Metastatic adenocarcinoma presenting as microangiopathic hemolytic anemia (MAHA) and leukoerythroblastic blood picture is rare. We report three patients who presented with MAHA as the initial symptom of metastatic signet ring cell gastric adenocarcinoma. One patient had past history of gastric ulcer. In all these patients the initial diagnosis was based on peripheral blood smear followed by bone marrow biopsy; upper GI endoscopy showed presence of gastric ulcers with focally scattered neo-plastic signet ring cells on histopathology. All patients died within a week of diagnosis. 相似文献

Multiorganic dissemination of a colorectal signet ring cell carcinoma with fulminant clinical course
Longo R Morabito A Carillio G Lanzi G Castellana MA Amici S Fanelli M Gattuso D Gasparini G 《Journal of gastrointestinal cancer》2006,37(1):49-54
Mucinous colorectal cancer with signet ring cell aspects is a rare form of adenocarcinoma representing about 2–5% of large
bowel neoplasms. The tumor frequently presents with late-stage or peritoneal spreading. It can often affect young patients
and diffusely infiltrate through all layers of the intestinal wall. Local recurrence and distant metastases are common in
spite of surgical operation and adjuvant treatment, conditioning a poor prognosis. At the present, early diagnosis and complete
resection are the most important approaches to improve the outcome. In our report we describe a case of a 41-yr-old patient
with very aggressive untreated metastatic colorectal signet ring cell carcinoma. The fulminant tumor progression was really
unexpected and misled every possible medical interpretation, leading to rapid worsening of the patient's clinical conditions
and no chance for chemotherapy treatment. The tumor mimicked the picture observed in the acute leukemia, developing diffuse
infiltration in all serosal membranes, liver, lung, kidneys, multiple lymph nodes, and meninges, as revealed by the post-mortem
medical report. 相似文献

Gastric cancer with metastasis to the gingiva 总被引:3,自引:0,他引:3

The present case report describes a gastric cancer which showed unusual metastasis in the oral region. A 56-year-old male patient underwent total gastrectomy and splenectomy due to advanced gastric cancer in the upper third of the stomach. Fifteen months later, he presented with anorexia and gingival swelling of durations of approximately 3 and 1 month, respectively. The gastric tumor was histologically a signet ring cell and a poorly differentiated cancer with a moderate degree of vascular invasion. Biopsy specimens from the gingival tumor revealed a signet ring cell cancer. Other metastatic sites were the brain, limb bones and abdominal lymph nodes. A bone scintigram revealed an abnormal uptake in the limb bones, while it did not exhibit any abnormality in the oral region. Correlation between the histology of the gingival tumor with that of the gastric cancer, as well as the absence of a gingival tumor at the time of prior gastrectomy, led to a diagnosis that the gingival tumor was a metastasis from gastric cancer. Gastric cancer metastasizing to the oral region, either the osseus or the oral soft tissue, is very rare. Although it cannot be proved without an autopsy, negative findings in the mandible by bone scanning in the present case suggest that direct gingival metastasis can be considered, rather than mandibular metastasis involving the gingiva. Hematogenous spread could be a mechanism of metastasis for this unusual tumor. 相似文献

We encountered a 45-year-old woman with chronic eosinophilic pneumonia associated with rheumatoid arthritis. In May 1997, she was given a diagnosis of rheumatoid arthritis and prescribed non-steroidal anti-inflammatory drugs. After a month, she visited our hospital because of fever and cough. A chest roentgenogram and computed tomographic scan on first admission revealed peripheral infiltrative shadows in the upper fields of both lungs. Approximately 30% of peripheral blood cells were eosinophils. Furthermore eosinophils were elevated in bronchoalveolar lavage fluid and transbronchial lung biopsy specimens. A conclusive diagnosis of chronic eosinophilic pneumonia was made on these grounds. The patient responded well to steroid treatment, but was readmitted a week later because of worsening joint pain and skin eruptions in the lower extremities of both legs. A skin biopsy showed perivascular and interstitial eosinophil infiltration. The combination of steroids, a disease modifying anti-rheumatic drug, and a non-steroidal anti-inflammatory drug proved to be effective. 相似文献

