Mediastinal Cartilaginous Hamartoma

Pulmonary hamartoma (the cartilaginous type).

Isolated chylopericardium due to mediastinal lymphangiomatous hamartoma;.

Isolated chylopericardium is a rare cause of pericardial effusion. Intrapericardial chyle was first noticed by Hasebroek (1888) at necropsy. Twenty years ago Groves and Effler (1954) first reported a clinical case of isolated chylopericardium. The present case is similar to theirs in several respects, and is the nineteenth case to be reported. To our knowledge this is the first British report o...

Vascular and cartilaginous hamartoma (mesenchymoma) of the ribs in infancy.

Vascular and cartilaginous hamartoma of chest wall, also known as mesenchymoma, is a very rare condition which arises exclusively in the chest wall of infants. Less than 20 cases have been reported. Its importance lies in the fact that sometimes it is mistaken radiologically and histologically for a malignant tumour. It is not only benign but also self limiting and its recognition is important ...

Esophageal stricture caused by a mediastinal hamartoma invading the esophageal wall.

A 60-year-old man presented with dysphagia, which had persisted for 2 months. A barium meal test revealed a stricture in the upper esophagus, and smoothmucosa at the narrow segment of the esophagus (●" Fig.1). He subsequently underwent endoscopy. Endoscopic examination revealed a mucosal bulge in the esophagus at a distance of 18–24cm from the incisors, extending to about half of the esophageal...

Myelin in cartilaginous fish

Myelin is probably one of the most fascinating and innovative biological acquisition: a glia plasma membrane tightly wrapped around an axon and insulating it. Chondrichthyans (cartilaginous fishes) form a large group of vertebrates, and they are among oldest extant jawed vertebrate lineage. It has been known from studies 150 years ago, that they are positioned at the root of the successful appe...
