Figure 2 (A) Low magnification of the bronchial wall demonstrates a well-defined border and highly cellular submucosal mass (H&E, 100×). (B) High magnification of the bronchial mass demonstrates fascicular arrangement of relatively well-differentiated epithelioid-to-spindle-shaped cells, moderately increased cellularity, and lack of nuclear pleomorphism, with brightly eosinophilic cytoplasm (inset: hemangiopericytoma-like blood vessel), H&E 400×.
