Colorectal carcinoma (CRC) is a common pathology in the adult population but remains very rare neoplasia childhood with delayed diagnosis and advanced stage grim prognosis that can be fatal, research regarding pediatric adenocarcinoma remain rare. IT represents approximately 1% of neoplasms. It usually associated predisposing genetic factors; this closely linked inheritance familial syndromes. ...

As well known, signet-ring cell carcinoma (SRCC) is a rare histological subtype of colorectal adenocarcinoma, which has been associated with poor prognosis and resistant to non-surgery therapy compared with common adenocarcinoma. In this study, we assessed the effect of preoperative radiotherapy (PRT) for locally advanced rectal SRCC in a large patient group from the Surveillance, Epidemiology,...

Three cases of incidental carcinoid tumors have been identified in the surgical margin of rectal adenocarcinoma resection specimens. In all cases the rectal carcinoids exhibited low-risk features, such as a tumor size <10 mm, no muscularis propria invasion and no lymph node involvement. No further excision was conducted and the three cases were followed up for 38, 26 and 14 months, respectively...

Primary rectal adenocarcinoma metastatic to the breast is an exceedingly rare event. Its management differs from that of primary breast cancer, as illustrated by this case. A 63-year-old woman presented with a breast lump 30 months after abdominoperineal resection for rectal adenocarcinoma, stage T₃N₁M₀ (stage III), followed by standard postoperative radiochemotherapy. The patient underwent a m...

BACKGROUND The most common pattern of recurrence of gastric cancer (GC) is peritoneal dissemination. However, rectal metastasis via hematogenous or lymphatic spread is exceedingly rare. We present a case of a 65-year-old man with an intramucosal GC who developed a rectal recurrence, possibly via a hematogenous route. CASE PRESENTATION A 65-year-old man underwent curative endoscopic submucosal...

This study evaluated the 4-year results of 32 patients with T1N0 low-lying rectal adenocarcinoma treated solely with californium-252 (Cf-252) neutron intracavity brachytherapy (ICBT). Patients were solicited into the study from January 2008 to June 2011. All the patients had refused surgery or surgery was contraindicated. The patients were treated with Cf-252 neutron ICBT using a novel 3.5-cm d...

BACKGROUND The possible involvement of inflammation on colorectal carcinogenesis has potential prognostic, preventive and therapeutic implications. We investigated immunohistochemically whether C-reactive protein is expressed in human primary rectal adenocarcinoma and assessed its relationship with clinicopathological findings. METHODS Ninety-one rectal cancer samples and 22 normal control sa...

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 ...

Small bowel obstruction (SBO) refers to the inability of contents pass through lumen small intestine. This is a common surgical emergency in United States. Although intra-abdominal adhesions are predominant cause, SBO can occur secondarily various etiologies, be it one cause or several. Management secondary and metastasized rectal adenocarcinoma, complicated by pulmonary, hepatic, ureteral dise...

Liver metastases from colorectal carcinoma commonly form nodular lesions in the liver parenchyma. We report a case of liver metastasis from rectal adenocarcinoma that extended predominantly into the bile duct. A 62-year-old Japanese man underwent low anterior resection for rectal adenocarcinoma 9 years ago. Approximately 3 years later, he underwent radiofrequency ablation therapy for a metastat...
