Large omental metastases of a gastrointestinal stromal tumor.

Gastrointestinal stromal tumors are rare tumors, originating from the interstitial cells of Cajal. They are the most common mesenchymal tumors of the gastrointestinal tract. Metastatic tumor is treated with imatinib mesylate. A case of large metastases of a gastrointestinal stromal tumor to the omentum, diagnosis and treatment principles are presented in this case report.

[Diagnosis of malignant lymphoma of the stomach]. / Skrandzio piktybiniu limofomu diagnozavimas.

There were 2385 (1236 female, 1149 male) cases of malignant lymphoma diagnosed in Kaunas region. Forty-five cases of histologically confirmed malignant gastric lymphoma diagnosed throughout 1981-2000 period are discussed. The disease was diagnosed to 37 patients only after surgery and to other eight by means of endoscopical investigation. Before establishing the correct diagnosis, gastric carcinoma was supposed to 27 patients, gastric ulcer to 12 patients, gastropathia erosiva to 6 patients. Histologically primary non-Hodgkin gastric lymphoma was diagnosed to 29 patients. That consisted 78.3 per cent of all surgically treated patients, 64.4 per cent of histologically confirmed cases and 1.2 per cent of all diagnosed malignant lymphomas. Gastric lymphogranulomatosis was diagnosed to 16 patients. Primary lymphogranulomatosis three cases. After supposed stomach cancer, three patients were operated. All patients were examined by X-ray, CT and endoscopy. Biopsy was taken from pathological or not pathological mucous membrane.

[Percutaneous transthoracic fine needle aspiration of lung tumors by computed tomography examination]. / Uzdara plauciu audinio biopsija, kontroliuojama kompiuteriniu tomografu.

Morbidity of lung cancer in Lithuania is increasing. Early diagnostics of this disease is important, difficult and necessary. During 2001, 169 patients with first and second stages of lung cancer were treated in Department of Thoracic Surgery at Kaunas Oncology Hospital. Age of patients was 30-80 years. We have analysed 20 patients with small peripheral lung tumors. Diagnosis was not confirmed by X-ray and fibrobronchoscopic examination. Percutaneous transthoracic fine needle aspiration of small lung tumors was determined by computed tomography (CT) examination. The diameter of tumors were 2.5-4.5 cm. After percutaneous transthoracic fine needle aspiration the diagnosis of lung cancer was confirmed to 15 (70.5 perc.) patients: carcinoma planocellulare - 13, Adenocarcinoma - 2 patients. Metastasis (solitary) from carcinoma renis to 1, abscessus pulmonis (necrotic masses) to 2, tuberculoma (tuberculosis) to 1 patients. After CT examination, percutaneous transthoracic fine needle aspiration and histologic examination diagnosis were confirmed: Carcinoma pulmonis stage I (T1N0M0-T2N0M0) to 5 patients, Carcinoma pulmonis stage II (T2N1M0-T3N0M0) to 9 patients, Carcinoma pulmonis III (T2N2M0) to 1 patient. There were 3 complications after percutaneous transthoracic needle aspiration: hemorrhage in tumor place to 2 patients, local pneumothorax to 1 patient. In all cases when we can not confirm diagnosis of small peripheral lung tumors we have to do CT examination and percutaneous transthoracic fine needle aspiration.
