Centrilobular necrosis occurs.Macroscopically, the liver has a pale and spotty appearance in affected areas, as stasis of the blood causes pericentral hepatocytes (liver cells surrounding the central venule of the liver) to become deoxygenated compared to the relatively better-oxygenated periportal hepatocytes adjacent to the hepatic arterioles. This retardation of the blood also occurs in lung lesions, such as chronic interstitial pneumonia, pleural effusions, and intrathoracic tumors. Diagnosis
It is diagnosed with laboratory testing, including liver function tests, and radiology imaging, including ultrasounds. Treatment
Treatment is directed largely to removing the cause, or, where that is impossible, to modifying effects of the heart failure. Thus, therapy aimed at improving right heart function will also improve congestive hepatopathy. True nutmeg liver is usually secondary to left-sided heart failure, causing congestive right heart failure, so treatment options are limited.Treatments for heart failure include medications, an intra-aortic balloon pump, a ventricular assist device, heart valve replacements, extracorporeal membrane oxygenation (if the heart failure worsens suddenly and especially if an infection was the cause), an artificial heart, or a heart transplant (from a deceased human donor, or from a pig). Some patients may need a liver transplant; an artificial liver can be used for a short period of time (about two weeks or so) as a bridge to a transplant, or until the liver recovers. See also

Pyoderma means any skin disease that is pyogenic (has pus). These include superficial bacterial infections such as impetigo, impetigo contagiosa, ecthyma, folliculitis, Bockharts impetigo, furuncle, carbuncle, tropical ulcer, etc. Autoimmune conditions include pyoderma gangrenosum. Pyoderma affects more than 111 million children worldwide, making it one of the three most common skin disorders in children along with scabies and tinea. See also
