CONTEXT Distinction between primary lung carcinomas and metastases from other sites, especially the urinary tract, is a common diagnostic dilemma. As urothelial carcinomas can demonstrate a broad range of morphology and frequently demonstrate squamous differentiation, discerning metastatic urothelial carcinoma to the lung from primary pulmonary squamous cell carcinoma can be challenging. OBJE...
Purpose: Lung adenocarcinoma and lung squamous cell carcinoma (SCC) are the most common non–small cell lung cancer (NSCLC) subtypes. This study was designed to determine whether reduced expression of TGFb type II receptor (TGFbRII) promotes lung adenocarcinoma and SCC
Renal cell carcinoma (RCC) accounts for only 3% of adult malignancies, and the lung is the most common site of metastasis of this tumor, which may be accompanied by pleural metastasis. However, solitary pleural involvement is very rare and its presentation with dyspnea as the first manifestation of RCC is extremely rare.We describe a 39-year-old male with episodes of dyspnea dating back 6...
Three pairs of human tumour cell lines, with one line of each pair resistant to cisplatin, were used to compare the effects of cisplatin and ZD0473 on cellular toxicity and radiosensitization. Whilst all three cell line pairs had one line that was resistant to cisplatin, for ZD0473 the lung tumour HTB56cp and cervical carcinoma ME180 cell lines did not express resistance to their HTB56 and SHA ...
BACKGROUND Sarcomatoid carcinoma is a rare, aggressive, malignant cancer composed of sarcoma and sarcoma-like components, and can occur in different organs such as the thyroid gland, bone, skin, breast, pancreas, liver, urinary tract, and lung. Pulmonary sarcomatoid carcinoma accounts for only a small percentage of lung cancers and has histological variants that include pleomorphic carcinoma, g...
Tumor-to-tumor metastasis is extremely rare in the thyroid glands, and only seven cases of lung carcinoma metastasizing to thyroid tumors have been reported in the literature. We report another two cases of lung carcinoma metastasizing to thyroid neoplasms and review of the literature. The first case was a 64-year-old man presenting with neck mass, hoarseness, and easy choking for 2 months. Ima...
Thymic carcinoma is a rare thymic epithelial tumor in which chemotherapy for advanced disease has not yet been established. Thymidylate synthase (TS) and orotate phosphoribosyltransferase (OPRT) protein expression levels in thymic carcinoma were evaluated as possible indicators of the anticancer activity of 5-fluorouracil (5-FU) drugs using immunohistochemistry (IHC). A total of 24 samples of t...
BACKGROUND This study was designed to determine the accuracy of bronchoalveolar lavage fluid cytology (BAL) using histopathologic examination of transbronchial biopsy specimens as the gold standard in diagnosis of lung carcinoma at our center. MATERIALS AND METHODS A retrospective study was conducted to investigate a total of 388 patients who were suspected of having lung cancer and had under...
