1/252. Embolic vascular seeding of endometrial adenocarcinoma, a complication of hysteroscopic endometrial biopsy.OBJECTIVE: A case of embolic vascular seeding of endometrial adenocarcinoma following hysteroscopy is reported. methods: This phenomenon was recognized in the uterus specimen from a hysterectomy performed 1 week after hysteroscopic endometrial biopsy. Tissue processing artifact was excluded. RESULTS: Since the patient was otherwise low risk, treatment was limited to hysterectomy. The patient was not given adjuvant therapy. Two years later she remains alive and well with no evidence of disease. The surgical, morphologic, and clinical features of this case are presented and illustrated. CONCLUSION: Previous reports of peritoneal tumor seeding associated with hysteroscopy are reviewed. Tumor embolization during hysteroscopic endometrial biopsy was not followed by tumor recurrence in this case.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
2/252. Organ-preserving surgery of renal cell carcinoma: report of four cases.Authors removed the renal tumour of four patients by means of resection in an organ-preserving manner. Of the four patients, one had bilateral carcinoma. The right-sided carcinoma of this patient was removed by resection while the other kidney was removed radically, by transabdominal approach. In three of the four cases which were in the process of stages T1 and N0M0, organ-preserving surgery was performed in the presence of intact opposite kidneys. Authors point out the fact that the resection method might be indicated even in the case of early (T1) stage tumours with intact opposite side kidneys. Furthermore, they do not recommend the enucleation of renal carcinomas for the surgical treatment of kidney tumours, since experimental studies have proved that these tumours can be transferred into the parenchyma of the kidney through the pseudocapsule of the tumour.- - - - - - - - - - ranking = 1.4keywords = carcinoma (Clic here for more details about this article) |
3/252. Peritoneal mucinous carcinomatosis after laparoscopic-assisted anterior resection for early rectal cancer: report of a case.Minimally invasive colon surgery has been shown to be both technically feasible and a safe alternative to laparotomy. Its efficacy for the curative resection of colorectal cancer, however, remains controversial. Of major concern are the increasing reports of port-site recurrence after use of laparoscopic techniques in malignant disease. In this article a heretofore unreported complication of peritoneal mucinous carcinomatosis after laparoscopic-assisted anterior resection for early stage rectal cancer is presented. Isolated peritoneal recurrence is rare after curative resection of Stage I rectal cancer. The effect of pneumoperitoneum on tumor dissemination is discussed.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
4/252. Extraosseous metastases of hepatocellular carcinoma detection and therapeutic assessment with Tc-99m PMT SPECT.Owing to recent advances in imaging technology and radiologic intervention, survival rates in patients with hepatocellular carcinoma have improved markedly. However, such prolonged survival has resulted in an increase in extrahepatic metastases. Tc-99m (Sn)-N-pyridoxyl-5-methyltryptophan (Tc-99m PMT), developed for hepatobiliary scintigraphy, has been used to visualize extrahepatic metastases, with most related reports limited to osseous metastases. The authors report two cases of hepatocellular cancer presenting as a hypopharyngeal metastasis and intraperitoneal dissemination along the tract of a fine-needle biopsy. Lesions undetectable on planar imaging could be visualized by Tc-99m PMT SPECT.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
5/252. Port-site metastasis following laparoscopic lymphadenectomy for adenosquamous carcinoma of the cervix.Although incisional metastases following surgery for cervical cancer are extremely rare, port-site disease following minimal-access surgery is becoming increasingly reported. We report a case of a metastasis which occurred at a port site following laparoscopic removal of lymph nodes affected by cervical adenosquamous carcinoma. This report adds to the literature suggesting that cutaneous tumor deposition may be enhanced by this method of surgery.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
