AIMS To review 25 cases of breast hamartoma and discuss the pathological criteria, and the usefulness of imaging modalities, fine needle aspiration cytology (FNAC), and needle core biopsy in the diagnosis. METHODS The hamartomas were assessed for interlobular fibrotic stroma, stromal adipose tissue content, pseudo-angiomatous stromal hyperplasia, and epithelial changes (hyperplasia, adenosis ...
We present a rare case of congenital cystic adenomatoid malformation (CCAM) type III (mycrocystic) in young, 19 years old primigravida. Diagnosis has been accomplished by ultrasound examination in 26th week of gestation. Hyperechogenic, mycrocystic mass was found in left pulmonary lobe with contra lateral displacement of mediastinum, hypoplasia of the right lung and extensive polyhydramnios. Pr...
Fetal lung masses are rare findings in prenatal ultrasound scanning in general population, of which congenital cystic adenomatoid malformation is the most commonly diagnosed type. This paper reports a single case of congenital cystic adenomatoid malformation detected at our hospital and the subsequent clinical follow-up using ultrasound scanning and fetal magnetic resonance imaging.
The respiratory tract contains numerous peptides secreted from special pulmonary epithelial cells whichare called endocrine cells. The function of neuroendocrine cells is modulated by amines. Serotonin has strong vasomotor and bronchomotor effects in the airway mucosa. The objective of this study was to determine presence and distribution of serotonin-positive endocrine cells in respiratory tra...
Congenital cystic adenomatoid malformation of the lung is a developmental abnormality characterized by abnormal proliferation of terminal bronchioles forming cysts of varying sizes. Extensive lesions are associated with a poor prognosis due to the development of nonimmune hydrops and/or pulmonary hypoplasia. The advent of high-resolution ultrasonography has made it possible to identify these le...
Congenital cystic adenomatoid malformation of the lung is a rare disease that shows multiple cystic lesions in pulmonary tissues in the development process. It was first described by Chin et al.1 in 1949 and its incidence is known to be 1:25,000 to 1:35,0002. With the development of prenatal diagnosis, this disease can be diagnosed in 60% and detected within 2 years because of such symptoms as ...
Interstitial pulmonary emphysema is a well-documented complication of assisted mechanical ventilation in premature infants with respiratory distress syndrome. Localized persistent interstitial pulmonary emphysema (LPIPE) confined to a single lobe was incidentally presented in a 4-day-old female infant. This patient was a normal full-term baby with no respiratory distress symptom and no experien...
Diagnosis of congenital cystic adenomatoid malformation of the lung in newborn infants and children.
Seventeen patients were diagnosed as having congenital cystic adenomatoid malformation of the lung during 1970-88. One case was associated with congenital diaphragmatic hernia and the child died before operation. The other 16 children underwent successful surgery. The patients presented in one of three ways--with neonatal respiratory impairment (12 cases) requiring urgent diagnosis and treatmen...
Adenomatoid odontogenic tumor (AOT) is an uncommon benign odontogenic lesion that affects young patients, with female predominance, mainly in second decade, showing a radiolucent unilocular image associated with an unerupted tooth, usually a canine. In spite of previous and confusing denominations, such as adenoameloblastoma or adenomatoid ameloblastic tumor, AOT is a benign tumor with a very l...
The Smith-Lemli-Opitz syndrome (SLOS) is an autosomal recessive multiple congenital malformation syndrome caused by dehydrocholesterol reductase deficiency. The diagnosis is confirmed by high 7- and secondarily 8-dehydrocholesterol levels in plasma and tissues and/or by detection of biallelic mutations in the DHCR7 gene. The phenotypic spectrum of SLOS is broad, ranging from a mild phenotype co...
