Basaloid squamous cell carcinoma occurs in various organs including the upper respiratory tract, the base of the tongue, pharynx, larynx, breast, uterine cervix and anus. It is a rare tumor, but it must be distinguished from other malignancies because of its aggressive clinical behavior. Many cases present in the advanced stage at the time of diagnosis. We present here a case of esophageal basaloid squamous cancer that was diagnosed in 75-year-old male patient who had dysphagia and throat pain, and this was accompanied by squamous cell cancer of the tongue base, as was determined by laryngoscopic and esophagogastroscopic examination.

The presence of severe pulmonary arterial hypertension (PAH) in patients with atrial septal defect (ASD) is still thought to preclude shunt closure, although there are several reports of good clinical outcomes after vasodilator therapy. We report the case of a young woman with ASD and severe PAH who was able to successfully undergo percutaneous shunt closure following 1 year use of the oral endothelin receptor antagonist, bosentan.

Lymphangioma usually occurs in children and usually involves neck and axillary region. Renal or perirenal cystic lymphangioma, hepatic lymphangiomatosis and splenic lymphangiomatosis are very rare disorders. Perirenal cystic lymphangioma combined with multiple hepatic cysts or multiple splenic cysts suspected to be lymphangiomatosis has not been reported in adults in this country until now. The patient was a 43-year-old woman who had been diagnosed with multiple splenic cysts about ten years ago. She presented with a perirenal cystic lesion discovered incidentally and we detected small multiple hepatic cysts additionally with abdominal CT. We removed perirenal cyst surgically and a perirenal lymphangioma was confirmed.

BACKGROUND: A Stellate ganglion block (SGB) is a sympathetic nerve block method which has been used most frequently in pain clinics due to its wide range of indications. However, SGB leads to regional sympathetic denervation of the heart and to changes in the hemodynamics. The aim of this study was to compare hemodynamic effects as well as echocardiographic changes after a left SGB (LSGB). METHODS: Fourteen healthy male volunteers were studied. The LSGB was performed with 1% mepicacaine 6 ml. Arterial blood pressure, electrocardiographic and echocardiographic variables were measured before the LSGB, 15 and 30 minutes after the LSGB. RESULTS: Arterial blood pressure, ejection fraction and transmitral inflow velocity variables showed no significant changes compared to pre-LSGB values. P-P interval increased significantly 15 minutes after the LSGB, and the Q-T interval increased significantly 30 minutes after the LSGB. The diastolic pulmonary venous flow velocity decreased significantly 15 minutes after the LSGB. CONCLUSIONS: These results showed that a LSGB decreased the heart rate without detrimental changes of left ventricular relaxation in healthy male volunteers.
