Benign lesions may simulate bronchogenic carcinoma by virtue of radiologic appearance or false-positive cytologic studies. A lung opacity initially suspected to be malignant was, on review, considered to be a loculated effusion. Needle biopsy yielded cells which appeared malignant. The resected lesion was a benign infarct.

Three clones of ectopic hormone-producing cells from a single human neoplasm (bronchogenic carcinoma) show different rates of synthesis and secretion of chorionic gonadotropin and its alpha and beta subunits. For each clone, the amount of one or the other subunit always exceeded that of the complete hormone molecule. These findings may be analogous to unbalanced immunoglobulin chain synthesis i...

Two patients are reported in whom an initial diagnosis of disseminated non small cell bronchogenic carcinoma was subsequently changed into a final diagnosis of extragonadal germ cell tumour. The clinical importance of the differential diagnosis between these two malignancies is highlighted and the management of extragonadal germ cell tumours is discussed.

INTRODUCTION Lung cancer is the leading cause of cancer mortality in most countries. The adrenal glands are common sites of metastatic lung cancer as approximately 40% of subjects with stage 4 bronchogenic carcinoma have adrenal metastases. The prevalence of biochemical hypoadrenalism is, however, remarkably poorly documented. OBJECTIVES Our study aimed to determine the prevalence of primary ...

INTRODUCTION A new classification of bronchogenic carcinoma has been made by the International Association for the Study of Lung Cancer (IASLC) and published by Frank C. Detterbeck et al in the journal Chest (2009). The Thoracic Surgery Department of the Gerona (Spain) University Hospital has re-staged a series of patients with bronchogenic carcinoma who had attempted curative surgery, with the...

Genetic factors are known to play a role in causing lung cancer. Twin cases of bronchioloalveolar, squamous, and anaplastic bronchogenic carcinoma have been previously reported. We describe mirror-image twins with adenocarcinoma of the lung occurring in mirror-image locations. They shared smoking and an occupational risk, carpentry, in addition to identical genetic backgrounds.
