Primary pericardial mesothelioma is extremely rare and the incidence is low among the mesotheliomas that originate from other parts of the body. The prognosis of the tumor is unfavorable due to its late presentation, difficulties in early diagnosis and complete resection, and the limited treatment options. Herein, we report a case of pericardial mesothelioma. The patient is a 55-year-old woman who presented with chronic cough and dyspnea. During the examination, pericardial effusion was found and pericardial window formation was followed. She visited our hospital because of persistent dyspnea, with right shoulder and chest pain. Four discrete masses were discovered in the chest CT. CT guided-fine needle aspiration biopsy was negative for malignancy. Right exploratory thoracotomy and partial resection of 3${\times}$3 cm mass abutting pericardium was performed and was histologically diagnosed as malignant mesothelioma, biphasic type. Pericardial mesothelioma is rare, but it should be remembered as an important differential diagnosis in patients with persistent pericardial effusion and symptoms of dyspnea and constrictive pericarditis.

We experienced a case of primary sternal tuberculosis with destroyed midsternum and bony defect. An 22-year-old female was admitted to our hospital two times for severe sternal pain and spontaneous fracture without history of trauma. On hospital admission, chest X-ray and chest CT showed destruction of midsternum and soft tissue swelling. Fine needle aspiration cytology revealed tuberculous osteomyelitis with cold abscess. And the patient was treated with usual anti-tubeculosis medication for preoperative preparation. At operation, we confirmed midsternal destruction with cold abscess and multiple sinus tracts. After removal of diseased sternal segment and cold abscess, we performed sternal reconstruction with autologus iliac bone graft. The pathologic report was compatible with tuberculous osteomyelitis and caseous necrosis The postoperative course was smooth and uneventful, and she remains well without sternal instability two months later.

Epithelioid hemangioendothelioma (EHE) is a relatively rare and moderately aggressive type of vascular tumor. We describe a case of EHE that presented in a 24-year-old woman as a palpable nodule in the left cervical area. Radiological examinations and fine-needle aspiration cytology led to a preliminary diagnosis of metastatic lymphadenopathy with an unknown primary site. However, during surgery, we determined that the nodule was an intra-vascular tumor arising from the left internal jugular vein. The histopathological examination revealed cords of epithelioid endothelial cells distributed in a hyaline stroma, compatible with a diagnosis of EHE.

Extramedullary hematopoiesis is a common compensatory mechanism of chronic anemia, but an asymptomatic posterior mediastinal mass is rarely diagnosed as an extramedullary hematopoiesis after surgical resection. The differential from neurogenic tumors is important, but fine needle aspiration biopsy is not recommended because of the difficulty of approach and risk of bleeding. Although diagnosis and treatment can involve resection via thoracotomy, video-assisted thoracic surgery may also be a useful strategy. We performed video-assisted thoracic surgery on a 59-year-old man for posterior mediastinal extramedullary hematopoiesis, with no evidence of recurrence or related hematologic diseases.

A 12-year-old, female, Maltese dog was presented with otic signs, such as pruritus and malordorous discharge. Medical treatment of otitis externa had been carried out for several months at primary animal hospital. Radiography, ultrasonography (US), computed tomography (CT), fine needle aspiration (FNA), and histopathological examination were performed for the diagnosis of ceruminous gland adenocarcinoma. Total ear canal ablation and lateral bulla osteotomy were performed for excision of the tumor. Facial nerve paralysis developed after surgery is getting better through the acupuncture therapy.

A 12-years-old Maltese (castrated male) dog with jaundice and purulent discharge from the shoulder was referred to the Veterinary Medical Teaching Hospital of Chungnam National University. A physical and laboratory examination revealed that the mucosa of the conjunctiva and the sclera were icteric, and the liver functional enzyme level and the total bilirubin level were increased. Duodenal caudal deviation caused by suspected masses in diameter of about 2 cm was shown by radiographic and ultrasonographic examinations. Using fine needle aspiration (FNA) and computed tomography (CT), the dog was diagnosed with alimentary lymphoma. The dog was treated with chemotherapy. Hematuria was discovered and dysuria occurred because of sterile hemorrhagic cystitis, which is a unique complication resulting from the use of cyclophosphamide.

Insular carcinoma(poorly differentiated thyroid cancer) is defined as a aggressive, follicular-derived thyroid carcinoma with behavior intermediate between follicular/papillary and anaplastic carcinomas. It was described by Carcangiu in 1984, but its prognosis, classification and the origin is not yet clear. And preoperative fine needle aspiration cytology of insular carcinoma has not been satisfactory. We experienced a case of advanced thyroid insular carcinoma with invasion of the sternum. So we intend to present the case with a review of the related literatures.

We experienced a case of the papillary thyroid carcinoma seen as a huge solid lateral neck mass. The mass grew very slowly over the period of 30years up to 10cm in diameter while relatively well sparing the surrounding tissues. Physical examinations, CT scan, and fine needle aspiration cytology did not reveal any strong suggestions for evidence of malignancy. But it was pathologically diagnosed as metastatic thyroid carcinoma by excisional biopsy. We emphasize that for a large solitary neck mass which persists for several decades, head and neck surgeons should always keep in mind the possibility of metastasis from the malignancy of thyroid gland.

Sinonasal malignant tumors comprise less than 1% of all cancers and 3% of all malignant tumors of the head and neck, which explains a lack of large series addressing the clinical characteristics and management of these tumors. Neck node metastasis occurs in only about 7% to 15% of malignant tumors compared with other head and neck cancers. A 90-yr-old woman presented with left palpable neck mass and right nasal mass occupying nasal cavity. Fine needle aspiration biopsy of left neck mass results in metastatic squamous cell carcinoma(SCC). PET/CT shows intense FDG uptake in right nasal cavity with bone invasion. Histopathologic examination of excised lesion in the right nasal cavity revealed SCC. We report here on a primary sinonasal SCC with contralateral lymph node metastasis.

A 62-year-old female patient had goiter for twenty years. She visited out-patient clinic with a hoarse voice and intermittent breathing difficulties. About protruding 15cm sized mass located the anterior neck and right vocal cord paralysis was observed. Preoperative CT scan was strongly suspected of thyroid gland cancer and cervical lymph node metastasis. Therefore, fine needle aspiration test was performed and surgical treatment was planned with the histopathologic results (papillary thyroid carcinoma). Surgery was performed with total thyroidectomy, bilateral cervical lymph node dissection, and right selective nodal lymph node dissection (level II-V). During operation right thyroid seemed to be adherent to surrounding tissue and the blood vessels were extremely engorged. There was hypotensive crisis because of intraoperative excessive bleeding. However it was managed by repetitive transfusion. The operation was completed without abnormalities. She underwent 4 times of bleeding control operation due to postoperative bleeding. After complications were improved, we are currently undergoing out-patient follow up without morbidity.
