AIDS and non-Hodgkin's lymphoma: initial cardiac manifestations of highly malignant B-cell lymphoma 18 years after HIV infection

Abstract

A 35-year-old man who, as a result of intravenous drug abuse, had become infected with HIV 18 years previously, was admitted with signs of right-heart failure. Three months earlier a systolic murmur had first been heard in the 5th intercostal space parasternally. Transesophageal echocardiography (TEE) demonstrated a 3 x 2 cm right atrial tumour, moderate to severe tricuspid regurgitation and pulmonary hypertension. Blood cultures grew Streptococcus. Endocarditis with atrial thrombi and recurrent pulmonary emboli was diagnosed and treated with antibiotics and anticoagulants. Three weeks later the TEE showed an increase in the atrial tumour. Computed tomography of skull, thorax and abdomen did not demonstrate any significantly enlarged lymph nodes. Exploratory thoracotomy revealed an infiltrating highly malignant centroblastic non-Hodgkin's lymphoma (NHL) of almost the entire free wall of the right atrium. After two courses of chemotherapy (CHOP protocol) the size of the tumour had significantly decreased. The differential diagnosis of a right atrial tumour can be difficult in patients with HIV or AIDS. Even if the site is atypical and there is no lymphadenopathy, a lymphoma should be considered. In case of doubt a histological d...Continue Reading

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Antifungals

An antifungal, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis, cryptococcal meningitis, and others. Discover the latest research on antifungals here.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

B-Cell Lymphoma

B-cell lymphomas include lymphomas that affect B cells. This subtype of cancer accounts for over 80% of non-Hodgkin lymphomas in the US. Here is the latest research.

Antifungals (ASM)

An antifungal, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis, cryptococcal meningitis, and others. Discover the latest research on antifungals here.
