Striking temporally dynamic ECG changes associated with recurrent chest pain in a case of myopericarditis.

A 33-year-old man without medical history or cardiovascular disease risk factors presented with recurrent progressively worsening chest pain that had been preceded by few days of flu like illness. His initial ECG and troponin rise supported the diagnosis of myopericarditis for which he was treated with aspirin and non-steroidal anti-inflammatory drugs (NSAIDs) with good response initially. He later on developed severe recurrent chest pain and became tachycardic and hypotensive.

Pseudo-dissection of ascending aorta in inferior myocardial infarction.

Acute aortic dissection is a cardiac emergency which can present as inferior myocardial infarction. It has high morbidity and mortality requiring prompt diagnosis and treatment. Rapid advances in non-invasive imaging have facilitated the early diagnosis of this condition and in ruling out this potentially catastrophic illness.

Endocarditis presenting as acute abdomen.

Infective endocarditis remains an interesting and challenging disease in which the presenting features have been modified by medical progress. We report a case of a 63-year-old woman who presented with pyrexia, weight loss, night sweats and fatigue over a period of 7 weeks, at the end of which she developed severe right hypochondrial pain, mimicking acute abdomen. She was provisionally diagnosed with and treated for acute cholecystitis to no avail.

Right atrial mass in the context of recurrent non-Hodgkin's lymphoma: atrial myxoma presenting with atrial flutter.

A case is described of a 57-year-old man with a background of low-grade bronchus-associated lymphoid tissue (BALT) non-Hodgkin's lymphoma presenting with dyspnoea and palpitations. Diagnostic work-up revealed paroxysmal atrial flutter and the presence of a mass in the right lower lobe at bronchoscopy, with histology confirming recurrent BALTOMA. Transthoracic echocardiography (TTE) revealed a mass in the right atrium.

Composite splenic marginal zone lymphoma and classic Hodgkin lymphoma -- an unusual combination.

The simultaneous occurrence of Hodgkin lymphoma with a variety of B-cell Non-Hodgkin lymphomas (composite lymphoma) has been described. We report the first case of composite Hodgkin lymphoma and splenic marginal zone lymphoma occurring simultaneously in the same lymph node of a 64-year-old man who presented with cervical and axillary lymphadenopathy and massive splenomegaly. He had a peripheral blood lymphocytosis and a bone marrow infiltrated by small lymphocytes.
