“…Our observation differs from reported cases of ectopic liver tissues in human lungs ( Hudson and Brown, 1962 ; Lasser and Wilson, 1975 ; Mendoza et al, 1986 ; Iber and Rintala, 1999 ; Chalak and Parham, 2007 ; Choi et al, 2008 ; Tancredi et al, 2010 ; Bannon et al, 2013 ). In Mgp − / − mouse, the lungs still develop and function, although the alveolar structures and pulmonary vasculature are abnormal.…”

“…Heterotopic liver is a rare entity, defined as macroscopic or microscopic foci of liver tissue present outside of the native liver, and is more frequently in the abdominal cavity attached to various organs, like the spleen, gallbladder, pancreas, umbilical fossa, adrenals, omentum and retroperitoneum [1,2]. Around 100 cases of ectopic liver have been reported [3], and approximately twenty cases of supradiaphragmatic ectopic liver have been presented to date, usually located in the intrathoracic cavity and pericardium, and most of them connected to the main liver by a small pedicle that passes through the diaphragm [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. To our knowledge, there are only two reported cases of ectopic liver tissue identified inside the cardiac chambers in living subjects, one being an adult case, and the other one a pediatric case [4,5].…”

Heterotopic Hepatic Polyp Identified in the Right Atrium

Heterotopic liver tissue has been described in the literature, more commonly observed in the abdominal cavity than in the thoracic cavity. In most reported supradiaphragmatic ectopic liver cases, there was a pedicle passing through the diaphragm and connecting the liver with the ectopic tissue. We report a case of heterotopic liver tissue misdiagnosed preoperatively as atrial myxoma. A 40 yearold woman presented to the Emergency Department with recurrent acute nocturnal respiratory distress. Transthoracic echocardiogram revealed a 2 x 2.5 cm floating mass in right atrium at the junction of inferior vena cava. The patient underwent sternotomy for resection of the atrial mass based on presumed diagnosis of cardiac myxoma. Pathologic examination demonstrated polypoid encapsulated benign hepatic tissue. We presented this case because it is an extremely rare condition that is commonly misdiagnosed, and is the second case to date, to the best of our knowledge, of supradiaphragmatic heterotopic liver polyp identified inside the cardiac chambers in a living adult person.

“…Ultrasonography is often negative, as in our case, while chest X-ray may show the presence of a radio-opaque mass, better evident in the lateral projection. A differential diagnosis should then be made with posterior pleural, pulmonary and mediastinal masses such as lymphomas, neurogenic tumors, benign fibrous tumors, pericardial, or esophageal neoplasms [ 15 , 16 ].…”
