%0 Journal Article %T Rare thoracic mass lesion - Myofibrobastoma %A Sahni Vaibhav %A Sunandan Sikdar %A Agarwal Satish %A Singh Narinder %J Indian Journal of Cancer %D 2005 %I Medknow Publications %X Mesenchymal soft tissue masses are uncommon tumours of the chest. Myofibroblastoma is a recently described entity consisting of cells with origin from the myoepethelial cell, mostly seen as benign well-circumscribed neoplasms of the breast tissue. Though usually classified as a benign lesion, rarely it can be multifocal and prone to recurrence. We describe below the case of a 26-year-old female who presented with exertional dyspnoea and evidence of a massive mass lesion in the left hemithorax causing mediastinal displacement to the opposite side. On histological and immunophenotypic analysis, a diagnosis of the very rare thoracic myofibroblastoma was made. The incidence, salient features, pathological differential diagnoses and treatment are reviewed. %K Mesenchymal tumours %K Myofibroblastoma %K Pulmonary myofibroblastic tumour %U http://www.indianjcancer.com/article.asp?issn=0019-509X;year=2005;volume=42;issue=3;spage=161;epage=164;aulast=Sahni
