1/492. coronavirus pneumonia following autologous bone marrow transplantation for breast cancer.infectious bronchitis virus, otherwise known as coronavirus, can cause mild upper respiratory tract illnesses in children and adults. Rarely has coronavirus been linked, either by serology or nasal wash, to pneumonia. We report a case of a young woman who, following treatment for stage IIIA breast cancer using a high-dose chemotherapy regimen followed by autologous bone marrow and stem cell transplantation, developed respiratory failure and was found to have coronavirus pneumonia as diagnosed by electron microscopy from BAL fluid. We propose that coronavirus should be considered in the differential diagnosis of acute respiratory failure in cancer patients who have undergone high-dose chemotherapy and autologous hematopoietic support.- - - - - - - - - - ranking = 1keywords = bone (Clic here for more details about this article) |
2/492. The CO 2 laser in mastectomy: a ten-year follow-up.We compared the healing process, postoperative course, and follow-up of patients who underwent modified radical mastectomy in the conventional way with those who underwent a laser procedure. Sixty women, aged 33 to 77 years, who suffered from carcinoma of the breast were randomly divided into two groups: Group 1: surgery was performed using scalpel and electrosurgery; Group 2: surgery was performed with a CO 2 Sharplan laser, skin-to-skin including the axilla dissection; maximal power, 40-60 W. The postoperative course was uneventful in both groups. wound healing was normal. sutures were removed on the tenth day. patients were followed at the Outpatient Clinic for 10 years. The circumference of the arm and forearm was measured at fixed points before surgery and at follow-up. mammography and liver and bone scans were performed every year. Four Group 1 patients developed swelling and edema of 2 to 3 cm at 6 to 8 months after surgery. Also two patients from subgroup A developed local recurrence. No edema or swelling or local recurrence could be detected in patients operated by laser. Surgery with laser is preferable to the conventional approach.- - - - - - - - - - ranking = 0.2keywords = bone (Clic here for more details about this article) |
3/492. Carcinoid tumours presenting as breast cancer: the utility of radionuclide imaging with 123I-MIBG and 111In-DTPA pentetreotide.Secondary tumours of any type in the breast are rare. A review of the literature demonstrated only 23 cases of carcinoid tumours with associated breast metastasis, as distinct from primary carcinoid tumours of the breast. Distant metastases from carcinoid tumours are correlated with poor prognosis and survival. Although both primary and metastatic mammary carcinoid tumours are uncommon, the recognition of the true origin of the tumours may be of importance owing to the different clinical management and prognosis of the two conditions. Recently, radionuclide-labelled imaging techniques have been applied to the localization of such lesions, based on isotope uptake by receptors present in these neuroendocrine tumours. We report two new cases of carcinoid tumours with breast metastases, the primaries being in the ileocaecal valve and the bronchus, respectively. The diagnosis of a carcinoid tumour was based on the clinical, biochemical, histopathological and immunostaining features. Furthermore, these patients had both 123I-MIBG and 111In pentetreotide scintigraphy performed. These radionuclides play a useful role in the localization and potentially in the management of carcinoid tumours and their distant metastases.- - - - - - - - - - ranking = 0.71358024691358keywords = endocrine (Clic here for more details about this article) |
4/492. Waldenstrom's macroglobulinaemia with Ig E M-component.A case of Waldenstrom's macroglobulinaemia with Ig E M-component was presented. A 76-year-old Japanese woman had a history of the operation for mammary carcinoma. Although neither lymphadenopathy nor hepatosplenomegaly was present, the immunohaematological findings typical for Waldenstrom's macroglobulinaemia were observed in this patient. Coexistence of the Ig M and Ig E M-components was recognized in the patient's serum protein. Positive reaction for FITC-conjugated anti-epsilon or rhodamine-conjugated anti-mu was noted in proliferating lymphoplasmacytic cells of the patient's bone marrow, but these reactions were not simultaneously observed in a single cell. The finding suggests that two separate populations of M-component-producing cells were present.- - - - - - - - - - ranking = 0.2keywords = bone (Clic here for more details about this article) |
5/492. Bone agent localization in hepatic metastases.We present the bone scintigrams of two patients, which demonstrate diffuse extraosseous uptake of a bone agent in metastatic masses in the liver, one from a primary lung tumor and one from a primary breast tumor. The bone imaging agent did not localize in the brain metastases in these patients. CTs of the abdomen in both patients showed massive metastases in the liver with multiple areas of tumor necrosis. The CT of the abdomen of the breast cancer patient showed multiple small hepatic calcifications. autopsy revealed massive tumor necrosis with calcifications in the enlarged liver. In routine bone scintigraphy, diffuse uptake of bone agents in the liver of a patient with a known malignancy should be considered suggestive of massive hepatic metastases.- - - - - - - - - - ranking = 1keywords = bone (Clic here for more details about this article) |
