We studied natural killer (NK) activity and lymphocyte subsets in 11 active parenteral heroin abusers, 11 long-term methadone-maintained former heroin abusers and 11 apparently healthy individuals. All subjects were males aged 23 to 49 and none had active infectious or inflammatory diseases. All current or former heroin abusers were seronegative for(More)
Angiographic diagnosis of an intracerebral aneurysm in a neonate was made on the 13th day of life following persistent neurological symptoms that began at birth. Rupture of the aneurysm probably occurred within the first day of life. This unusual condition should be considered in newborn infants with unexplained neurological signs or intracranial hemorrhage.
Vein tumors are rare, difficult to diagnose, and usually malignant. We have encountered three: a leiomyoma of the jugular vein and leiomyosarcomas of the saphenous vein and inferior vena cava (IVC). The leiomyoma was lost to follow-up, the saphenous vein leiomyosarcoma survived nine years, and the leiomyosarcoma of the IVC is six months without recurrence.(More)
We report a case of a malignant peripheral nerve sheath tumor arising from a retroperitoneal ganglioneuroma in an adult male. There was no known previous history of a childhood neuroblastoma or of radiation therapy. In addition, the patient had no stigmata or family history of von Recklinghausen's neurofibromatosis. This case provides evidence that,(More)
The case of a 65-year-old man who had a gastric tumor with components of choriocarcinoma and yolk sac tumor is presented. The presence of a small component of adenocarcinoma in the primary tumor and the absence of any gonadal or other primary tumor at autopsy confirm its origin. Despite the common association of embryonal and trophoblastic elements in(More)
Most cases of intravascular large cell lymphoma are of B-cell phenotype, with a few cases of T-cell lineage and rare cases with histiocytic features described. A definitive natural killer (NK) cell variant has not been recognized. This report is the first to describe the clinical, histologic, immunophenotypic, and molecular features of 2 cases of(More)
The reactivity of the anti-Leu-7 monoclonal antibody was tested in 39 neoplastic and nonneoplastic thyroid tissue specimens. These included eight colloid goiters, 14 follicular adenomas, nine papillary carcinomas, five follicular carcinomas, two medullary carcinomas, and one metastatic follicular carcinoma in bone. We observed strong cytoplasmic and/or cell(More)
A 9-year-old boy is presented who was antibody positive for human immunodeficiency virus (HIV) and who had recurrent episodes of gross hematuria. Renal biopsy revealed findings typical of IgA nephropathy but also showed electron-microscopic abnormalities seen with HIV-associated nephropathy. In addition, IgA antibodies to multiple HIV proteins were detected(More)
The lesions known as lymphocytic vasculitis, polymorphic reticulosis (midline malignant reticulosis, lethal midline granuloma), lymphomatoid granulomatosis, and angiocentric lymphoma form what have been collectively termed the angiocentric immunoproliferative lesions (AIL). Because of recent reports demonstrating clonal rearrangements of the T-cell receptor(More)
A 17-year-old black woman with a large vesical pheochromocytoma was managed successfully by hemicystectomy and ureteroneocystotomy. Preoperatively, in addition to the routine diagnostic evaluation, magnetic resonance imaging was performed. Magnetic resonance imaging proved to be an extremely useful modality to assess the integrity of the bladder wall and(More)
