[Retroperitoneal tumors: personal experience]. / I tumori retroperitoneali: esperienza personale.

The Authors experience in five retroperitoneal tumors with symptoms and histopathological characteristics not different from those described in the Literature, is here reported. Topographic findings, classification, and incidence of retroperitoneal tumors as referred by various Authors are discussed. Two aspects are particularly pointed out: the histological type and the surgical strategy for their removal. Concerning the first aspect, the Authors underline that benign lesion may have an optimal outcome and a long survival, unlike the malignant ones, which have always unfavourable prognosis, despite adjuvant and complementary therapy (radiotherapy, chemotherapy). As for the second aspect, surgery is the treatment of choice even when other organs different from those exclusively retroperitoneal, may be involved in the demolition.

[Iatrogenic lesion of the thoracic duct in the neck. Presentation of a case]. / Lesione jatrogena del dotto toracico al collo. Presentazione di un caso.

Authors report a case of iatrogenic lesion of thoracic duct of the neck occurred during clearing the left latero-cervical zone for thyroid cancer. After reporting the relative unusuality of this complication, authors underline that in the literature there are always more frequent reports about lymphatic lesions in every district of the body due to more aggressive treatments. Although this case has been treated with a relatively simple operation (finding and binding the duct), treatment of these lesions is not always so simple and therefore knowledge of metabolic problems of these disorders, as well as the selection of the surgical strategy, should be always carefully evaluated for recovery of this disease.
