摘要:

Summary1Five cases of adenochondroma of the lung are reported. Two were discovered during routine X‐ray examination and removed surgically. Three were chance findings at autopsy. None had caused symptoms. All were histologically benign.2The reasons for using the name “adenochondroma” are disc

摘要:

SummaryThe clinical features of many apparently widely differing syndromes may be explained on common grounds. It is not suggested that they have a common cause. The vascular malformation of the retina present in Von Hippel's disease is responsible for changes in the fundus which resembles those seen in Coate's disease. In early childhood they lead to the so‐called infantile form of that disease and, in infancy, to one of the forms of pseudo‐glioma.When the inflammation involves the ciliary body and iris, the picture of a chronic cyclitis with the formation of a membrane, and its harmful effect on the lens, is superadded. This is the picture which is seen to appear in the premature infant born with a normal fundus and which gradually develops a “retro‐lental fibroplasia.” Retrolental fibroplasia is a retinitis associated with an irido‐cyclitis occurring in the i

摘要:

SummaryTumours and cysts of the pituitary region may be simple or complex in form.The complex structures, usually para pituitary in position are commonly regarded as having an origin directly from such archaic structures as the hypophyseal duct or less clearly recognizable “cell residues.”The assumption that such tumours or cysts arise from special tissues is due to the view that only these possess the potentialities for production of several tissues and that such capacity is not present in more adult structures.This assumption is misleading on two accounts: (i) the cysts and tumours are not in reality as complex as cursory examination would suggest, and (ii) investigation shows that powers of differentiation greater than those previously recognized are, in effect. present in adult tissues.The various tissues that are seen in these complex structures develop by changes in cells previously present; thus, the cyst or tumour does not arise like Minerva, fully panoplied, from the brow of Jove but develops by gradual differentiation of proliferating cells in the same manner as is seen in the formation of normal tissues or organs.In a cyst, for example, there first appears a simple epithelium which may be in part ciliated; this may become pseudostratified or stratified (the former may be ciliated and the second may show keratin formation). The squamous epithelium may then form a basal‐type epithelium with calcifiable homogeneous secretion. Lymphocytic accumulation and cartilage formation occurs and, in areas of excessive keratinous formation, cholesterol accumulation may be found. When all these various tissues and materials are found together the structure becomes one of considerable macroscopical and histological complexity.The close relation of such complex tumours and cysts to simple ones is thus clear and it is unnecessary to regard the essential progenitor of such structures as a “totipotent” cell or a cell of some special kind. The complex cyst or tumour is merely a variant of that which, because it closely resembles the tissues commonly observed in the part, is usually regarded

摘要:

SummaryTotal removal of the prostate and seminal vesicles by Millin's retro‐pubic approach was carried out on forty‐seven cases with a mortality Of four cases, and few complications. The technique is described. The total removal of the prostate has special advantages over enucleation. Its scope in the treatment of carcinoma should be fully explo
