1/226. Calcification in mucinous cholangiocellular carcinoma.Calcification is rarely seen in cholangiocellular carcinoma. We herein report the case of a 53 year-old man with calcification in a cholangiocellular carcinoma. Because imaging studies had revealed coarse calcified foci, hepatolithiasis was suspected pre-operatively. The patient underwent a laparotomy in which intra-operative cholangioscopy revealed no gallstones but did reveal an unsuspected tumor with abundant mucin. A left hepatic lobectomy with resection of the extrahepatic bile duct was performed. The tumor histology was mucinous adenocarcinoma with calcification. In the English language literature, we found 9 cases of cholangiocellular carcinoma with macroscopic calcification. Six of these cases were mucinous adenocarcinomas. Roentgenologic examination revealed coarse calcification in 7 cases and fine calcification in 2 cases. Clinicians should note that cholangiocellular carcinoma, especially the mucinous variant, may be accompanied by coarse calcification.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
2/226. Calcification of presumed ovarian carcinoma brain metastases following radiotherapy.Multiple brain metastases from ovarian carcinoma are rare. CT findings are reported in a case treated with whole brain radiation therapy and chemotherapy. Radiological complete-calcified brain metastases following treatment and long morphological changes occurred. Delayed neurological findings in relation to treatment are considered. Long survival with unmodified calcified lesions may suggest a stabilization of CNS disease.- - - - - - - - - - ranking = 0.5keywords = carcinoma (Clic here for more details about this article) |
3/226. calcium oxalate crystals (Weddellite) within the secretions of ductal carcinoma in situ--a rare phenomenon.A case is described in which calcium oxalate (Weddellite) crystals were identified in an area of ductal carcinoma in situ of the breast. Seventy other cases were examined but no evidence of Weddellite was detected. This is evidently a rare phenomenon in carcinoma in situ.- - - - - - - - - - ranking = 1.4379223347802keywords = ductal carcinoma, carcinoma, ductal (Clic here for more details about this article) |
4/226. Recurrent ductal carcinoma in situ after total mastectomy.A case report is presented of a woman with recurrent DCIS occurring several years following a total mastectomy, the diagnosis of which was aided by a subpectoral saline implant. A discussion of factors associated with recurrence and a review of the literature is provided. A role for selective use of mammography in screening postmastectomy reconstructed breasts in patients at high risk for recurrence is suggested.- - - - - - - - - - ranking = 1.0703378678242keywords = ductal carcinoma, carcinoma, ductal (Clic here for more details about this article) |
5/226. Radial scar with microcalcification mammographic-pathologic correlation: case report.Radial scar, a descriptive term for a pathologic lesion, is composed of central area of fibroelastosis and distorted ducts, and peripheral zone of intraductal hyperplasia. This lesion often presents as a spiculated lesion, sometimes with microcalcifications, on mammography which may mimic malignancy such as tubular carcinoma. We report a case of radial scar with clustered microcalcifications incidentally found in the screened mammogram.- - - - - - - - - - ranking = 0.15150876045575keywords = carcinoma, ductal (Clic here for more details about this article) |
6/226. Ductal adenocarcinoma of the pancreas with intratumoral calcification.We present two cases of ductal adenocarcinoma of the pancreas with intratumoral calcification. The two cases indicate two different etiologies for intratumoral calcification in ductal adenocarcinoma. Thus, the possibility of adenocarcinoma should be considered when a tumor with intratumoral calcification is found, although the incidence of intratumoral calcification in the ductal adenocarcinoma of the pancreas remains rare.- - - - - - - - - - ranking = 0.95452628136726keywords = carcinoma, ductal (Clic here for more details about this article) |
7/226. Renal cell carcinoma with massive osseous metaplasia and bone marrow elements.Focal calcifications are frequently seen in renal masses and may be present in renal cell carcinomas. Metaplastic bone formation, on the other hand, is a rare event. We report a unique case of a large calcified renal cell carcinoma with massive osseous metaplasia and bone marrow elements. The clinical and pathologic differential diagnosis for this tumor is discussed along with a review of the literature on this unusual phenomenon.- - - - - - - - - - ranking = 0.6keywords = carcinoma (Clic here for more details about this article) |
8/226. Supradiaphragmatic manifestations of papillary serous adenocarcinoma of the ovary.AIM: To illustrate unusual patterns of isolated supradiaphragmatic presentation and relapse of papillary serous adenocarcinoma of the ovary. methods: Retrospective study of five women (26-57 years) managed by a specialist gynaecological oncology unit. RESULTS: Three women relapsed in the neck, mediastinal or axillary nodes 3 to 5 years after complete abdomino-pelvic remission. Two women presented with pleural or cervical lymph node metastases respectively 2 and 13 years before the primary pelvic tumour was discovered. Clinical presentations in these five women mimicked metastatic thyroid and breast cancer and mesothelioma. In four of the five woman supradiaphragmatic nodal disease was heavily calcified. CONCLUSION: women with papillary serous ovarian cancer may develop supradiaphragmatic disease without evidence of peritoneal metastasis or primary pelvic tumours. Isolated supradiaphragmatic relapse may occur many years after complete remission of abdomino-pelvic disease. Calcification in supradiaphragmatic lymph nodes should not be assumed to be due to old granulomatous disease as this may be the only clue to relapsing disease. review of prior histology and use of immunohistochemical stains were valuable in diagnosis of these cases.- - - - - - - - - - ranking = 0.5keywords = carcinoma (Clic here for more details about this article) |
9/226. Hepatocellular carcinoma with ring calcification: report of two cases.Two cases of hepatocellular carcinoma (HCC) with ring calcification are reported together with their CT findings. HCC in both cases showed little early enhancement followed by delayed enhancement on dynamic CT. The pathologic specimen in one case showed HCC with fairly abundant fibrosis, and calcification was noted underneath the thick fibrous capsule, which might explain the enhancement pattern on CT.- - - - - - - - - - ranking = 0.5keywords = carcinoma (Clic here for more details about this article) |
10/226. Ruptured retroperitoneal mucinous cystadenocarcinoma with synchronous gastric carcinoma and a long postoperative survival: case report.We describe an 86-year-old woman with a long survival following surgey for a massive retroperitoneal mucinous cystadenocarcinoma and a synchronous gastric carcinoma. Computed tomography showed a huge tumor with septation and calcification. Upper gastrointestinal radiography showed the additional gastric lesion. At operation, the 23 x 20 x 12-cm retroperitoneal tumor had ruptured. Tumor resection and distal gastrectomy including regional lymph nodes were performed. Mucinous peritoneal implants were removed as completely as possible. Histologically, the mucinous tumor showed limited invasion, whereas the poorly differentiated gastric adenocarcinoma showed no serosal invasion. Among 18 retroperitoneal mucinous cystadenocarcinomas reported in the English literature since 1965, only ours was associated with gastric carcinoma. Despite peritoneal implants, our patient has survived for 6 years without clinical recurrence. As at other sites, retroperitoneal mucinous cystadenocarcinoma often grows slowly. Total removal, even after peritoneal dissemination, can result in long survival.- - - - - - - - - - ranking = 1.4keywords = carcinoma (Clic here for more details about this article) |
