[Mucha-Habermann disease and orthotopic heart transplant. Case report].

Background: Mucha-Habermann disease is a cutaneous clinical manifestation of unknown etiology that frequently appears in young patients. The aim was to present Mucha-Habermann disease that occurred in an old man who had a heart transplant.

Clinical Case: a 62 year-old male, heart transplant recipient, who four years after that transplantation procedure presented with papular lesions in neck, thoracic members of which extended to all body surfaces and that evolved vesicles and pustular lesions.

Pleomorphic malignant histiocytoma of pulmonary arteries presenting as pulmonary aneurysms.

Pulmonary aneurysms and primary neoplasms of the great vessels are very rare entities; pulmonary aneurysms are commonly associated with congenital heart diseases, and less frequently in atherosclerosis, medial cystic necrosis, trauma, infection, and inflammatory processes. Many patients have pulmonary hypertension, most frequently resulting from pulmonary artery sarcomas mimicking pulmonary thromboembolism. Symptoms are vague.

[Distant heart procurement for transplantation].

Background: The low availability of organ donors is a serious hindrance to heart transplantation. Long-distance organ procurement has been accepted as an option despite longer ischemic time for the heart.

Methods: Long-distance procurement from outside Mexico City in adult patients with terminal heart failure submitted to orthotopic heart transplantation between February 1st 2011, and January 31st 2012, was assessed.
