[Sentinel lymph node mapping in patients with colorectal cancer].

Unlabelled: The colorectal cancer is the most frequent and clinically significant tumor of the gastrointestinal tract. For more than 100 years, radical lymphadenectomy has been the diagnostic and therapeutic gold standard for the management of metastatic nodal disease. More than 50% of patients are initially present with I and II stage of the disease.

[Pathologic handling and investigation of surgical resected specimen in rectal cancer].

A methodic for pathologic handling and investigation of surgical resection specimen in rectal cancer is presented. It is conformed with recent trends of multidisciplinary approach to rectal cancer. Surgeon is involved in macroscopic investigation of the fresh specimen, whether pathologist is responsible for macroscopic and histological examination of the fixed specimen.

[Rare case of florid vascular proliferation of small intestine complicated with intussusception and bowel obstruction].

Vascular abnormalities of the intestines are unusual. We present a florid benign vascular proliferation of the jejunum in one adult patient, presented with intussusception. In this cases, the proliferation was sufficiently exuberant to raise the possibility of angiosarcoma as a diagnostic consideration.

[The influence of the preoperative radiotherapy upon the pathological characteristic of the rectal cancer].

Unlabelled: The preoperative radiotherapy, leads to the reduction of the tumor, mainly through the destruction of the peripheral, well oxygenized tumor cells. These could change the remoteness of the tumor, from the sphincter and to influence on the type of operation, increasing the share of the conserving surgery. The aim of this study is to determine the frequency of these changes and their influence on the surgical approach.

[Stage migration after biopsy of internal mammary sentinel lymph node in breast cancer patient].

The development of sentinel lymph nodes biopsy rouses a newer interest to internal mammary lymph nodes region. We report a case of internal mammary sentinel lymph nodes biopsy of a woman with breast cancer leaded to stage migration. A 71 years old woman with upper medial quadrant left breast cancer is reported.
