Seventeen cases of @entity1358 have been reported in the literature. Approximately half of the reported cases show combined features of @entity1606 . Presented herein is a case of @entity1358 in a 37-year-old Japanese male who had been treated for 10 years with @entity6359 for duodenal @entity1066 . He suffered from @entity2459 @entity662 at presentation and @entity3291 was suspected. He was treated by atriotomy and a @entity5 was removed from the right atrium and pulmonary artery. Histological examination, however, revealed it to be @entity4153 . Accordingly, a radical operation was performed for the removal of a @entity5 found in the right kidney. Histological examination of the @entity5 confirmed the presence of @entity1358 without any features of @entity1606 . It is reported that long-term administration of an @entity112 2 (H2) receptor antagonist may produce @entity5 in rodents and enterochromaffin-like cell hyperplasia in @entity1 . The possible relationship between @entity3270 and H2 receptor antagonist therapy is discussed.

@entity1358 ( @entity3270 ) without features of XXXX .
