Extrahepatic Biliary Obstruction Caused by Small-Cell Lung Cancer
(Taylor & Francis Ltd, 2001) Kotan, C; Er, M; Özbay, B; Uzun, K; Barut, I; Ozgoren, E
The pancreas is a rare site of metastasis from small-cell lung cancer (SCLC). We present the case of a pancreatic metastasis of small-cell lung, cancer associated with jaundice, in which, initially, the case was evaluated as a primary pancreatic carcinoma and pancreaticoduodenectomy was performed. We also review the reported cases of pancreatic metastases from SCLC.
Primary Composite Tumour With Bipartite Differentiation of the Esophagus
(Acta Medical Belgica, 2000) Ugras, S; Akpolat, N; Er, M; Yalçynkaya, I; Karaayvaz, M
Primary small cell carcinoma of the esophagus is a rare tumour. A primary composite tumour of the esophagus is even rarer and only four cases had been reported in the literature up to August 1998. The definitive histogenesis of this tumour remains controversial in spite of the,additional information provided by electron microscopy and immunohistochemistry. In the presented:case, histologically, the tumour tissue was composed of two malignant components: approximately 50 % of a moderately differentiated squamous cell carcinoma, and approximately 50 % of a small cell carcinoma. A lot of morphological transition zones were observed between the squamous cell carcinoma components and the small cell carcinoma components in some areas in the squamous cell carcinoma component. Histochemically and immunohistochemically, the small cell carcinoma cells demonstrated argyrophil granules, and Cytokeratin and Chromogranin A reactivity, but the squamous cell carcinoma cells demonstrated only Cytokeratin reactivity. Negative reactivity for argentaffin granules, neuron-specific enolase and S-100 were observed in both the small cell carcinoma and the,squamous cell carcinoma components. Histological, histochemical:and immunohistochemical findings suggest that a primary composite tumour of the esophagus may be derived from a totipotent primitive cell in the basal region of the squamous mucosa of the esophagus. The patient received chemotherapy preoperatively but died one month after the initial diagnosis.
Surgical Treatment of Hydatid Cyst of the Lung
(Munksgaard int Publ Ltd, 1999) Yalçinkaya, I; Er, M; Özbay, B; Ugras, S
Hydatid cyst disease is still a problem in Turkey, especially in the east Anatolian region, as well as in many other places in the world. A retrospective review was made of the surgical treatment of 30 patients with pulmonary hydatid cysts during the last 3 yrs. Nineteen patients were male and 11 female with an average age of 23.5 yrs (range 4-44 yrs). Cystotomy and capitonnage mere performed in 28 of the 30 cases (93.4%), The transdiaphragmatic route or simultaneous laparotomy mas preferred when the liver was involved. Albendazole was used in four patients with multiple hydatid cyst due to probable recurrence in the postoperative period. Cough and chest pain were the prominent symptoms in the majority of cases. A single lobe was affected in 22 patients, Unilateral multiple foci were present in four patients and bilateral multiple foci in four. Six patients had concomitant liver cysts. Morbidity was low and no mortality was seen. No recurrences were seen on control chest radiographs during the last 2-yr follow-up. In the treatment of hydatid cyst of the lung, conservative surgical methods such as cystotomy and capitonnage still remain the treatment of choice. Medical treatment could be used for prophylactic purposes and in some instances, but the percutaneous aspiration method should not be performed.
