NAIL-FOLD CAPILLARIES IN CONNECTIVE-TISSUE DISORDERS

Abstract
Nail-fold petechiæ are well known in cases of connective-tissue disorders. By means of reflected light microscopy and photomicrography it is possible to recognise a stage before hæmorrhage occurs from the nail-fold capillaries, when these are only dilated; recognition of this feature and careful measurement of the capillary diameters would assist in supporting a diagnosis.
