Inflammatory myofibroblastic tumor (plasma cell granuloma) of the lung

Gross photograph showing a large inflammatory myofibroblastic tumor (plasma cell granuloma) resected from a 21 year old man. Plasma cell granulomas are typically smaller but have been reported up to 36 centimeters in greatest dimension. The gross appearance is typically that of a firm, well-circumscribed solitary pulmonary nodule with a homogeneous solid cut surface. Areas of calcification can occur, as in this example.
