Rheumatoid arthritis (RA) is a chronic, autoimmune disease of unknown etiology, characterized by symmetrical polyarthritis resulting in damage to cartilage and bone. It is estimated to have a worldwide prevalence of 1%, with a 2to 3-fold excess in females and a peak in prevalence between the ages of 45 and 54 years (1). Several studies have described an increased risk of malignancy in subjects ...

Bronchial carcinoid tumors account for 1–2% of all primary lung tumors and are separated into 2 subgroups: typical and atypical carcinoids. Atypical carcinoids as intermediategrade malignancies can metastasize more frequently, thus exhibiting poorer prognosis than the low-grade typical carcinoid tumors. Surgical resection remains the mainstay of treatment for pulmonary carcinoids. Bronchoscopic...

BACKGROUND Carcinoid tumors are slow growing neuroendocrine tumors which can originate from various sites within the body. A carcinoid tumor originating in the medulla spinalis has not previously been reported in the literature. CASE REPORT We report a case of a 33-year-old man, presenting with a five-month history of bilateral lower extremity pain, as well as paresthesia, and mild weakness i...

Analyses of enzymes from various metabolic pathways in pulmonary carcinoid tumors and radiological measurements of their volume increase were compared with those for lung carcinomas of various cell types. The results describe new biochemical features in carcinoid tumors, present the first quantitative evidence for their slow growth rate (i.e., long doubling time) in vivo, and show that measurem...

BACKGROUND Colorectal carcinoid tumors are often described as being low-grade malignant. The objective of the current study was to address the clinicopathological features and outcomes of patients with colorectal carcinoid tumors. METHODS A total of 63 patients with colorectal carcinoid tumors were identified and evaluated using surgical pathology files and medical records between January 200...
