ABSTRACT
A-73-year-old woman was referred to our hospital because of a chest X-ray abnormality found on a routine medical checkup. She had no respiratory symptoms. Laboratory investigations were unremarkable. A chest CT demonstrated a round mass in the lingular bronchus. Bronchoscopy revealed a yellowish to white polypoid, well-circumscribed mass. Treatment with potassium-titanyl-phosphate (KTP) laser ablation via flexible bronchoscope resulted in its complete resection. Histological findings showed smooth muscle cells without evidence of atypia or malignancy. These cells were positive for α-smooth muscle actin. We diagnosed primary bronchial leiomyoma. Subsequent follow-up examinations have shown no relapses for one year. KTP laser ablation via flexible bronchoscope is one of the useful options in the treatment of primary bronchial leiomyoma.
