Progressive peripheral CD8 T lymphocytosis complicated by pure red cell aplasia following immunosuppressive therapy for thymoma-associated myasthenia gravis.

We herein report a unique case of type B2 thymoma-associated myasthenia gravis which was ameliorated by immunosuppressive therapy in combination with chemotherapy. However, the patient subsequently developed pure red cell aplasia and marked lymphocytosis after additional chemotherapy aimed at improvement of thymoma. While a separate immunosuppressive regimen was effective for anemia, lymphocytosis was exacerbated. The biopsied thymoma specimen contained CD4, CD8, and CD4/CD8 T cells, some of which were CD3,...

Ectopic hamartomatous thymoma (biphenotypic branchioma): A case report and review of the literature.

Ectopic hamartomatous thymoma is a very rare soft tissue neoplasm that commonly occurs in the lower neck of adult men.

A Phase II Study of Pemetrexed in Patients with Recurrent Thymoma and Thymic Carcinoma.

Thymoma and thymic carcinoma are neoplastic diseases with reported chemosensitivity to a broad range of agents. However, due to the rarity of these diseases, few prospective trials have been conducted in patients with advanced thymic malignancies. We conducted a prospective phase II trial to evaluate the clinical activity of pemetrexed, a multi-targeted anti-folate agent, in previously treated patients with thymoma (THY) and thymic carcinoma (TC).

Comparing robotic and trans-sternal thymectomy for early-stage thymoma: a propensity score-matching study.

Minimally invasive techniques seem to be promising alternatives to open approaches in the surgical treatment of early-stage thymoma, although there are controversies because of lack of data on long-term results. The aim of the study was to evaluate the surgical and oncological results after robotic thymectomy for early-stage thymoma compared to median sternotomy.

Long-term outcomes of advanced thymoma in patients undergoing preoperative chemotherapy or chemoradiotherapy followed by surgery: a 20-year experience.

The results of preoperative chemotherapy or chemoradiotherapy followed by surgery for locally advanced thymoma were analysed.

Clinicopathological Features of Thymoma with the Expression of Programmed Death-Ligand 1.

Programmed death-ligand 1 (PD-L1) is reportedly expressed in various malignancies and is considered a prognostic factor. We attempted to reveal the usefulness of the PD-L1 expression as a prognostic factor in patients with thymoma.

False-Positive Results in 18F-Fluorocholine PET/CT for a Thymoma in Workup of a Hereditary Primary Hyperparathyroidism.

We present the case of a severe familial primary hyperparathyroidism related to a germline deletion in the HRPT2 (CDC73) gene. Morphological explorations revealed 2 potential hyperfunctioning parathyroid glands: a left cervical lesion on the neck ultrasound, and an ectopic mediastinal lesion on the parathyroid scintigraphy using Tc-methoxyisobutylisonitrile and on F-fluorocholine PET/CT. Surgery removal and histopathological examination determined that the mediastinal mass corresponded to a thymoma and the ...

Aplastic Anemia as an Immune-mediated Complication of Thymoma: A Case Report.

Thymomas are the most common masses located in the anterior mediastinum, and they are often associated with autoimmune disorders including myasthenia gravis, polymyositis, and aplastic anemia (AA). Autoreactive T-cell clones generated by the thymoma may lead to autoimmune disorders. We report the case of a 14-year-old boy who was examined for AA, and the underlying cause was determined to be an immune-mediated complication of thymoma. He had no matched sibling donors. He underwent thymectomy, and 3 months l...

Respiratory insufficiency from myasthenia gravis and polymyositis due to malignant thymoma triggering Takotsubo syndrome.

Takotsubo syndrome (TTS) is a non-ischemic cardiomyopathy with sudden but transient systolic dysfunction. TTS mimics myocardial infarction clinically, chemically, and electrocardiographically but echocardiography typically shows apical ballooning and coronary angiography is normal. TTS has not been reported in a patient with myasthenia gravis (MG) and polymyositis due to a malignant thymoma.

Clinical & laboratory features of seventy-eight UK patients with Good's syndrome (thymoma & hypogammaglobulinemia).

Good's syndrome (thymoma and hypogammaglobulinemia) is a rare secondary immunodeficiency disease, previously reported in the published literature as mainly individual cases or small case series. We use the national UK-Primary Immune Deficiency (UKPID) registry to identify a large cohort of patients in the UK with this PID to review its clinical course, natural history and prognosis. Clinical information, laboratory data, treatment and outcome were collated and analysed. Seventy-eight patients with a median ...

Selected Case From the Arkadi M. Rywlin International Pathology Slide Seminar: Atypical Thymoma With Rhabdomyomatous Differentiation.

Thymic epithelial neoplasms with foci of rhabdomyomatous differentiation are rare. A case is presented of a primary thymic epithelial neoplasm showing the features of an atypical spindle cell thymoma that contained foci of bland-appearing rhabdomyomatous cells. The histologic and immunohistochemical features of this tumor are discussed along with a review of the literature and the comments from the AMR members to the case.

Expression patterns, prognostic value, and intratumoral heterogeneity of PD-L1 and PD-1 in thymoma and thymic carcinoma.

Thymic epithelial tumors (TET) including thymoma and thymic carcinoma are rare tumors with little data available to guide treatment. Immunotherapy with checkpoint blockade has shown promising activity, but data regarding the expression patterns and prognostic implications of programmed death 1 (PD-1) and its ligand (PD-L1) in TET have yielded conflicting results. Intratumoral heterogeneity of PD-1/L1 expression has been demonstrated in other cancers but has not been described in the TET literature.

Prevention of infectious diseases in patients with Good syndrome.

Good syndrome is a profoundly immunocompromising condition with heterogeneous immune deficits characterized by the presence of thymoma, low-to-absent B-lymphocyte counts, hypogammaglobulinemia, and impaired cell-mediated immunity. Opportunistic infectious diseases associated with Good syndrome represent a diagnostic and therapeutic challenge, given their protean clinical manifestations. Although these infectious complications have been reviewed in prior publications, recommendations regarding their preventi...

Cytoreductive Pleurectomy and Intra Thoracic Chemo Hyperthermia for Pleural Relapse of Thymomas.

Several surgical procedures, from debulking to extra pleural pneumonectomy, may be applied for stage IVa Masaoka thymomas but their efficiency is still controversial. Case studies favored R resection as the cornerstone of multimodal therapy for loco-regional metastatic extension. We report our standardized procedure associating cytoreductive surgery and intra thoracic chemo hyperthermia on a 46-years old patient presenting B2 thymoma and synchronous unilateral pleural metastasis.
