Abstract
A 64-year-old woman presented with an intractable cough and purulent sputum, and a
chest CT revealed a mass within the left lower lobar bronchial orifice. A flexible
bronchoscopy demonstrated a red, glistening, nodular single lesion, obstructing the
lumen of the left lower lobe of the bronchus, and biopsy of the specimen showed squamous
papilloma. Surgical resection was selected for the definite treatment, and a simple
left lower lobectomy was performed. Histopathological examination revealed a 1.2 × 1.0 cm
sized bronchial obstructing mass and the diagnosis of squamous papilloma was confirmed
with low p53, Ki-67 (less than 5 %) and focal weak positive CEA expression. The patient
had an uncomplicated postoperative course and remains asymptomatic 3 months afterwards.
