Definition of telangiosis

tel-angi--osis - abnormal capillary condition (abnormality in the ends of blood vessels). telangiosis describes pathological changes in capillaries and terminal arterioles, the smallest branches of the vascular system. It differs from telangiectasia (dilated vessels) by implying a broader disease process rather than just dilation; it’s rarely used clinically but appears in pathology contexts for microvascular disorders.


Etymology of telangiosis

The etymology of “telangiosis” is derived from the components “tel- + angi-+ -osis,” indicating its association with blood vessels.

  • tel(o)- or tel-: greek télos (τέλος), meaning “end” or “terminal.”
  • angi(o)-: Greek angeîon (ἀγγεῖον), meaning “vessel” (as in prior angi- terms).
  • -osis: Greek suffix indicating “condition,” “disease,” or “abnormal process.”
  • Literally “disease of the end-vessels,” referring to capillaries.
