Abstract:
Intravascular leiomyomatosis is a rare condition characterized by histologically benign smooth muscle cell growth within the uterine veins and inferior vena cava and, rarely, into the right chambers of the heart. A 39-year-old female with a history of hysterectomy for uterine leiomyoma was admitted for lower limb oedema and progressive dyspnea of 5 months' duration. Transthoracic echocardiography and contrast-enhanced computed tomography showed a large mass extending through the inferior vena cava into the right chambers of the heart. As there was a suspicion of an intravenous thrombus, the patient underwent surgical resection. The histopathology of the resected mass led to a diagnosis of Intravascular leiomyomatosis with intracardiac extension.

Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their main responsibility is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. While on the other hand, they must allow polymerase enzymes to access DNA...
