Catecholamine-secreting paraganglioma. The problem of classification.

Sudden catecholamine release, associated congestive heart failure, acute injury changes on ECG, and elevation of cardiac enzyme levels were observed after biopsy of a mediastinal mass. Five months later, a normal ECG and coronary arteriogram were recorded. Initial severe avoid unexpected catecholamine release, we recommend that all paragangliomas be evaluated for catecholaime production.

[Ultrasound in trauma (FAST)].

During last 20 years ultrasonography has been widely used in Europe to investigate abdominal trauma. In United States it has not been considered a reliable test especially because of its lack of sensitivity in diagnosing parenchymal injuries. Recently American surgeons reconsidered ultrasonography in trauma and codified its use into FAST (Focused Assessment for the Sonographic examination of the Trauma patients). The goal is to detect hemoperitoneum and pericardial effusion. Advantages are remarkable: ultrasound is cost-effective, fast, non-invasive, can be performed by surgeons even on unstable patients. FAST is now included in ATLS framework for examination of thoraco-abdominal trauma.

[A rare case of Merkel's tumor with intestinal metastases].

A rare case of intestinal metastasis of a neuroendocrine carcinoma of the skin (Merkel Cell Tumor) is reported. The primary tumor was excised from the left arm two years earlier and followed an aggressive course with lymph-nodes, tonsillar and intestinal spread. Histologically, the intestinal lesion was similar to the primary tumor with small, undifferentiated cells. Undifferentiated small cell carcinoma and lymphomas of the gastrointestinal tract are to be considered in the differential diagnosis. Merkel Cells Tumor usually affects head and neck (44%) and extremities (48%), and is a highly malignant neoplasia, with early recurrence and distant metastases. Wide surgical excision of the primary lesion is the treatment of choice, while controversial is the role of prophylactic regional lymphadenectomy. Adjuvant radio- and chemo-therapy is frequently associated.
