Primary cutaneous lymphomas are a heterogeneous group of malignancies, exhibiting clinical differences from the systemic lymphomas. Peripheral T-cell lymphomas not uncommonly involve the skin, either as primary or secondary manifestation of the disease. Within this group, three rare provisional entities are delineated in the WHO-EORTC classification for cutaneous lymphomas. We present an extrem...

Two children with cutaneous convoluted lymphoblastic lymphoma are reported. Malignant cells from both patients contained cytoplasmic Mu heavy chains characteristic of pre-B-cells and expressed CALLA and la antigens as well. Most cases of convoluted lymphoblastic lymphoma are T-cell-derived neoplasms. The non-T, non-B phenotype found in these two children demonstrates that histology does not nec...

Cutaneous T-cell lymphomas are disfiguring malignant lymphoproliferative disorders for which standard therapy has been principally palliative. 2-Chlorodeoxyadenosine (2-CdA), a new purine analogue resistant to degradation by adenosine deaminase that has substantial activity against lymphoid neoplasms, was administered to 16 patients with cutaneous involvement by T-cell lymphoma. All patients ha...

Histone deacetylase inhibitors (HDAC-Is) are agents that have demonstrated anticancer activity in vivo and in vitro, leading to clinical trials evaluating their efficacy in multiple cancer types. Only two HDAC-Is are currently approved by the U.S. Food and Drug Administration, vorinostat and romidepsin, both with indications for cutaneous T-cell lymphoma. Romidepsin has an additional approval i...

NPM-ALK chimeric transcripts, encoded by the t(2;5), lead to an aberrant expression of ALK by CD30+ systemic lymphomas. To determine if t(2;5) is involved in cutaneous lymphoproliferative disorders, we studied 37 CD30+ cutaneous lymphoproliferations, 27 mycosis fungoides (MF), and 16 benign inflammatory disorders (BID). NPM-ALK transcripts were detected by nested reverse transcription-polymeras...

Abstract Introduction: Extra-nodal exposition of T-cell non-hodgkin lymphoma (NHL) is extremely rare, and is frequently observed in patients with immune system dysfunction. Peripheral T-cell lymphoma does not express CD56 is rare. Malignant lymphoma of the uvula is exceedingly unusual. The current study reported a case of peripheral T-cell lymphoma of the uvula in an immunecompetent patient. ...

Forty-one cases of T cell lymphoma were identified on the basis of morphology and the expression of two or more T cell antigens with an absence of B cell markers. Mycosis fungoides and lymphoblastic lymphoma were excluded. Marked clinical, morphological, and immunologic diversity was observed. Cutaneous lymphoma was found in approximately 50% of the patient group, and 27% had a prior history of...

Histone deacetylase (HDAC) inhibitors represent a novel class of medication that is being targeted for use in the treatment of cancer. A member of this class, vorinostat, has recently been approved for the therapy of cutaneous T-cell lymphoma. Importantly, emerging data from animal studies have indicated that HDAC inhibitors may have the capacity to potently suppress the development of autoimmu...
