Clinical and epidemiological characteristics of lung cancer cases in Qatar

This study documents for the first time the clinical and epidemiological characteristics of lung cancer cases in Qatar from 1998 to 2005. The age-standardized incidence rate was higher than that in many other Gulf countries: 8.95 per 100 000 [15.2 per 100 000 for males; 3.95 per 100 000 for females]. Mean age at diagnosis was 57.5 years. Most patients were current smokers or ex-smokers at the time of diagnosis [82.5%]. Unlike other Gulf countries, adenocarcinoma was the predominant type in both Qatari nationals and expatriates [43.9% of lung cancer types]. Many cases were in an advanced stage at diagnosis [64.2% at stage IV]. Incomplete information was available on mortality rate due to the migration of expatriates

Solitary arteriovenous hemangioma of the lung without fistula: report of a case and literature review

Arterio-venous hemangiomas [also called vascular malformations] are uncommon lesions in general and very rarely reported as solitary lung tumors with no evidence of fistula formation or clinical evidence of shunting. We report the case of a 49 year old Indian male who presented to our institution with a right hilar lung mass which was histologically proven to be a classical arterio-venous hemangioma [vascular malformation]. The patient did not have clinical or radiological evidence of fistula or shunts formation
