BACKGROUND Primary lung cancer is extremely rare in children, while secondary malignancies reportedly develop in 2% to 3% of pediatric osteosarcoma survivors. CASE PRESENTATION A 14-year-old girl was found to have two pulmonary lesions on computed tomography. These tumors had developed 1 year after osteosarcoma surgery. Segmentectomy of right segment 1 and wedge resection of right segment 9 w...

Detectable levels (>0.2 pinol/ID" cells) of one or more prostanoid species resultant to calcium ionophore A23187-induced biosynthesis from endogenous arachidonic acid were distributed in 28 cell lines derived from different histolÃ3gica!classes of lung tumors as follows: large cell undifferentiated carcinoma (3 of 3 cell lines); adenosquamous carcinoma (1 of 2 cell lines); squamous cell carcino...

Association between progressive systemic sclerosis (PSS) and lung malignancy is rare yet well recognised. In order of frequency bronchioloalveolar carcinoma (BAC) is most common followed by squamous cell carcinoma, oat cell carcinoma, anaplastic carcinoma of lung. We present a 55 year old non-smoker male patient with PSS, who presented to us with progressively increasing shortness of breath and...

In lung transplantation, the presence of bronchogenic carcinoma in the native organ is uncommon, but doubtless affects patient survival, independently of the transplantation process itself. We describe 2 cases in which a primary tumor was found in the explanted lung--1 case of adenocarcinoma in a patient with pulmonary emphysema and 1 case of bronchioloalveolar carcinoma in a patient with idiop...

Most squamous cell carcinoma of the lung arises in the large bronchi and causes bronchial obstruction. We report a 74-year-old man with a squamous cell carcinoma of the lung whose roentgenogram revealed a lobar consolidation without collapse. A postmortem examination showed that the tumor cells filled the alveolar spaces completely without destroying the original architecture of the lung. The f...
