Summary:A 57-year-old woman with syncope was admitted. She had a family history of sudden death: two brothers had died suddenly at the age of 47. Transesophageal echocardiography showed numerous prominent trabeculations and deep intertrabecular recesses in the anterior and lateroapical zones. Isotopic left ventricular ejection fraction was 46%. Cardiac catheterization showed coronary arteries with no angiographic lesions. A prominent trabecular zone and deep intertrabecular recesses were seen in the anterior wall on left ventriculography. Right ventriculography was normal. The diagnosis of isolated noncompaction left ventricular myocardium was established. Continuous 24-h electrocardiographic registry showed episodes of polymorphic ventricular tachycardia. Programmed ventricular stimulation performed at the right ventricular apex with up to three extrastimuli failed to induce ventricular arrhythmias. Treatment with beta blockers was initiated, but short runs of polymorphic ventricular tachycardia persisted. A dual-chamber automatic implantable defibrillator was implanted. We discuss the physiopathology of the arrhythmia. It appears that several factors could be responsible for the malignant arrhythmias in this entity.

Digital papillary adenocarcinoma (DPA) is a rare malignant tumor of the sweat glands that often presents as a solitary painless mass on the digits of the hands or feet. We present a rare case of DPA on the ankle in a 54 year-old African American man. Although the most common location for digital papillary adenocarcinoma is on the hands and feet, it can present in other locations. Treatment modalities and concerns such as the level of margin resection, degree of negative margins, and the need for a sentinel lymph node biopsy might be different if the tumor is encountered in locations other than the digits. In the following manuscript, we discuss the natural history of this rare tumor including a review of the current literature with emphasis on documented treatment strategies as well as the approach in treating patients with a unique presentation.

Diffuse alveolar hemorrhage (DAH) is a serious pulmonary complication in patients with autoimmune diseases who are undergoing chemotherapy or have had hematopoietic stem cell transplantation. The use of recombinant factor VIIa (rFVIIa) to treat the acute phase of DAH by endobronchial bronchoscopy has been shown to have a significant clinical impact on the survival and evolution of these patients. We report a clinical case of a patient with DAH secondary to systemic lupus erythematosus (SLE) who was treated with rFVIIa administered using a jet nebulizer, obtaining an adequate hemostatic effect with immediate control of DAH and a significant improvement in gas exchange.
