BACKGROUND: Combined thymic carcinoma is a malignant neoplasm of the thymus recently added to the 4th edition of the World Health Organization (WHO) classification of tumors of the lung, pleura, thymus and heart. It involves at least one type of thymic carcinoma and another thymic epithelial tumor. The previously used term "combined thymic epithelial tumor" has been abandoned. CASE PRESENTATION: Here, we present an unusual case of combined thymic carcinoma of the thymus in a 44-year-old male who had suffered from fever, chest pain, chest tightness and shortness of breath...

We report a case of metastatic thymic carcinoma which presented as an enhancing mass located in the neural foramen of the thoracic spine. More common tumours which arise in the neural foramen would include a neurogenic tumour or developmental anomalies such as a foregut duplication cyst. This case is singular firstly because the lesion present as radiculopathy which mimics a neurogenic tumour. Secondly, the presentation was unusually delayed as the patient presented to our centre more than a decade after the resection of the primary tumour in another institution...

Primary thymic adenocarcinoma is an extraordinarily rare malignancy; only 49 cases have been reported in the medical literature to date. Because of its rarity, clinical and pathologic characteristics of thymic adenocarcinoma are unclear. We present nine cases of primary thymic adenocarcinoma and discuss clinicopathologic findings in the context of the existing literature. Two-hundred twenty-six thymic carcinoma cases were diagnosed at Samsung Medical Center in Korea, from January, 2001 to July, 2016. Nine of these 226 cases were primary thymic adenocarcinomas...

We report a case of Masaoka stage IVb thymic carcinoma that had metastasized to right supraclavicular lymph nodes, where it would have been difficult to achieve complete resection. Thus, we performed concurrent chemoradiotherapy, which decreased the tumor's size and facilitated complete resection. The patient had an uneventful postoperative course and 30 months of recurrence-free survival. Concurrent chemoradiotherapy followed by complete surgical resection may be a useful strategy in cases of stage IVb thymic carcinoma with supraclavicular lymph node metastasis...

Most anterior mediastinal tumors are thymomas. Thymic metastasis from other primary cancers is extremely rare. We report the case of a 72-year-old man who developed thymic and mediastinal lymph node metastases of cecum cancer. He had undergone laparoscopic ileocecal resection with regional lymph node dissection for primary cecum cancer 15 months previously. Follow-up computed tomography revealed tumors in the anterior mediastinum. Fluorodeoxyglucose positron emission tomography showed positive uptake in the tumors...

OBJECTIVES: The T descriptor of thymic epithelial tumours proposed by the International Association for the Study of Lung Cancer and the International Thymic Malignancy Interest Group as well as the Masaoka-Koga system is defined by the anatomical extent of primary tumours, regardless of their size. However, the prognostic significance of tumour size in thymic epithelial tumours has not been fully elucidated. METHODS: We evaluated the prognostic significance of tumour size in 154 consecutive patients with thymic epithelial tumours including 124 thymomas, 21 thymic carcinomas and 9 neuroendocrine tumours, who underwent complete resection between 2001 and 2014...

Therapeutic options to cure advanced, recurrent, and unresectable thymomas are limited. The most important factor for long-term survival of thymoma patients is complete resection (R0) of the tumor. We therefore evaluated the response to and the induction of resectability of primarily or locally recurrent unresectable thymomas and thymic carcinomas by octreotide Long-Acting Release (LAR) plus prednisone therapy in patients with positive octreotide scans. In this open label, single-arm phase II study, 17 patients with thymomas considered unresectable or locally recurrent thymoma (n = 15) and thymic carcinoma (n = 2) at Masaoka stage III were enrolled...

Thymic carcinoma is a rare type of cancer that is more aggressive and is associated with a poorer prognosis compared with thymoma. No definitive clinical management of this disease has been established to date. This report describes the 20-year clinical course of a 50-year-old male patient who was successfully treated for initially diagnosed stage IVb thymic carcinoma. Thymo-thymectomy combined with resection of the surrounding organs was performed on December 1995 with curative intent (R0) after neoadjuvant chemoradiotherapy...

BACKGROUND: Actinic keratosis is a precursor to cutaneous squamous cell carcinoma. Long treatment durations and severe side effects have limited the efficacy of current actinic keratosis treatments. Thymic stromal lymphopoietin (TSLP) is an epithelium-derived cytokine that induces a robust antitumor immunity in barrier-defective skin. Here, we investigated the efficacy of calcipotriol, a topical TSLP inducer, in combination with 5-fluorouracil (5-FU) as an immunotherapy for actinic keratosis...

Sarcomatoid carcinoma of the thymus is extremely rare. An operation remains the only effective treatment for this disease. We report a case of complete resection of thymic sarcomatoid carcinoma through a total aortic arch replacement and left upper lobectomy at our institution. Our aggressive operation was very effective, and the patient has experienced no recurrence in the 3 years since his operation.

Thymoma and thymic carcinoma are thymic epithelial tumors (TETs). We performed a molecular profiling to investigate the pathogenesis of TETs and identify novel targets for therapy. We analyzed 37 thymomas (18 type A, 19 type B3) and 35 thymic carcinomas. The sequencing of 50 genes detected nonsynonymous mutations in 16 carcinomas affecting ALK, ATM, CDKN2A, ERBB4, FGFR3, KIT, NRAS and TP53. Only two B3 thymomas had a mutation in noncoding regions of the SMARCB1 and STK11 gene respectively. Three type A thymomas harbored a nonsynonymous HRAS mutation...

Epidemiological studies based on the "hygiene hypothesis" declare that the level of childhood exposure to environmental microbial products is inversely related to the incidence of allergic diseases in later life. Multiple types of immune cell-mediated immune regulation networks support the hygiene hypothesis. Epithelial cells are the first line of response to microbial products in the environment and bridge the innate and adaptive immune systems; however, their role in the hygiene hypothesis is unknown. To demonstrate the hygiene hypothesis in airway epithelial cells, we examined the effect of lipopolysaccharide (LPS; toll-like receptor 4 ligand) on the expression of the proallergic cytokines thymic stromal lymphopoietin (TSLP) and interleukin 33 (IL33) in H292 cells (pulmonary mucoepidermoid carcinoma cells)...

BACKGROUND: Thymic carcinomas are usually detected in the anterior mediastinum. Thymic carcinoma occurring in the middle mediastinum and showing an image of a cyst is extremely rare. CASE PRESENTATION: A 64-year-old man with a middle mediastinal tumor detected incidentally by a CT scan was referred. Chest CT showed an entirely cystic mass in the middle mediastinum between the bilateral brachiocephalic vein and trachea. We resected the tumor completely in the right recurrent nerve because it had invaded the nerve...

INTRODUCTION: Thymic carcinoma is a rare malignancy often presenting at an advanced stage. Radiation therapy and chemotherapy are often the only treatment options available to physicians. METHODS: A 70-year-old man presented with an unresectable stage III thymic tumor and was treated with 45 Gy in 25 fractions followed by a boost of 21.6 Gy in 12 fractions. He was also treated with bortezomib for multiple myeloma unrelated to his primary malignancy. RESULTS: The patient made a full recovery following the radiation regimen and remained disease free 4 years after the treatment...
