Squamous Cell Papilloma:
Clinical:
The papilloma is the most common benign tracheal neoplasm in the adult. There is a strong association with cigarette smoking and the lesion probably occurs as a result of chronic irritation. The lesion can infiltrate and become malignant [2]. Treatment is endoscopic resection. On CT, the lesion is a small, non-calcified, well circumscribed nodule which projects into the bronchial (most common) or tracheal lumen.REFERENCES:
