Utility of ALK-1 protein expression and ALK rearrangements in distinguishing inflammatory myofibroblastic tumor from malignant spindle cell lesions of the urinary bladderWilliam R Sukov
Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN 55902, USA
Mod Pathol 20:592-603. 2007....- A survey of clusterin and fascin expression in sarcomas and spindle cell neoplasms: strong clusterin immunostaining is highly specific for follicular dendritic cell tumorKaren L Grogg
Division of Anatomic Pathology, Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN 55905, USA
Mod Pathol 18:260-6. 2005..Rare cases of leiomyosarcoma, fibrosarcoma and angiosarcoma may show strong clusterin staining. Fascin staining was very nonspecific among spindle cell tumors and thus does not imply a dendritic cell lineage... - Expression of CXCL13, a chemokine highly upregulated in germinal center T-helper cells, distinguishes angioimmunoblastic T-cell lymphoma from peripheral T-cell lymphoma, unspecifiedKaren L Grogg
Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN 55905, USA
Mod Pathol 19:1101-7. 2006..Given its specificity when compared to cases of peripheral T-cell lymphoma, unspecified as well as paracortical lymphoid hyperplasia, it may be a useful marker in the diagnosis of angioimmunoblastic T-cell lymphoma... - Spectrum of bone marrow findings in patients with angioimmunoblastic T-cell lymphomaKaren L Grogg
Department of Laboratory Medicine and Pathology, Mayo Clinic, 200 First Street SW, Rochester, MN 55905, USA
Br J Haematol 137:416-22. 2007..In two cases, these changes obscured the presence of BM involvement by AITL. The spectrum of BM findings in AITL patients is important to recognise for early and accurate diagnosis in this disease... 
Primary cutaneous CD4-positive small/medium-sized pleomorphic T-cell lymphoma: a clonal T-cell lymphoproliferative disorder with indolent behaviorKaren L Grogg
Department of Laboratory Medicine and Pathology, Division of Anatomic Pathology, Mayo Clinic, Rochester, MN 55905, USA
Mod Pathol 21:708-15. 2008..In patients with isolated cutaneous lesions, the indolent behavior of this rare T-cell neoplasm should be recognized to avoid unnecessary treatment...- Clusterin expression distinguishes follicular dendritic cell tumors from other dendritic cell neoplasms: report of a novel follicular dendritic cell marker and clinicopathologic data on 12 additional follicular dendritic cell tumors and 6 additional interKaren L Grogg
Division of Anatomic Pathology, Department of Laboratory Medicine and Pathology, Mayo Clinic, 200 First Street SW, Rochester, MN 55905, USA
Am J Surg Pathol 28:988-98. 2004..Thus, staining for clusterin is useful in classification of dendritic cell tumors, particularly when the more common markers of follicular dendritic cells are not expressed... - Incidence of TCR and TCL1 gene translocations and isochromosome 7q in peripheral T-cell lymphomas using fluorescence in situ hybridizationAndrew L Feldman
Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN 55905, USA
Am J Clin Pathol 130:178-85. 2008..One of the latter cases also had a translocation of TCRA, and further studies confirmed a novel t(5;14) translocation... - Clinicopathologic features of B-Cell lineage neoplasms with aberrant expression of CD3: a study of 21 casesJennifer L Oliveira
Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN 55905, USA
Am J Surg Pathol 36:1364-70. 2012..As these neoplasms often lack typical expression of B-cell antigens, knowledge of these features will help avoid misclassification... - Clusterin is expressed in normal synoviocytes and in tenosynovial giant cell tumors of localized and diffuse types: diagnostic and histogenetic implicationsJennifer M Boland
Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN 55905, USA
Am J Surg Pathol 33:1225-9. 2009..The observed staining patterns provide evidence linking the large mononuclear cells with normal synoviocytes and support that tenosynovial giant cell tumors are neoplasms showing synovial differentiation... - Nodular Pulmonary Amyloidosis Is Characterized by Localized Immunoglobulin Deposition and Is Frequently Associated With an Indolent B-cell Lymphoproliferative DisorderKaren L Grogg
Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN
Am J Surg Pathol 37:406-12. 2013..The association of nodular pulmonary amyloidoma with autoimmune disease and lymphoma indicate the majority of these lesions relate to an underlying lymphoplasmacytic neoplasm in the spectrum of MALT lymphoma... - CD33 detection by immunohistochemistry in paraffin-embedded tissues: a new antibody shows excellent specificity and sensitivity for cells of myelomonocytic lineageJames D Hoyer
Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN 55905, USA
Am J Clin Pathol 129:316-23. 2008..The CD33 antibody was also found to be a useful marker in the workup of myeloid sarcomas. This anti-CD33 antibody will be a useful marker in the workup of acute leukemias and myeloid sarcomas on paraffin-embedded tissue samples... 
Angioimmunoblastic T-cell lymphoma: a neoplasm of germinal-center T-helper cells?Karen L Grogg
