What causes Peliosis Hepatis?

The cause is probably damage to the sinusoidal lining cells. Peliosis hepatis is associated with use of hormones (eg, anabolic steroids, oral contraceptives, glucocorticoids), tamoxifen, vinyl chloride, vitamin A, and, particularly in kidney transplant recipients, azathioprine.

What is liver peliosis?

INTRODUCTION. Peliosis hepatis is a rare vascular condition of the liver characterized by a proliferation of the sinusoidal hepatic capillaries that results in cystic blood-filled cavities distributed randomly throughout the liver [1,2].

What is bacillary Peliosis?

HIV-associated bacillary peliosis hepatis is an unusual, treatable opportunistic infection, probably caused by the same organism that causes cutaneous bacillary angiomatosis. Our failure to find bacilli in non-HIV-associated cases implies that other pathogenetic mechanisms may also be responsible for peliosis hepatis.

What is enhancing lesion liver?

Benign Arterial Phase–enhancing Lesions Hepatic adenoma is a focal benign proliferation of hepatocytes within an otherwise normal liver. These lesions most often occur in young women who have used oral contraceptives. In some cases, the lesions regress after oral contraceptives are discontinued.

Is Peliosis Hepatis curable?

No specific treatment for peliosis hepatis is known. Several treatments for peliosis hepatis have been reported, such as partial hepatectomy,16 liver transplantation,17 and transhepatic artery embolization.

What does Peliosis mean?

Definitions of peliosis. any of several blood diseases causing subcutaneous bleeding. synonyms: purpura. types: nonthrombocytopenic purpura. purpura resulting from a defect in the capillaries caused by bacteria or drugs.

Is bacillary angiomatosis painful?

Bone pain, frequently in the forearms or legs, can also occur. Visceral involvement associated with bacillary angiomatosis may be asymptomatic or may cause the following symptoms: Fever, chills, malaise, night sweats, anorexia, and weight loss. Symptoms of peliosis hepatis: Abdominal pain, nausea, and vomiting.

How do you get bacillary angiomatosis?

Bacillary angiomatosis (epithelioid angiomatosis) is an uncommon disease characterized by neovascular proliferation in the skin or the internal organs (peliosis) due to an infection with Bartonella henselae or Bartonella quintana. It commonly occurs in immunocompromised as well as immunocompetent patients.

Is bacillary angiomatosis benign?

Bacillary angiomatosis (BA), a benign vascular proliferation in skin and visceral organs, has been identified as a response to infection by the Bartonella species of bacteria.
