ABSTRACT

Background: Chest wall tumors are rare and mostly malignant. More than half of the malignancies are primary and the remainder are metastatic. Many studies have reported that metastatic lesions occur with about the same frequency as primary tumor. We evaluate common histological types of chest wall tumors in a tertiary center for respiratory and thoracic diseases (National Research Institute of Tuberculosis and Lung Disease). Method: We performed a retrospective study of chest wall tumors at National Research Institute of Tuberculosis and Lung Disease (NRITLD) from April 2001 to March 2010. The pathology slides of patients were retrieved from the pathology archive of NRITLD and reviewed by two pathologists. The lesions were classified as primary or metastatic according to the relevant clinical data and imaging findings. Result: A total of 124 chest wall tumors were identified in patients with a mean age of 47.7 years (range 4-90 years). The male/female ratio was 2:1. The most commonly affected side was the right (42.7%). There were 105 malignant tumors (84.7%), out of which 49 (46.2%) were primary and 57 (53.8%) were metastatic in origin. The majority of the metastatic lesions were epithelial tumors (36/57) (63.1%). The metastatic origin was clear in 51 cases, mostly arising from the lungs (35.7%). The most common types of primary chest wall tumors were primitive neuroectodermal tumor (15/49, 30.6%), chondrosarcoma (7/49, 14.3%), and malignant fibrous histiocytoma, undifferentiated pleomorphic sarcoma (5/49, 10.2%). The most common benign tumor was lipoma (5/18, 35.7%). Conclusion: Most common tumors of chest wall in this study were malignant, mostly metastatic epithelial neoplasms.
