RODRIGUEZ, Cynthia et al. Clinical and pathological characteristics of tumors of the mediastinum in a university hospital. Rev. Cir. Parag. [online]. 2013, vol.37, n.2, pp.22-25. ISSN 2307-0420.

SUMMARY Mediastinal neoplasms are rare tumors that can occur at any age but are most common between the third and fifth decade of life. Approximately 40% of the masses are asymptomatic and are discovered incidentally on a routine chest radiograph. The aim of this work is to determine the frequency and characteristics of this type of tumors in a general university hospital. Patients and Methods: An observational, retrospective, cross- sectional descriptive. We included all patients diagnosed with primary mediastinal tumor with pathologic confirmation, during the period 2008-2012. Results: Of the 795 adult patients registered with the Department of Oncology, 27 (3.4%) had mediastinal tumor pathologies. 19 (70%) were male and the average age was 41 years. The most common topographic location corresponds to 63% (17 cases) the anterior mediastinum. The most common histological types were: the germinal source with 6 cases (22%) and lymphomas (Hodgkin and non-Hodgkin) occurred in 4 cases each (24% total). Conclusions: The frequency of mediastinal tumors was 3.4%. They mostly appear in male patients (70%), and the average age of onset is 41 years. The most common topographic location is the anterior mediastinum (63%). The most common histological type are lymphomas and germ cell tumor origin.
