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.

How can you tell the difference between Kaposi sarcoma and bacillary angiomatosis?

Bacillary angiomatosis lesions typically possess capillary proliferation and neutrophilic inflammation. In contrast, Kaposi sarcoma lesions display slitlike vascular spaces containing lymphoplasmacytic infiltrates. A skin biopsy is required to establish diagnosis.

What is Peliosis of the liver?

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].

How is bacillary angiomatosis diagnosed?

When a cutaneous nodule is present, a biopsy is ideal to diagnose bacillary angiomatosis. Work up to exclude peliosis of the liver and spleen should be done. Further evaluation can be done based on the associated symptoms and physical exam.

How do you treat angiomas?

There are three common ways to remove angiomas. Electrodesiccation uses an electric needle to destroy the blood vessels in the growth. Cryosurgery involves using liquid nitrogen to freeze away the damaged cells. Finally, laser treatment uses a beam of intense, focused light to remove the growth.

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 an angioma a tumor?

Angiomas are benign tumors derived from cells of the vascular or lymphatic vessel walls (endothelium) or derived from cells of the tissues surrounding these vessels. Angiomas are a frequent occurrence as patients age, but they might be an indicator of systemic problems such as liver disease.

How is angioma treated?

What medical conditions cause angiomas?

Chemicals and compounds that have been reported to cause cherry angiomas include mustard gas, 2-butoxyethanol, bromides, and cyclosporine. Cutaneous angiomas can be skin findings in the POEMS (Polyneuropathy, Organomegaly, Endocrinopathies, M-protein, and Skin changes) syndrome.

What are angiomas caused by?

The exact cause of red moles is unknown, but there may be a genetic factor that makes certain people more likely to get them. They’ve also been linked to pregnancy, exposure to chemicals, certain medical conditions, and climate. There also appears to be a link between cherry angiomas and age.

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.
