  • A solitary fibrous tumor in the pleura has been reported occasionally, but extremely rare in themediastinum. The histogenesis of this tumor has been still in controverse, but recent studies paid attention to it a mesenchymal origin by the immunohistochemical and ultrastructural bases. A few cases, reported in the literature, suggest that the mediastinal solitary fibrous tumor occurs more commonly in adult and shows slightly higher incidence in women. Its aggressive behavior such as recurrence rate and distant metastasis, is more prominant than reported in solitary fibrous tumor of the pleura. No single histologic feature allows an assumption definite prognosis. Surgical resection of this tumor is usually curative although the recurrence or distant metastasis are reported in about half of the patients. This report is a case of solitary fibrous tumor in the mediastinum in a 16-year-old female patient.She underwent surgical resection and her postoperative result was satisfactory.

  • A primary metastatic malignant plasma cell tumor was presented in a 7-year-old, female, mixed breed dog. The dog was admitted to Veterinary Teaching Hospital at College of Veterinary Medicine, Seoul National University after suffering from depression, anorexia, and dyspnea. The dog was euthanized due to poor prognosis. At necropsy, numerous, firm and tan round nodules, 1 to 2 cm in diameter were noted in the ribs. The nodules formed chain or were occasionally coalescing, causing osteolysis of the ribs. A large amount of clear fluid was present in the thoracic cavity. The spleen and liver were markedly enlarged and congested. Histologically, the nodular masses were diagnosed as plasma cell tumor which was believed to be originated from the rib. Evidence of metastasis was observed in the spleen, liver, and kidney.

  • Cutaneous squamous cell carcinoma has a high incidence. However, regional metastasis occurs infrequently because skin cancer is usually recognized and treated early. We report the case of squamous cell carcinoma around the earlobe in a 74-year-old male patient. The cutaneous squamous cell carcinoma invaded ipsilateral parotid gland directly without lymphatic spreading. Wide excision was made with 1.5 cm margin and immediate reconstruction was performed with radial forearm fasciocutaneous free flap. During operation facial nerve was preserved. No recurrence was noted for 5 years and the patient was satisfied with good aesthetic result. Cutaneous squamous cell carcinoma spreads to the parotid gland usually through lymph nodes and there are few reports of invasive organ damage by direct invasion. We experienced a case of direct invasion to parotid gland without lymph node involvement of cutaneous squamous cell carcinoma and treated the cancer adequately with wide excision and free flap coverage.

  • Treatment of metastatic carcinoma of the oral cavity can be a challenge due to its rarity. The current case report details metastatic carcinoma of the mandible originating from follicular thyroid carcinoma, which is the second most prevalent tumor of the thyroid. As the mandibular lesion developed, the primary thyroid lesion of thyroid. Here, we report a case of metastatic carcinoma of the mandible in a 67-year-old female that was treated with partial mandibulectomy and fibular free flap.

  • A 12-year-old neutered male Golden Retriever presented with a progressively enlarging mass in the submandibular region. Histopathological diagnosis confirmed lymphangiosarcoma with metastasis to the liver and spleen. The pleomorphic neoplastic endothelial cells of the tumor grow directly on bundles of dermal collagen, forming numerous clefts and interconnecting channels that are devoid of conspicuous hematic elements. As lymphangiosarcoma is an uncommon malignant neoplasm, the number of previously reported cases and information of the tumor is limited. The present report describes the clinical history and histopathological diagnosis of a progressive lymphangiosarcoma in the submandibular region with metastases in a dog.

  • Colorectal peritoneal metastasis has been an incurable disease for centuries. However, since the new millennium, recent advancements in therapies are achieved with modern chemotherapeutic agents, target agents, and immune checkpoint blockade introduction. Modern chemotherapies, from a nearly nonexistent median survival if untreated, have raised the duration to 16 months with target agents. Experts have once again surpassed its limit by introducing intraperitoneal chemotherapy and cytoreductive surgery (CRS). Numerous clinical trials regarding CRS and hyperthermic intraperitoneal chemotherapy have now opened new doors in peritoneal carcinomatosis treatment, even securing complete remission. In addition, up-to-date modalities, such as pressurized intraperitoneal aerosol chemotherapy and immunotherapies, showed promising results at an early stage.

  • Solid pseudopapillary tumor (SPT) of the pancreas is a rare neoplasm with low malignant potential, which has a good prognosis with more than 95% survival at 5 years. Only approximately 10% to 15% cases of SPTs are malignant. This report presents a case of a 38-year-old woman who developed malignant SPT of the pancreas with synchronous multiple hepatic metastases. She underwent a successfully complete surgical resection for multiple hepatic metastatic tumors in addition to primary tumor.

  • The pulmonary sarcomatoid carcinoma is a rare malignant tumor, which is composed of an admixture of carcinomatous and sarcomatous components, and accounts for 0.3% of all pulmonary neoplasms. Clinicopathological features are often related to anatomical location: central endobronchial type and peripheral parenchymal type. Noninvasive diagnostic test had a low yield in detection sarcomatoid carcinoma. Metastasis to the regional lymph nodes and to distant organ is common. The prognosis is poor and the median survival is about 15 months. We report two cases of pulmonary sarcomatoid carcinoma with review of literatures.

  • Small cell carcinoma is a highly malignant esophageal tumor composed of anaplastic small cells with features very similar to those of its pulmonary counterpart. The prognosis is poorer than that of squamous carcinoma of the esophagus because of its propensity of generalized spread and metastasis. Once the diagnosis of small cell carcinoma was established, surgery should be undertaken as early as possible. We have described an experience of small cell carcinoma of the lower esophagus in a 72 year old male patient with a review of the literatures regarding treatment methods and prognosis.
