1/248. Spontaneous remission of solitary bony metastasis after removal of the primary kidney adenocarcinoma.The second case of spontaneous remission of a biopsy-proved osseous metastasis from a renal carcinoma is reported. The unusual feature of the patient presenting with a right varicocele and no hematuria is extremely rare.- - - - - - - - - - ranking = 1keywords = adenocarcinoma (Clic here for more details about this article) |
2/248. Familial ovarian carcinoma.Familial aggregation of patients with ovarian carcinoma is unusual. A family with four affected members in three consecutive generations is described. The tumors were all of the serous papillary adenocarcinoma type. The pattern of appearance of the malignant disorder in the present family may be explained as the result of transmission of a dominant mutant autosomal gene. The future long term management of such a family might include prophylactic oophorectomy in certain family members, and possibly selective terminations of pregnancies with female fetuses in high-risk women.- - - - - - - - - - ranking = 0.25keywords = adenocarcinoma (Clic here for more details about this article) |
3/248. acanthosis nigricans and wart-like lesions associated with metastatic carcinoma of the stomach.A 63-year-old white man developed malignant acanthosis nigricans one year after a hemigastrectomy for adenocarcinoma of the stomach. Multiple "wart-like" lesions involving the dorsa of the hands, arms and trunk were also present. The malignant acanthosis nigricans in the patient appears to have paralledled the course of the metastatic gastric adenocarcinoma. Discrete verrucous lesions can occur in malignant acanthosis nigricans which histopathologically may show either squamous or basal cell hyperplasia.- - - - - - - - - - ranking = 0.5keywords = adenocarcinoma (Clic here for more details about this article) |
4/248. Well-differentiated adenocarcinoma, gastric foveolar type, of the extrahepatic bile ducts: A previously unrecognized and distinctive morphologic variant of bile duct carcinoma.Two examples of a rare but distinctive morphologic variant of extremely well-differentiated adenocarcinoma of the extrahepatic bile ducts are reported. One tumor arose in the common bile duct of a 51-year-old man; the other arose in the common hepatic duct of a 27-year-old man. Both tumors were composed predominantly (>95%) of gastric foveolar-type epithelium. Because of their bland nuclear features, low mitotic index, and focal polypoid and lobular architecture, they were initially confused with adenomas. Foci of less-differentiated adenocarcinoma and perineural invasion present in the deep portions of the tumors facilitated recognition. The neoplastic cells and extracellular mucin were periodic acid-Schiff- and alcian blue-positive. By immunohistochemistry, the tumor cells expressed cytokeratins 8 and 20 as well as cathepsin d, as reported in normal foveolar cells. Likewise, p53 overexpression was documented immunohistochemically in both adenocarcinomas, which also stained with the Ki-67 antibody. Despite the well-differentiated nature of the neoplasms and their deceptively benign microscopic appearance, one patient developed recurrence and liver metastasis 5 years after surgery. The other patient is disease-free 2 years following a segmental resection of the common hepatic duct, cystic duct, and gallbladder. The cell phenotype of these tumors can be explained by the ability of the bile duct epithelium to differentiate along gastric cell lines.- - - - - - - - - - ranking = 1.75keywords = adenocarcinoma (Clic here for more details about this article) |
5/248. methotrexate pneumonitis induced by intrathecal methotrexate therapy: a case report with pharmacokinetic data.A patient with adenocarcinoma of the breast metastatic to the leptomeninges was treated with 10 doses of intrathecal methotrexate (MTX) administered at intervals of 2 days. Following these treatments she developed fever, hypoxemia, and bilateral pulmonary infiltrates without documented pulmonary infection. autopsy findings were consistent with the pneumonitis that has been associated with intermittent oral, intramuscular, and intravenous MTX therapy. It is suggested that this patient's pulmonary process represented MTX pneumonitis following intrathecal MTX. cerebrospinal fluid and serum MTX concentrations determined retrospectively on frozen samples reflect an atypically rapid transport of MTX from this patient's cerebrospinal fluid to a slowly decaying systemic pool. Because of this, serum MTX levels probably exceeded 10-8M during the entire 20-day course of therapy, thus exposing the pulmonary parenchyma to significant drug concentrations for a prolonged interval. It is suggested that these unfavorable pharmacokinetics may have contributed to this patient's susceptibility to MTX pneumonitis.- - - - - - - - - - ranking = 0.25keywords = adenocarcinoma (Clic here for more details about this article) |
