Background: Intraductal papillary neoplasm of the bile duct (IPNB) is a relatively rare bile duct neoplasm in the multistep carcinogenesis pathway towards cholangiocarcinoma. The diagnosis of IPNB is challenging, and its malignant potential means that its prognosis is related to the performance of R0 resection. We experienced a patient with IPNB detected during close examination of colonic dise...

Choriocarcinoma (CC) is a malignant tumor of trophoblastic tissue composed cytotrophoblastic, intermediate and syncytiotrophoblast cells. predominantly has gestational origin. The non-gestational type said to arise from the gonads pluripotent germ It rapidly invasive metastasizes widely, but it good response chemotherapy once identified. Metastatic choriocarcinoma are extremely rare in breast. ...

Pulmonary tumor embolism syndrome is a rare phenomenon that can occur in patients who have an occult neoplasm that metastasizes. We describe a case of an elderly woman with an undiagnosed colon cancer who suffered from respiratory distress and compromised pulmonary blood flow from micrometastasis in the pulmonary arteries.

Certain species of bacteria are known to be associated with colorectal cancer. We report a case of adenocarcinoma of the colon with bacteraemia and liver abscesses due to Streptococcus intermedius. The isolation of this organism should prompt investigation for colorectal neoplasm, which may be present but asymptomatic, without metastases, and therefore at a curative stage.

Primary schwannoma of the large intestine is an extremely rare neoplasm. Here, we report two cases of colonic schwannoma confirmed pathologically after laparoscopic resection. A 52-year-old female and a 59-year-old female were referred by their general practitioners to our coloproctologic clinic for further evaluation and management of colonic submucosal masses. Colonoscopies performed in our i...

Cronkhite-Canada syndrome (CCS) is a rare nonfamilial polyposis syndrome characterized by epithelial disturbances both in the gastrointestinal tract and in the epidermis. The pathologic finding of the polyp is usually a hamartomatous polyp of the juvenile type; however, the possibility of serrated adenoma associated malignant neoplasm was reported in some Japanese cases. Up till now in South Ko...

Here we reported one rare case of colon composited B cell lymphoma associated with adenocarcinoma. The composited B cell lymphoma composed of extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) and large B-cell lymphoma. Additionally, adjacent intestinal mesenteric lymph modes were involved. And interestingly, schistosome infection was also found in lym...

The thyroid gland is a known site for metastatic tumors from various primary sites. Thyroid metastases are not an exceptional finding at autopsy, and they are encountered in 2% to 9% of the patients with malignant neoplasm. The most frequent tumors to metastasize are breast, lung, melanoma, and kidney carcinomas. Despite the fact that it is one of the largest vascular organs in the body, clinic...

A primary clear cell adenocarcinoma of the colon is a rare oncologic entity. The current study presents a case of such a tumor in the transverse colon of a 26-year-old male, and describes the computed tomography features of the neoplasm. The tumor appeared as an extensive extracolic mass, which displaced the loop of the small bowel and pancreas, and invaded the spleen. A laparotomy was performe...
