Intestinal manifestation of Buerger's disease in a middle-age female with subsequent transverse colon perforation: A case report and review of literature.

Thromboangiitis obliterans, or Buerger's disease, is a relatively rare nonatherosclerotic, segmental inflammatory and obliterative vascular disease that affects the small- and medium-sized arteries, veins, and nerves. In the acute phase, the lesion presents as an inflammatory, nonsuppurative panarteritis or panphlebitis with vascular thrombosis without necrosis. In the late stage of the disease, the thrombus becomes organized leading to varying degrees of recanalization and subsequent gangrene and amputation.

An unusual case of chronic lymphocytic leukemia with trisomy 12 presenting with prolymphocytic transformation and t(8;21)(q22;q22).

First report of t(8;21)(q22;q22) in a patient with CLL. RUNX1-RUNX1T1 fusion gene resulting from the translocation may have played a role in the prolymphocytic transformation.

The conundrum of ventricular arrhythmia and cardiomyopathy: which abnormality came first?

Ventricular arrhythmia and cardiomyopathy often coexist. Many patients with abnormal ventricular function have either documented premature ventricular contractions (PVCs) or nonsustained ventricular tachycardia and have an increased risk of sudden death from ventricular fibrillation. Tachycardia is a treatable cause of cardiomyopathy.
