• Angiectasia — An abnormal, permanent, and pathological dilation of a blood vessel or a lymphatic vessel, occurring either as a congenital anomaly or due to the loss of vascular wall elasticity under the influence of inflammatory or mechanical factors. In clinical and histopathological contexts, this structural phenomenon affects capillaries, venules, or small lymphatic vessels, being visible under the microscope as widened vascular channels that can predispose to local bleeding or circulatory stasis.
