İntroduction:Rhabdomyomas are rare bening tumors arising from striated muscle. They are divided topographically into cardiac and extracardiac. Cardiac rhambdomyomas, the most common type, represent 90% of cardiac tumors of infancy. Fibroma is the scond most common bening cardiac tumor after rhabdomyoma. Extracardiac rhabdomyomas are classified into three subtypes ‘ adult, fetal, and genital type’ based on their clinical and histological features. The head and neck region is the principle site in the extracardiac rhabdomyomas and they are extremely rare tumors. İn the literature, extracardiac rhabdomyomas arising from mediastinum, stomach, esophagus, extremity were rarely reported. There has not been report of rhabdomyoma arising from diaphragma. We present a 2-year-old case with with fetal type of extracardiac rhabdomyoma arising from diaphragma and cardiac fibroma . Case: A boy was admitted to the hospital due to cyanosis during crying .Echocardiographic examination was detected a hypoechogen (24*23*18 mm) mass in the apex of left ventricle. After this, abdominal MR scanning suggested a solid (55*17*28 mm) mass arising from the right diaphragma. Furthermore additional anomalies are cleft lip and palate, hypoplasia of the corpus callosum and macroephaly. The mass in the left ventricle was completely removed by cardiovascular surgeons. Histopathological examination was cardias fibroma. We performed laparoscopic removal for right diaphragmatic mass and diaprgamatic defect repair by laparoscopy. We put a drainage tube in the right hemithorax. The case was discharged in the second postoperative day after the drainage tube was removed. Histopathological examination was intermediate type of rabhdomyoma. Conclusion:Cardiac fibromas and the fetal type of extracardiac rhabdomyomas are bening tumors and seem rarely. Simultaneously the both of fibroma and rabhdomyoma and extracardiac rhabdomyomas arising from the diaphragma has not been reported before. Minimal invasive surgery may be appropriate due to feasibility and shorter time for hospitalization.
