I Hereditary hemorrhagic telangectasia (HHT) or Rendu-Osler-Weber syndrome is characterized for fibromuscular dysplasia of the terminals vessels that propitiate the development of vascular ectasias and arteriovenous malformations. The mucosae, skin, lung and brain are the most commonly affected organs. This article describes a case of HHT an adult patient associated with multiple angiodysplasic...

Vascular anomalies are a diverse group of related conditions that include vascular tumors (hemangiomas) and vascular malformations (capillary malformations, venous malformations, lymphatic malformations and arteriovenous malformations). In the past decade or so, research has revealed the genetic or molecular basis for some of these lesions. We now know that a number of hereditary vascular malfo...

Bronchogenic cysts are congenital foregut malformations thought to develop due to abnormal budding of tracheal diverticulumand proximal bronchial structures during embryologic development. The cyst is lined by ciliated pseudostratified columnar epithelium and the wall contains cartilage and layers of smooth muscle. These lesions most commonly are seen in the mediastinum, lung, or pleural spaces...

Hereditary hemorrhagic telangiectasia (HHT) is a dominantly inherited genetic vascular disorder with an estimated prevalence of 1 in 6,000, characterized by recurrent epistaxis, cutaneous telangiectasia, and arteriovenous malformations (AVMs) that affect many organs including the lungs, gastrointestinal tract, liver, and brain. Its diagnosis is based on the Curaçao criteria, and is considered d...

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...

Chromosomal aberration leading to congenital malformations is an important cause for infant mortality. Forty five infants with congenital malformations affecting various systems were screened by photokaryotyping for evidence of cytogenetic abnormalities after taking thorough family and obstetric history. Among the cases multiple malformations suggestive of Down’s Syndrome was the commonest. The...
