Despite the fact, that lung cancer is more common among older smoking men, however it may also develop among young women without a smoking anamnesis. We report here a history of a non-smoking woman, 40 years old, with a diagnosis of lung adenocarcinoma at IV stage. Despite the fact, the woman received three lines of palliative chemotherapy, the disease progressed. After the sample of the tumor was tested by genetic approach, ROS1 mutation was detected, and the patient was treated with a ROS1 inhibitor, Crizotinib. Sharp improvement was observed already after the first week of treatment. After one-month adenocarcinoma shrink, and specific supraclavicular lymph nodes disappeared. Unfortunately, due to problems with financing the treatment was stopped, after what the disease began to progress rapidly, and the patient died after a month due to brain metastasis. This case is noteworthy also because the patient was first diagnosed a thrombophilia with thrombi present in deep calf veins, left heart ventricle and lungs Adenocarcinoma was discovered occasionally when during video-assisted thoracoscopic surgery biopsy specimen was taken from suspicious mass in the lower lobe of the right lung. This story reminds us that lung carcinoma may start with a paraneoplastic syndrome, like thrombophilia as in this case and finding of adenocarcinoma of the lung in young, non-smoking persons is indicative for possible ROS1 gene mutation. In such cases early treatment with ROS1 protein-tyrosine kinase inhibitors should be started as soon as possible.

Clinical, histopathological and surgical evaluations of persistent oropharyngeal membrane case in a calf

A male, 4 days old and 20 kg Simmental calf was evaluated for regurgitation and hyper salivation since birth. The mother became pregnant by artificial insemination and the pregnancy was the second of the mother. A membrane closed the pharynx and a diverticulum on dorsal of this membrane was seen during oropharyngeal examination through inspection. Membrane was also viewed by endoscopy under general anaesthesia. Larynx and oesophagus were imaged by bronchoscopy through the back side of the membrane. After these applications, it was decided that soft palate adhered firmly to the root of tongue causing congenital atresia. Surgical treatment of oropharyngeal membrane was carried out under general anaesthesia. Firstly, tracheotomy was performed for to ease breathing and membrane removed by electrocautery application. Intensive fluid accumulation and oedema formation at the incision area were detected by endoscopic examination following operation and the calf had severe dyspnoea two days after operation and died due to respiratory insufficiency. At necropsy, severe inflammatory reaction, laryngeal oedema and intensive salivation at the surgical side was determined. Direct imaging techniques should be used to determine in the closed oropharyngeal lumen. Moreover, nasopharyngoscopy should be considered to image larynx and oesophageal way. Present case is the first report with concern to pharyngeal membrane formation together with direct imaging and surgical procedures. Therefore, it was considered that this case report could be useful for colleagues and literatures.
