Abstract
A 52-year-old female showed a coin lesion in the right lower lobe on her chest X-ray film. She had no complaints.
A right lower lobectomy revealed an elastic hard, yellow tumor in the right posterior basal segment, measuring 3×3×2.5cm. Histologically, the main part of the tumor was composed of spindle-ahaped fibroblast-like cells with a typical storiform pattern, and of round histiocyte-like cells. There were no bizarre hyperchromatic nuclei and abnormal mitoses.
These findings confirmed this tumor was compatible with benign fibrous histiocytoma.
Although benign fibrous histiocytoma is rare, it should be included in diseases for the differential diagnosis of lung mass lesions. At present, 16 months after the operation, the patient is in good health without evidence of recurrence.
