Inflammatory myofibroblastic tumor of lung in an adult female-a rare case.

Inflammatory myofibroblastic tumor occurs primarily in the viscera and soft tissue of children and young adults. This tumor is potentially malignant because of its tendency for local recurrence and its ability to metastasize. It is composed of a variable mixture of collagen, inflammatory cells, and usually bland spindle cells showing myofibroblastic differentiation.
