Livedo reticularis is a common skin finding consisting of a mottled reticulated vascular pattern that appears as a lace-like purplish discoloration of the skin. [1] The discoloration is caused by reduction in blood flow through the arterioles that supply the cutaneous capillaries, resulting in deoxygenated blood showing as blue discoloration ().

If the part of the brain that interprets these input signals is damaged, then a distorted output is possible.

Since its initial description, the spectrum of diseases caused by A. haemolyticum has been expanded to include sepsis and osteomyelitis. [6] Organisms are Gram-positive, facultative anaerobic , catalase -negative rods (but transition to the coccal shape occurs as the organism grows) with arrangements described as matchbox or Chinese letters ...
