Diagnosis is often incidental with high index of histopathological suspicion from clinical pathologist. The pathological pattern is quite unique with distinct immunohistochemical stains.

A Giant Right Heart Thrombus-in-Transit: The Challenge of Anticoagulation in Factor V Leiden Thrombophilia.

Factor V Leiden (FVL) is an autosomal dominant condition resulting in thrombophilia. Factor V normally acts as a cofactor for prothrombinase, helping cleave prothrombin to thrombin. A single point mutation in it disrupts factor V, making it unreceptive to protein C and increasing the risk of thrombosis.

Paraspinal and Extensive Epidural Abscess: The Great Masqueraders of Abdominal Pain.

Paraspinal and epidural abscesses are rare conditions often diagnosed later in the disease process that can have significant morbidity and mortality. Predisposing risk factors include diabetes, human immunodeficiency virus, intravenous drug abuse, and previous history of spinal surgery or injection. They can threaten the spinal cord by compressive effect, leading to sensory motor deficits and ultimately paralysis and death.

Lambl's Excrescence Associated with Cryptogenic Stroke: A Case Report and Literature Review.

Background: In 1856, a Bohemian physician, Vilém Dušan Lambl, first described the presence of filiform lesions in aortic valve leaflets. Lambl's excrescences are tiny filiform strands that arise on the line of valve closure, and result from valvular wear and tear. It is a rare cause of cardioembolic stroke that can be detected by transesophageal echocardiogram.
