Myasthenia Gravis Complicated with Peripheral T-cell Lymphoma, Not Otherwise Specified (PTCL-NOS), Following Thymectomy and Longstanding Tacrolimus Therapy
نویسندگان
چکیده
Myasthenia gravis (MG), a neuromuscular junction autoimmune disease, sometimes complicates second malignancies; however, T-cell lymphoproliferative disorders have rarely been reported. A 55-year-old man, who received oral tacrolimus and prednisolone for MG for 16 years after thymectomy, presented with left abdominal pain, lymphadenopathy, and splenomegaly. A lymph node biopsy revealed peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS). This is the first report of oral tacrolimus leading to a T-cell lymphoproliferative disorder in patient without a history of transplantation. Physicians should be aware of the possibility of rare T-cell lymphoproliferative disorders, such as PTCL-NOS, occurring as complications in MG patients on immunosuppressive regimens after thymectomy.

[Peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS)].
Peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS) is a heterogeneous category of nodal and extranodal mature T-cell lymphomas. PTCL-NOS is a highly aggressive lymphoma, and its prognosis is poorer than those of aggressive B-cell lymphoma such as diffuse large B-cell lymphoma(DLBCL). Current standard chemotherapies for aggressive B-cell lymphoma, such as CHOP, are the commonly used ...
متن کاملPeripheral T-Cell Lymphoma of the Submandibular Salivary Gland as an Unusual Manifestation of Richter's Syndrome: A Case Report and Literature Review
Richter's syndrome is the development of high-grade non-Hodgkin lymphoma (NHL) or Hodgkin lymphoma in patients with chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL). In most patients with Richter's syndrome, the high-grade NHL is diffuse large B-cell lymphoma. Only a small minority of CLL/SLL patients develop T-cell malignancies. Herein, we describe a 40-year-old male patient...
متن کاملThe association of nm23-H1 expression with a poor prognosis in patients with peripheral T-cell lymphoma, not otherwise specified.
nm23-H1 was originally identified as a protein that is expressed at a lower than usual level in metastatic cancer cells. The nm23 genes play critical roles in cellular proliferation, differentiation, oncogenesis, and tumor metastasis. Peripheral T-cell lymphoma (PTCL) is relatively rare, accounting for only 10% to 15% of non-Hodgkin's lymphomas. We examined whether nm23-H1 is a prognostic facto...
متن کاملTranscript profiling in peripheral T-cell lymphoma, not otherwise specified, and diffuse large B-cell lymphoma identifies distinct tumor profile signatures.
To glean biological differences and similarities of peripheral T-cell lymphoma-not otherwise specified [PTCL-NOS] to diffuse large B-cell lymphoma (DLBCL), a transcriptosome analysis was done on five PTCL-NOS and four DLBCL patients and validated by quantitative real-time reverse transcription-PCR on 10 selected genes. Normal peripheral blood T cells, peripheral blood B cells, and lymph node we...
متن کاملIdentification of multiple subclones in peripheral T-cell lymphoma, not otherwise specified with genomic aberrations
Peripheral T-cell lymphoma, not otherwise specified (PTCL, NOS) with genomic aberrations has been shown to resemble lymphoma-type adult T-cell leukemia/lymphoma (ATLL) in terms of its genomic aberration patterns, histopathology, and prognosis. We have shown recently that a majority of patients with acute-type ATLL have multiple subclones that were likely produced in lymph nodes. In this study, ...
