Enormous hemangiosarcoma of the heart
1994
This report describes a 26-year-old patient with hemangiosarcoma of the heart and summarizes the clinicopathological features in previous reports of patients with cardiac angiosarcoma. The patient was admitted to our hospital because of a syncope and one episode of nocturnal dyspnea and hemoptysis. In his history he complained of progressive weakness and loss of weight over the past 2 months. Echocardiography and computed tomography of the chest showed inhomogeneous masses in the pericardial cavity completely surrounding the heart and involving the ascending aorta and the superior vena cava. Histological examination of the tissue obtained from the mass by fine needle technique revealed a po…
Spontaneous regression of multiple melanocytic nevi after melanoma: report of 3 cases.
2014
Complete spontaneous regression of multiple melanocytic nevi after melanoma is an extremely rare phenomenon. We report 3 cases of patients with a history of melanoma that showed regression of almost all melanocytic nevi over time. One of the patients had 2 simultaneous primary cutaneous melanomas without metastasis. In the other 2 patients, regression of the melanocytic nevi was seen after the development of metastasis in lymph nodes. These patients had spontaneously developed an efficient immune response against melanocytes, and they would represent paradigmatic examples of the spontaneous immune responses in melanoma patients. Better understanding of the mechanisms involved in the complet…
Postmortem distribution of dihydrocodeine and metabolites in a fatal case of dihydrocodeine intoxication.
1998
A report of a fatal dihydrocodeine ingestion under substitution therapy is given. Quantitation of dihydrocodeine, dihydromorphine, N-nordihydrocodeine, dihydrocodeine-6-, dihydromorphine-6- and dihydromorphine-3-glucuronide was performed simultaneously after solid-phase extraction prior to HPLC analysis, and the analytes were detected using their native fluorescence. Postmortem concentrations of blood samples from different sampling sites as well as from liver, kidney and cerebrum are reported. A hair sample was investigated to prove long-term use of the substitute drug. Site-to-site differences of the analytes from blood samples were very small. The partition behavior of the opioid glucuro…
Fatal sepsis due to mycobacterium tuberculosis after allogeneic bone marrow transplantation.
2001
Mycobacterium tuberculosis is a serious, but rare infectious complication after allogeneic bone marrow transplantation. We describe a case of fatal sepsis due to Mycobacterium tuberculosis after allogeneic bone marrow transplantation for Philadelphia chromosome-positive ALL. The diagnosis was made after BAL. Although broad-spectrum antituberculous therapy was started immediately after diagnosis, blood cultures became positive for Mycobacterium tuberculosis. The patient developed severe pyrexias and finally died of multi-organ failure. Rapid progression of mycobacterial infection should be considered in patients post BMT with unexplained fever, particularly in patients from endemic areas.
Testicular fusocellular rhabdomyosarcoma as a metastasis of elbow sclerosing rhabdomyosarcoma: A clinicopathologic, immunohistochemical and molecular…
2010
Abstract Sclerosing rhabdomyosarcoma (SRMS) is an infrequent variant of rhabdomyosarcoma characterized by extensive intercellular hyaline fibrosis. We report the case of a 37 year-old male with a 9 × 6 cm SRMS on the right elbow. Histologically, the tumor showed an abundant extracellular hyaline matrix with extratumoral vascular emboli and microscopic foci of fusocellular embryonal rhabdomyosarcoma (FRMS) separated by a fibrotic band from the sclerosing areas. One year later the patient presented with a right intratesticular tumor of 1.2 × 0.8 cm, which was reported as pure FRMS. Immunohistochemically, SRMS was positive only for MyoD1 and Vimentin and negative for Myogenin and Desmin. Both …
Atypical Pleomorphic Extraosseous Ewing Tumor/Peripheral Primitive Neuroectodermal Tumor with Unusual Phenotypic/Genotypic Profile
2002
A pleomorphic undifferentiated tumor primarily located in the retroperitoneum with a phenotype compatible with an extraosseous Ewing tumor/peripheral primitive neuroectodermal tumor (ET/pPNET) pattern and unusual molecular features is described. Immunohistochemically, HBA-71 (CD99/mic2) and several neural markers were intensively expressed together with scattered cells expressing carcinoembryonic antigen (CEA). Short-term culture showed biphasic neuroblastic and epithelioid cell populations, with the latter expressing germ cell markers (CEA, alpha-fetoprotein, and the beta-subunit of chorionic gonadotrophin). Conventional cytogenetics displayed several chromosomic rearrangements, especially…
Ewing-like sarcoma with CIC-DUX4 gene fusion in a patient with neurofibromatosis type 1. A hitherto unreported association.
2015
Sarcoma with CIC-DUX4 gene fusion is emerging as the most prevalent subset of Ewing-like undifferentiated small round cell sarcomas with around 50 cases published. We report hereby the case of a 40-year-old male who presented a CIC-DUX4 sarcoma in deep soft tissues in his thigh. He had been diagnosed with neurofibromatosis type 1 at age 19 and over the years underwent resection of multiple neural neoplasms, including two malignant peripheral nerve sheath tumors with classical spindle-cell histopathology. The CIC-DUX4 sarcoma was treated with surgical resection, radiation and chemotherapy, but lung and brain metastases developed and the patient died from the disease 14 months after diagnosis…
Malignant peripheral neuroectodermal tumors in urology.
1995
During the past few years, a new tumor type has emerged in the pediatric and adolescent group of cancer patients, which has been designated malignant peripheral neuroectodermal tumor (MPNT). This tumor has some clinical and pathological signs in common with either soft-tissue sarcomas or classic Ewing's sarcoma, but is defined as a distinct entity because of its immunohistological characteristics. The tumor expresses neuronal markers, but the pattern varies: chromogranin, neuron-specific enolase, synaptophysin, protein S-100 and others. MPNT can occur in the urogenital region. The differential diagnosis on clinical grounds must include Ewing's and soft tissue sarcomas, and also Wilms' tumor…
Failure of sustained engraftment after non-myeloablative conditioning with low-dose TBI and T cell-reduced allogeneic peripheral stem cell transplant…
2001
We investigated whether a T cell-reduced allogeneic stem cell transplant (SCT) with minimal conditioning and subsequent donor lymphocyte infusions (DLI) could reduce the incidence and severity of GVHD while retaining stable engraftment. Five patients with hematological malignancies (three MM, one CLL, one Chediak-Higashi syndrome) were conditioned with TBI (200 cGy). One patient additionally received fludarabine (120 mg/m(2)). CsA and mofetyl-mycophenolate (MMF) were administered to prevent GVHD. All patients were grafted with >3 x 10(6)/kg highly purified CD34(+) cells together with 2 x 10(6)/kg CD3(+) cells (three patients) or 1 x 10(5)/kg CD3(+) cells (two patients). Quick hematopoietic …
Traumatic lesion of the extracranial vertebral artery--a note-worthy potentially lethal injury.
1994
The autopsy findings from routine neuropathological investigations of the cervical spine after any history of trauma emphasized the vulnerability of the extracranial vertebral arteries. In 21 cases with trauma to the head and neck, normal autopsy procedures did not succeed in revealing an obvious cause of death. Traumatic lesions of the spinal cord such as contusion or neurorrhexis were seen in 10 cases. In 15 cases we observed different degrees and stages of traumatic lesions of the extracranial vertebral arteries. Sudden death due to acute brain stem ischemia might be considered as an explanation in some of these cases. Six case reports with traumatic vertebral artery (VA) lesions after s…
