Background: Pleomorphic xanthoastrocytoma (PXA) is usually considered a relatively benign and localized entity. However, cases of PXA with anaplastic features have been reported in recent years. Anaplastic pleomorphic xanthoastrocytoma has been added to the 2016 WHO classification of CNS tumors as a distinct entity. Case presentation: We describe a rare case of PXA with dissemination, both at t...

The lectins Peanut agglutinin (PNA), Canavalia ensiformis (Con A), Ulex europaeus-1 (UEA-1), Dolichos biflorus (DBA), Triticum vulgaris (WGA) were studied in a series of 36 meningiomas (16 meningotheliomatous-including 3 recurrences, 7 transitional, 4 angiomatous, 2 "hemangiopericytic", 3 papillary-including 1 recurrence, 4 anaplastic-including 3 recurrences. PNA binds to all cases of meningoth...

OBJECTIVE To show the main findings for anaplastic ependymoma on MRI. MATERIAL AND METHODS We reviewed all patients diagnosed with anaplastic ependymoma at our tertiary hospital during a six-year period. We recorded the MRI findings for this type of tumor (on conventional sequences following the protocol for the study of CNS tumors, diffusion-weighted imaging, contrast-enhanced sequences, and...

Anaplastic large cell lymphoma (ALCL) is the second most common type of peripheral T and an aggressive mature lymphoma. About 50 to 70% systemic ALCLs are anaplastic kinase positive (ALK +), proportion even higher in pediatric population. The 5-year survival after chemotherapy around 70 80%. But there a subgroup ALK+ ALCL patients who refractory chemotherapy. Brentuximab vedotin approved agent ...

Anaplastic thyroid carcinoma is an uncommon, highly aggressive malignancy usually presenting in the elderly. An eighteen year old boy was recently diagnosed as anaplastic carcinoma of the thyroid. PET/CECT scan performed for staging, revealed a large FDG avid heterogeneously enhancing thyroid mass with bilateral jugular venous thrombosis, which also showed increased FDG uptake, thus pointing to...

Anaplastic large cell lymphoma is a rare disease associated with breast implants. We present the case of a woman who had had breast augmentation and multiple revisions over a period of 13 years and presented with recurrent fluid collections. The cause was determined to be anaplastic large cell lymphoma, which required removal of the implants, capsulectomy, and evaluation by a medical oncologist...

New therapeutic approaches are mandatory for anaplastic thyroid cancer. We investigated the ability of a new combined treatment using valproic acid (VPA), the only clinically available histone deacetylase inhibitor, and the tyrosine-kinase inhibitor imatinib mesylate to control the cell growth of anaplastic thyroid cancer cell lines. We showed that treatment with imatinib alone is unable to aff...

The anaplastic large cell lymphoma is a rare entity in pediatric patients. We present an unusual case of pericardial involvement, quite uncommon as extranodal presentation of this type of disorder, that provoked a life-risk situation requiring an urgent pericardiocentesis. To our knowledge, this is the first report on a child with pericardial involvement without an associated cardiac mass secon...

BACKGROUND Because anaplastic thyroid cancer is a rare malignancy with a high mortality rate, the benefit of multimodality treatment was evaluated. METHODS Overall survival was determined in the 2742 patients captured by the National Cancer Database who were diagnosed with anaplastic thyroid cancer between 1998 and 2008. Kaplan-Meier analysis and then Cox proportional hazard regression was pe...