6/492. Selective delivery of doxorubicin to patients with breast carcinoma metastases by stealth liposomes.BACKGROUND: Stealth liposomes hold promise as a mode of delivering cytotoxic agents selectively to tumors in cancer patients. The objective of this study was to determine whether stealth liposomal doxorubicin accumulates selectively in bone metastases based on clinical material obtained from two patients with breast carcinoma. methods: Tumor tissue was obtained from two women (ages 33 years and 41 years, respectively) with metastatic breast carcinoma who responded to treatment with stealth liposomal doxorubicin and later underwent a surgical fixation procedure to treat a pathologic fracture of the femur. Drug levels in the tumor and adjacent muscle were examined by high performance liquid chromatography analysis in both patients and by fluorescence microscopy in one of the patients. RESULTS: Bone tumor fragments obtained during surgery performed 6 days after the administration of the 12th course of stealth liposomal doxorubicin in 1 patient and 12 days after the administration of the 16th course of stealth liposomal doxorubicin in the second patient had a 10-fold greater concentration of liposomal doxorubicin than tumor free muscle. doxorubicin fluorescence and specific nuclear staining showed good colocalization, thus confirming the presence of the liposome-delivered drug in the nuclei of tumor cells. CONCLUSIONS: Using skeletal muscle as a comparator, stealth liposomal doxorubicin accumulates selectively in metastatic breast carcinoma cells within bone.- - - - - - - - - - ranking = 0.4keywords = bone (Clic here for more details about this article) |
7/492. Lichenoid cutaneous drug reaction at injection sites of granulocyte colony-stimulating factor (Filgrastim).colony-stimulating factors are widely used for bone marrow recovery after chemotherapy. Various cutaneous side-effects have been described in most cases involving neutrophils. We report the first case of lichenoid reaction at injection sites of granulocyte colony-stimulating factor (G-CSF) in a 40-year-old patient treated for breast cancer. The eruption cleared after drug withdrawal, no recurrence was observed after drug replacement by granulocyte-macrophage colony-stimulating factor. Mainly lymphocyte-mediated lichenoid eruption to G-CSF was shown. Cutaneous side-effects to G-CSF do not share unequivocal pathogeny based on stimulation of neutrophils.- - - - - - - - - - ranking = 0.2keywords = bone (Clic here for more details about this article) |
8/492. breast cancer associated with Recklinghausen's disease: report of a case.A 49-year-old woman with Recklinghausen's disease presented to our department for investigation of a left breast lump, measuring 60 mm x 50 mm, which she had first noticed 6 months earlier, but had disregarded, believing it to be another manifestation of her Recklinghausen's disease. The lump was suspected to be malignant based on physical examination and ultrasonography. biopsy and frozen sections subsequently confirmed a diagnosis of scirrhous carcinoma. A standard radical mastectomy was performed, followed by postoperative chemoendocrine therapy. However, lungs, liver, and bone metastasis, as well as a contralateral breast tumor, developed and she died 4 months after surgery.- - - - - - - - - - ranking = 0.91358024691358keywords = endocrine, bone (Clic here for more details about this article) |
9/492. Clinics in diagnostic imaging (35). Metastases to the breasts, skin and bone.A 46-year-old woman presented with multiple skin lumps and right hip pain. Multiple nodules were palpable in the skin over the chest and abdominal wall, and in both breasts. Bilateral mammograms showed multiple solid masses, while ultrasound demonstrated multiple subcutaneous nodules. An osteolytic lesion was seen on the right hip radiograph. Excisional biopsy of a subcutaneous nodule revealed metastatic adenocarcinoma. The diagnosis of metastases to the breast is discussed, together with imaging features of other multiple breast lesions, such as fibroadenomas and cysts.- - - - - - - - - - ranking = 0.8keywords = bone (Clic here for more details about this article) |
10/492. Multifocal bone tuberculosis presenting as a breast mass: CT and MRI findings.Chest wall involvement is an uncommon manifestation of musculoskeletal tuberculosis. We present computed tomography and magnetic resonance imaging findings in a case with multifocal musculoskeletal tuberculosis presenting as a breast mass. These radiological modalities are not diagnostic without histopathological confirmation, but they are valuable guides to surgery in defining the extent of disease involvement.- - - - - - - - - - ranking = 0.8keywords = bone (Clic here for more details about this article) |