6/248. Adoptive therapy of canine metastatic mammary carcinoma with the human MHC non-restricted cytotoxic T-cell line TALL-104.adoptive transfer of human TALL-104 killer cells into a dog with metastatic mammary adenocarcinoma resulted in 50% reduction of the largest lung metastasis and stabilization of the other lesions for 10 weeks, accompanied by the development of tumor-specific immune responses. Upon halting cell therapy, the dog developed new lung lesions within 10 weeks and died of slowly progressive disease. TALL-104 cell therapy of mice bearing the dog's tumor xenograft induced 65% reduction of local tumor growth and regression of lung metastases in 100% of the animals. The overall findings indicate the therapeutic potential of TALL-104 cells for canine mammary tumors.- - - - - - - - - - ranking = 0.25keywords = adenocarcinoma (Clic here for more details about this article) |
7/248. A case of adenocarcinoma with clear cell carcinoma of the bladder.A case of adenocarcinoma with clear cell carcinoma of the bladder in a 65-year-old male is reported. Our patient had a walnut-sized nodular tumor located on the anterior wall of the bladder. The patient underwent radical cystoprostatectomy with urethral hemi-Koch pouch. Histopathological examination revealed a lesion composed of poorly-differentiated adenocarcinoma and clear cell carcinoma with diffuse sheet patterns of cells with abundant, clear cytoplasm. The patient died of general metastasis 18 months after operation. To our knowledge this is the first case of adenocarcinoma with clear cell carcinoma arising from the anterior wall of the bladder in a male.- - - - - - - - - - ranking = 1.75keywords = adenocarcinoma (Clic here for more details about this article) |
8/248. Adenosquamous carcinoma of the pancreas.BACKGROUND: Adenosquamous carcinoma of the pancreas most probably represents squamous metaplasia of an adenocarcinoma. Metastases are typically an admixture of both elements, but more frequently, adenocarcinoma. methods: A review of 102 pancreaticoduodenectomies for masses of the head of the pancreas done between 1994 and 1998 revealed two patients with adenosquamous carcinoma of the pancreas. RESULTS: Both patients underwent successful pancreaticoduodenctomy, but were found to have nodal metastasis. One patient lived 13 mo and the other lived 14 mo with both dying from metastatic disease. CONCLUSION: Adenosquamous carcinoma of the pancreas is a rare tumor, and because its presentation, clinical features, and course are identical to adenocarcinoma of the pancreas, it should be considered in the differential diagnosis for any mass of the head of the pancreas. survival is poor for these patients. In this series, it was 13 and 14 mo, respectively.- - - - - - - - - - ranking = 0.75keywords = adenocarcinoma (Clic here for more details about this article) |
9/248. Deletion (1)(q12) and double minutes in a metastatic adenocarcinoma of the prostate.cytogenetic analysis after short-term cultures were performed on an invasive and moderately-differentiated prostatic adenocarcinoma. The results showed a normal male chromosomal complement in most metaphases examined. Furthermore, several abnormalities were found, including del(1)(q12), double minute and ring chromosomes, acentric fragments, triradial figures, and near-tetraploid cells.- - - - - - - - - - ranking = 1.25keywords = adenocarcinoma (Clic here for more details about this article) |
10/248. Metastatic adenocarcinoma of gingiva. Report of a case.A case of metastatic neoplasm developing in the gingiva from a primary lesion, probably sited in the gastric mucosa, has been reported. In this case, the first demonstrable metastatic lesion was located in the gingiva. The dentist has a great responsibility in detecting malignancy in the oral cavity because of his opportunities during routine examinations.- - - - - - - - - - ranking = 1keywords = adenocarcinoma (Clic here for more details about this article) |
