OBJECTIVE To report a case of an extraskeletal myxoid chondrosarcoma (EMC) arising from the jugular foramen. EMCs are tumors usually seen in the deep soft tissues of the extremities and are rarely seen within the intracranial cavity. The histological differential diagnosis includes chordoma, conventional chondrosarcoma and chordoid meningioma, among others.(More)
Thymic carcinoma frequently spreads to the pleural space, regional lymph nodes, liver and lungs. However, an initial clinical presentation involving spinal or multiple bone metastases in patients with thymic carcinoma is extremely rare. We experienced two cases of thymic carcinoma that initially presented with spinal compression and severe pain due to(More)
Most mantle cell lymphoma patients show remarkable disseminated disease at the initial diagnosis. We describe two cases of mantle cell lymphoma mainly involving thoracic lesions at the initial presentation of the disease. The clinical presentations were right hilar lymphadenopathy in one case and right pleural thickness in the other. The diagnosis of mantle(More)
BACKGROUND Carcinoma showing thymus-like differentiation (CASTLE) is an extremely rare malignant neoplasm of the thyroid that originates from ectopic thymic tissue. No sufficient evidence exists regarding the efficacy of chemotherapy for cases with distant metastases or advanced disease because of the rarity of the disease itself. PATIENT We report a case(More)
We herein encountered a case of abdominal wall dermatofibrosarcoma protuberans (DFSP) that developed pulmonary and pancreatic metastases 5 years after complete resection. Because specific rearrangements of the platelet-derived growth factor beta (PDGFB) locus by a novel fluorescence in situ hybridization method was detected, the patient was treated with(More)
Alectinib, a novel alternative anaplastic lymphoma kinase (ALK) inhibitor, is highly effective against ALK-positive non-small cell lung cancer (NSCLC) and is well tolerated. Molecular targeted agents generally have little contribution to alopecia. We encountered a case of alopecia that developed gradually over 2 months after initiation of alectinib(More)
Anthracycline-based regimens with cisplatin have been commonly used for inoperable and relapsed thymoma. However, little information is available regarding the usefulness of salvage chemotherapy. Here, we describe a case of invasive thymoma associated with myasthenia gravis that showed a marked response to third-line chemotherapy, with single-agent(More)
The present study was performed to evaluate the clinical characteristics and survival outcomes in patients with small cell lung cancer (SCLC) detected by low-dose computed tomography (CT). We retrospectively reviewed clinical records of patients with SCLC treated at our hospital between 1997 and 2011 and selected patients with SCLC detected by CT screening.(More)