Primary hepatic signet ring cell neuroendocrine tumor is extremely rare and is characterized by distinct intracytoplasmic hyaline vacuoles that are mucin negative and cytokeratin positive. The unique histological features may cause difficulty in diagnosis and delay patient care. Here the authors report a 49-year-old man with an incidental finding of a 2.7 cm liver mass in the absence of chronic liver disease. The resected tumor was grossly unencapsulated but well demarcated with friable tissue texture. Microscopically, the entire tumor consisted of sheets of monotonous cells separated by delicate microvasculature. The tumor cells had granular chromatin, inconspicuous nucleoli, and eosinophilic cytoplasm. Many of the tumor cells had eccentric, pale intracytoplasmic vacuoles resembling signet ring cells in adenocarcinoma. Immunohistochemical studies showed that the tumor cells were positive for neuroendocrine markers and that the intracytoplasmic vacuoles were negative for mucin but strongly positive for cytokeratins. Careful systemic search including OctreoScan scintigraphy (Mallinckrodt Medical, Inc., St. Louis, MO) and capsule endoscopy failed to reveal any other tumors. A diagnosis of primary hepatic signet ring cell neuroendocrine tumor was established. Ten months after surgery, the patient is well without any other detectable tumor on radiology. Serological neuroendocrine markers are also within normal limits. 相似文献

Many patients suffering from breast carcinoma have metastases at initial diagnosis. The common metastatic sites are skeleton, liver and lung. Metastases to stomach are rare and only three cases have been reported in Korea. The endoscopic features of gastric metastases from breast carcinoma can be divided into three main categories: diffuse infiltration, external compression, and localized tumor deposition with ulceration or with a polypoid mass. However, metastatic gastric lesions which resemble early gastric carcinoma are rare. Typically, gastric metastases are confined to submucosa and muscularis, so that mucosal biopsy specimens might be false-negative. We report a case of gastric metastasis from infiltrative lobular carcinoma of the breast in a 66-year-old woman who had undergone left mastectomy with postoperative radiotherapy 17 years earlier. Initial diagnosis was early gastric carcinoma, signet ring cell type on gastric biopsy findings. However, definitive diagnosis of metastatic breast cancer was confirmed after endoscopic mucosal resection of a presumed primary early gastric carcinoma. 相似文献

Breast cancer with stomach metastasis rare with an incidence of 1% or less among metastatic breast cancer patients. We experienced a case of breast cancer metastasizing to the stomach in 65-year-old female patient. She experienced dyspepsia and poor oral intake before visiting the clinic. Diffuse infiltration with nodular mucosal thickening of the stomach wall was observed, suggesting advanced gastric cancer based on gross endoscopic finding. Spread of poorly cohesive tumor cells in the gastric mucosa observed upon hematoxylin and eosin stain resembled signet ring cell carcinoma, but diffuse positive staining for GATA3 in immunohistochemical stain allowed for a conclusive diagnosis of breast cancer metastasizing to the stomach. Based on the final diagnosis, systemic chemotherapy was administered instead of primary surgical resection. After 2 cycles of docetaxel administration, she showed a partial response based on abdominal computed tomography scan. This case is an unusual presentation of breast cancer metastasizing to the gastrointestinal tract. 相似文献

Observation of a unique population of cells on a Wright-stained blood smear of a patient with metastatic breast carcinoma prompted a study to determine their origin. The primary carcinoma contained a marker, the presence of "signet cells." These were demonstrated in direct peripheral smears and buffy coat preparation of peripheral blood and confirmed histochemically by showing positive periodic acid-Schiff, alpha-napthol and beta-glucuronidase reactions. "Carcinocythemia" is suggested as a name for this unusual process observed over a six month period. Studies of the patient's immunocompetence, of circulating cell surface immunoglobulins and karyotype analysis were made. Postmortem examination revealed retroperitoneal fibrosis, splenic atrophy and extensive metastatic carcinoma but no evidence of leukemia. The cells will be contrasted to those seen in a second patient who appeared to have acute myelocytic leukemia complicating extensive cancer involving the bone marrow. The observations suggest that a leukemia-like blood picture due to circulating cancer cells may occur during the course of metastatic breast carcinoma. 相似文献
