Rectal neuroendocrine tumors are uncommon neoplasms that historically were regarded as having an indolent course. Due to the widespread use of screening colonoscopy neuroendocrine tumors of the rectum are identified with increasing frequency. More recent literature has suggested that rectal neuroendocrine tumors may progress in a more malignant fashion than previously believed. In this case-bas...

Authors analyze the characteristics of the stage pT1 and pT2 colorectal cancer and carry their experience on 68 patients operated. The survival of the colon carcinoma has been of 91% to 2 years and 88% to 5 years, while for the rectum has been of 90% to 2 years and 84% to 5 years. The attitude of the Authors has been to perform radical surgery. Lymph node metastases has been taken like only sur...

Rectovaginal fistula with atresia ani is a congenital condition that affects the anal opening and rectum by the formation of an abnormal connection between the rectum and vagina. This was diagnosed in a domestic short hair kitten. The presenting physical abnormalities included depression, dehydration, partial tail agenesis, anal atresia and a discharge of watery feces from the vaginal opening. ...

Carpeted villous adenomas of rectum may be extensive and not suitable for transanal excision or Endoscopic mucosal resection. We present a case of such lesion extending from anorectal junction to rectosigmoid region. After biopsy and staging, this was managed by a sphincter saving procedure, i.e. a combination of transabdominal total mesorectal excision and transanal intersphincteric dissection...

Cutaneous metastases of rectal adenocarcinoma is a rare phenomenon. We present a 65 year-old man with a painless nodule on the scrotal skin. Excisional biopsy of the nodules revealed a metastasis from rectum adenocarcinoma. Afterwards, the left scrotum was treated with a radiation therapy and the patient also received a salvage chemotherapy. The patient is still alive without any distant metast...

Hand metastases occur infrequently, and metastatic tumors in the soft tissue of the hand caused by rectal cancer are extremely rare. We report a case here. The patient was a 76-year old man. He underwent Miles operation for rectal cancer located in the lower portion of the rectum. Histopathologically, the resected specimen showed well-differentiated adenocarcinoma. Six years postoperatively, a ...

PURPOSE In SBRT for prostate cancer, higher fractional dose to the rectum is a major toxicity concern due to using smaller PTV margin and hypofractionation. We investigate the dosimetric impact on rectum using endorectal balloon (ERB) in prostate SBRT. MATERIALS AND METHODS Twenty prostate cancer patients were included in a retrospective study, ten with ERB and 10 without ERB. Optimized SBRT ...
