcriptomic analysis has been extensively applied to various diseases for this purpose. However, the way in which the transcriptomic data of pathological cells relate to the transcriptomes of normal cellular counterparts has not been fully explored, and may provide ne...

Congenital cystic adenomatoid malformation (CCAM) and bronchopulmonary sequestration are congenital lung lesions. They are classified as separate entities. Each of them has distinct embryology, pathology, and natural history. However there are some commonalities between them. CCAM may have a pulmonary artery supply, or be supplied like a sequestration from the aorta, and histological features o...

Congenital cystic adenomatoid malformation (CCAM) of the lung is a rare hamartomatous cystic lesion, characterized by the presence of large cysts, which are histopathologically lined by pseudostratified ciliated cells. It has been recognized that rare cases of type 1 CCAM show malignant transformation, usually bronchioloalveolar carcinoma (BAC) or adenocarcinoma. Herein, we describe a case of B...

BACKGROUND Congenital cystic adenomatoid malformation (CCAM) is mostly reported from the second trimester of pregnancy. We report a case of a microcystic type of CCAM that was suggested by routine ultrasound examination at a gestational age of 12 weeks. CASE REPORT First-trimester ultrasound screening revealed the presence of a hyperechoic image that occupied the whole of the right lung, withou...

In many organs, integrins and cadherins are partly regulated by Hox genes, but their interactions in airway morphogenesis and congenital lung diseases are unknown. We previously showed that the Hox protein HoxB5 is abnormally increased in bronchopulmonary sequestration (BPS) and congenital cystic adenomatoid malformation (CCAM), congenital lung lesions with abnormal airway branching. We now rep...

UNLABELLED Congenital cystic adenomatoid malformation (CCAM) is an uncommon, nonhereditary anomaly caused by arrest of lung. Patients with CCAM may present with respiratory distress as newborns, or may remain asymptomatic until later in life. CCAM type I is rarely found in association with bronchial atresia (BA) in adults; we present such a case. CASE A 54-year-old female presented with chron...
