tumoral infiltration of the mesorectum
25 March 2017tumor spread in the mesorectum
The 1-cm distal margin recommended in patients with low rectal carcinoma could be reduced with insurance to obtain a negative distal margin.
The knowledge of preferential localization of mesorectal metastatic lymph nodes (MLNs) and mesorectal extranodal cancer tissue (EX) would help the pathologist to improve patient’s lymph node staging.

19 September 2016Sexually transmitted proctitis
Sexually transmitted infections such as chlamydia, gonorrhoea, herpes simplex virus and syphilis commonly present with rectal symptoms.

rectal neuroendocrine tumor
27 March 2015According to the 2010 World Health Organization classification, all gastrointestinal neuroendocrine tumors (NETs) are classified as malignant except for L-cell-type (glucagon-like peptide [GLP] and peptide YY [PYY]-producing) NETs.
Non-L-cell immunophenotype and large tumor size are associated with increased tumor grading and staging, concurrently indicating that they are independently poor prognostic indicators in rectal NET patients. Therefore, combining L-cell phenotype and tumor size (...)