6/252. Intraperitoneal seeding of ruptured hepatocellular carcinoma: case report.We report a solitary intraperitoneal recurrence in a long-term survivor after rupture of hepatocellular carcinoma. ultrasonography demonstrated the finding of a lobulated mass with a "mosaic" appearance. The patient underwent resection of this implant and is currently disease free. We emphasize the importance of periodic surveillance of disseminated metastases of this condition.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
7/252. Port site metastases after laparoscopic cholecystectomy for an unexpected gallbladder carcinoma.Laparoscopic cholecystectomy is a proven, well-accepted surgical technique for removing the diseased gallbladder and has rapidly become the surgical procedure of choice over conventional open cholecystectomy. Radiologists must be aware of the possibility of inadvertent dissemination of incidental gallbladder cancer during laparoscopic cholecystectomy. We report a case of this unusual complication: a patient with port site metastases after laparoscopic cholecystectomy for an unexpected gallbladder carcinoma at an early stage.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
8/252. Tumor seeding of the jejunostomy site after transhiatal esophagectomy for esophageal carcinoma.A 65-year-old male patient with squamous cell carcinoma of the esophagus had a transhiatal esophagectomy after a prophylactic tube jejunostomy. The tube was removed 3 weeks after surgery. Ten months later, a painless 2-cm abdominal mass was noted at the previous jejunostomy site. Subsequent segmental resection of the jejunum disclosed metastatic squamous cell carcinoma of the esophagus. It is possible that tumor seeding may develop at the jejunostomy site after transhiatal esophagectomy for esophageal carcinoma.- - - - - - - - - - ranking = 1.4keywords = carcinoma (Clic here for more details about this article) |
9/252. Cytogenetic monoclonality in multifocal uroepithelial carcinomas: evidence of intraluminal tumour seeding.Twenty-one multifocal urinary tract transitional cell carcinomas, mostly bladder tumours, from a total of six patients were processed for cytogenetic analysis after short-term culturing of the tumour cells. Karyotypically related, often identical, cytogenetically complex clones were found in all informative tumours from each case, including the recurrent tumours. Rearrangement of chromosome 9, leading to loss of material from the short and/or the long arm, was seen in all cases, indicating that this is an early, pathogenetically important event in transitional cell carcinogenesis. The presence of related clones with great karyotypic similarity in anatomically distinct tumours from the same bladder indicates that multifocal uroepithelial tumours have a monoclonal origin and arise via intraluminal seeding of viable cancer cells shed from the original tumour. Later lesions may develop also from cells shed from the so called second primary tumours. The relatively complex karyotypes seen in all lesions from most cases argue that the seeding of tumour cells is a late event that succeeds the acquisition by them of multiple secondary genetic abnormalities.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
10/252. Laparoscopic port-site metastasis of an early stage adenocarcinoma of the cervix with negative lymph nodes.BACKGROUND: Port-site metastasis (PSM) following laparoscopic surgery for cancer is being increasingly recognized as a potential problem; the majority of cases appear following laparoscopy for a pelvic mass that subsequently proved to be malignant or in the case of a disseminated intraperitoneal disease. The rare cases of PSM following laparoscopy for endometrial and cervical cancer have all been associated with the presence of regional lymph node metastasis or disseminated disease in the peritoneal cavity. We present here a case report of PSM in the absence of spread beyond the primary tumor. CASE: A 48-year-old woman with stage IA1 adenocarcinoma of the cervix was treated with laparoscopically assisted vaginal hysterectomy, bilateral salpingo-oophorectomy, and bilateral pelvic node dissection. The pathologic study revealed an endocervical adenocarcinoma confined to the cervix with negative lymph nodes. Nine months postoperatively, a cutaneous metastasis at the port-site was diagnosed. This was treated with wide local excision of the recurrence and the port-site track. Explorative laparotomy and para-aortic node sampling showed no evidence of recurrence elsewhere. CONCLUSION: This case emphasizes the risk for PSM in laparoscopic surgery performed for early stage disease.- - - - - - - - - - ranking = 1.2keywords = carcinoma (Clic here for more details about this article) |
