Objectives: Clubbing is the enlargement of the distal segment of a digit due to an increase in soft tissue. It can be hereditary or acquired. Acquired clubbing is seen in a wide variety of diseases including chronic inflammatory diseases, infections and congenital heart diseases. It can also be a paraneoplastic marker. It has been proposed that ectopic growth hormone is secreted in case of lung...

A panel of seven monoclonal antiepithelial antibodies of different specificities, including anticytokeratin, human milk fat globule membrane, Ca, and carcinoembryonic antigen (CEA) were used with the alkaline phosphatase-antialkaline phosphatase (APAAP) immunostaining technique to determine their value in the differentiation between benign and malignant mesothelial cells and lung carcinoma in h...

Lung carcinoma is subdivided into small cell carcinoma and non-small cell carcinoma (NSCLC). NSCLC is heterogeneous group of carcinomas and accounts for 70-80% of lung cancer. NSCLC is further divided into adenocarcinoma, squamous cell carcinoma, and large cell carcinoma. Activating somatic mutations of the tyrosine kinase domain of epidermal growth factor receptor (EGFR) have recently been cha...

Invasion into the lumen of the main pulmonary artery is an uncommon mode of extension in lung carcinoma and its prognostic significance remains unclear. We describe here two resected cases of lung carcinoma that showed such a rare tumor spread. Although a preoperative evaluation, such as angiography or perfusion scan of the lung, had shown a significant decrease in circulation, we could not dia...

Introduction: Metastatic lesions of the oral cavity are extremely rare, accounting for approximately 1% of all malignant oral tumors. The most common primary sources of metastatic tumors in the oral region are, from the most to the least common, the breast, lung, kidney, bone, and colon. Renal cell carcinoma accounts for nearly 3% of all adult malignancies. It usually metastasizes to the lungs,...

We tested whether Ca(2+)-mobilizing neuropeptides can function as growth factors for small cell lung carcinoma cells. The neuropeptides bradykinin, neurotensin, cholecystokinin, and vasopressin at nanomolar concentrations stimulated a rapid and transient increase in the intracellular concentration of Ca2+. Crucially, these peptides in the same concentration range also caused a marked increase i...

We report on three Caucasian Greeks 2 males and 1 female (67, 54 and 62 years old) that were operated with sarcomatoid carcinoma of the lung, an uncommon tumor that sometimes is referred as pleomorphic carcinoma (spindle and giant cell carcinomas). These tumors are encountered in the thorax far more often than true sarcomas. There are many erroneous reports of pulmonary sarcomas made before the...

Pilomatrix carcinoma is a rare locally aggressive hair-follicle tumor. We report a 54-year-old man who presented with a tumor in the left flank that was found by skin biopsy to be pilomatrix carcinoma. A contrast-enhanced computed tomographic scan of the chest, abdomen, and pelvis showed multiple small nodules in both lungs and lymphadenopathy in the abdomen. Video-assisted thoracoscopic biopsy...
