One case of a 58 years old woman is reported which was checked up with hemosputum and Rt-S4 atelc.tasit.ln chest X-ray film.<BR>Radiologically and endoscopically, there were some vague factors to determine as squamous cell carcinoma of maior bronchi, and it was diagnosed papilloma by transbronchial biopsy. Middle lobectomy was performed on 24 July, 1978.<BR>The pink v-white califlower like tumor is 0.7×0.7 cm in size, protruded on B4 and confined itself within bronchial wall. Microscopically, it consists of non-malignant papillary mucosal folds with a core of thin walled blood vessels and connective tissue.<BR>Usually, true benign solitary papilloma has malignant potentiality. This report illustrates the necessity of surgical resection for this lesion because it is difficult to diagnose benign lesion only by biopsied material.
