An "Orthrius-group" of genera is proposed, and defined to include Aphelochroa Quedenfeldt, 1885; Caridopus Schenkling, 1908; Dozocolletus Chevrolat, 1842; Gyponyx Gorham, 1883; Languropilus Pic, 1940; Orthrius Gorham, 1876; Pieleus Pic, 1940; Xenorthrius Gorham, 1892; plus three new genera Neorthriusgen. n., Nonalatusgen. n. and Pseudoastigmusgen. n. A phylogeny of the 11 constituent Orthrius-g...

Vanishing bone disease, also known as idiopathic osteolysis and Gorham Stout disease is a rare clinicopathological entity characterized by proliferation of intra osseous capillaries and lymphatics thereby leading to bony destruction. All age groups can be affected. The most common sites for predilection are the shoulder and pelvis. The authors report a rare and interesting case of idiopathic os...

A 7-year-old girl with a history of headaches and Gorham disease was surgically treated in infancy for Chiari I malformation. Subsequent investigation revealed that her cerebellar tonsillar ectopia was due to a long-standing spinal CSF-lymphatic fistula causing intracranial hypotension. Percutaneous fistula closure was performed several times, resulting in transient symptomatic improvement.

Gorham syndrome is a rare disease that presents as progressive osteolysis, and may affect any part of the skeleton. The pathologic process involves the replacement of normal bone by aggressively expanding but non-neoplastic vascular tissue, resulting in massive osteolysis of the adjacent bone. If the spine and ribs are affected, the subsequent kyphosis and chest wall deformity may cause severe ...
