  • An 8-year-old, female lionhead rabbit with clinical sign of hematuria and vaginal discharge with/without blood was submitted to a local animal hospital. On exploratory laparotomy, three round to oval masses were observed in both uterine horns. The lumen of uterus was severely obstructed and distorted because of massive neoplastic proliferation. Histopathologically, the uterine masses revealed papillary projections along with irregular glandular structures into the lumen. The neoplastic foci were composed of numerous irregular sized neoplastic glands originated from uterine glands. These neoplastic cells showed very strong invasive tendency to muscle layer, therefore emboli of neoplastic cells were located in lymphatics. According to immunohistochemistry, the tumor cells in uterine masses demonstrated strong positive signals for cytokeratin, but negative for vimentin. Based on the gross, histopathologic and immunohistochemical features, this case was diagnosed as uterine adenocarcinoma in lionhead rabbit.

  • Mediastinoscopy is a surgical endoscopic technique used mainly for examination and biopsy of lesions of the superior and posterior middle mediastinum. It is particularly concerned with diseases that primarily or secondary involve the paratracheal and parabronchial lymphatics. A total of 18 cases of mediastinoscopy are presented with a detailed analysis of indications and results. Of these mediastinoscopy was positive in i0 [56%] and negative in 8 [44%]. The 10 positive mediastinoscopies were diagnostic in 4 patients with malignant lymphoma, 5 patients with carcinoma of the lung, one patient with active pulmonary tuberculosis. Of 8 negative mediastinoscopies, one was inoperable due to recurrent laryngeal nerve involvement, 7 patients were subjected to radical resection. Complications of mediastinoscopy were developed in 2 cases, one was minimal degree of subcutaneous emphysema on anterior chest wall, and the other was widening of right mediastinal border due to hematoma. Two complications were completely absorbed after 7 days.

  • Lymph node status is the single most important prognostic factor in oral cancer because lymph node involvement decreases overall survival by 50%. Appropriate management of the regional lymphatics, therefore, plays a central role in the treatment of the oral cancer patients. The purposes of this article are to present the history of neck dissections, including current neck dissection classification, describe the technique of the most common neck dissection applicable to oral cavity cancers, and discuss some of the complications associated with neck dissection. Finally, a brief review of elective neck dissection and sentinel lymph node biopsy will be presented. It is necessary that dentists have to be interested in oral cancer and these interest will make it possible to prevent oral cancer, detect it earlier and also improve the prognosis, survival and the quality of life of survivors.

  • Carcinoma of the breast has been treated by surgery followed by irradiation of the chest wall and regional lymphatics treatment planning of the breast cancer is required that lung must be spared as much as possible. However megavoltage irradiation of the internal mammary chain results in high dose to underlying heart, esophagus and spinal cord. Electron beam can be used for the irradiation of the internal mammary chain instead of megavoltage beam. We studied dose distribution of single anterior electron field, compared with traditional treatment methods. 12 and 15MeV electron beam with bolus has good dose distribution to spare underlying lung tissue and other organs.

  • Mediastinum is the space located between the right & left lung lobes in the center of the thorax, and contains many vital organs such as heart, aorta, trachea, esophagus, vagus nerve, lymphatics. So the infection of mediastinal space causes a serious and potentially fatal process. Like other infections, surgical drainage, aggressive antibiotic therapy and supportive care are recommended for optimal outcome. Airway management in the presence of the neck, glottic edema, elevation of the tongue is a formidible problem especially in the case from odontogenic origin. We have recently encountered such a case resulting in a number of local and systemic complications.

  • A ten-year-old dog was presented with pancreatitis and increased hepatic enzymes. On necropsy a large firm mass was observed in the liver extending to the gall bladder. Smaller masses with similar texture were found in multiple organs including lung, stomach, pancreas, lymph nodes, omentum, and mesentery. Neoplastic cells were spindle shaped with prominent osteoid production and occasional trabeculae of woven bone. Tumor cell emboli were observed in the blood vessels and lymphatics of the omentum and stomach. Hepatic osteosarcoma with systemic metastasis is very rare and may serve to broaden the diagnostic spectrum of hepatic and pancreatic diseases in dogs.

  • Tertiary lymphoid structures (TLS) are ectopic lymphoid tissues involved in chronic inflammation, autoimmune diseases, transplant rejection and cancer. They exhibit almost all the characteristics of secondary lymphoid organs (SLO), which are associated with adaptive immune responses; as such, they contain organized B-cell follicles with germinal centers, distinct areas containing T cells and dendritic cells, high endothelial venules, and lymphatics. In this review, we briefly describe the formation of SLO, and describe the cellular subsets and molecular cues involved in the formation and maintenance of TLS. Finally, we discuss the associations of TLS with human diseases, especially autoimmune diseases, and the potential for therapeutic targeting.

  • Background: The lung is the most common site of metastasis and usually it manifests as a single or multiple nodules in chest X-ray. But less commonly the cancer spreads through the lymphatics and X-ray shows diffuse reticulonodular densities. Sometimes, patient is presented with respiratory symptoms only with interstitial lung infiltration before the signs of primary tumor and in that cases, the differential diagnosis with other interstitial lung disease is required. We have experienced 5 such cases, who were diagnosed as lymphangitic carcinomatosis by transbronchial lung biopsy. Methods: Clinical manifestation, pulmonary function test, modified thin section CT, bronchoalveolar lavage and transbronchial lung biopsy were done. Results: The primary tumor was gastric cancer in 3, lung cancer in 2. Pulmonary function test showed restrictive pattern with low DLco in 2 patients and obstructive pattern in one. Bronchoalveolar lavage showed lymphocytosis in 4 patients and malignant cells were found in one patient. Transbronchial lung biopsy revealed malignant cells localized to the lymphatics (peribronchial, perivascular and perialveolar). Cell type was adenocarcinoma in 4 and squamous cell carcinoma in one. Conclusion: Rarely lymphangitic carcinomatosis can be presented as diffuse interstitial lung disease and easily diagnosed by transbronchial lung biopsy.

  • Lymphangioleiomyomatosis (LAM) is a rare disease in women in childbearing age leading to progressive respiratory failure. LAM is characterized by an abnormal harmartomatous proliferation of smooth muscle cells surrounding the blood vessels, lymphatics and airways in the lung. This proliferation leads to airway obstruction, cystic alveolar change and lymphatic obstruction. Patients present with dyspnea, pneumothorax, cough, chest pain, hemoptysis, and chylous effusion. Although lung transplantation is the only therapeutic modality in end-stage LAM with respiratory failure, there has not been any report of successful treatment in Korea. We report one case of successful left single lung transplantation in a 40 year old woman suffering from end-stage LAM.
