Solitary endobronchial mixed papilloma with prominent micropapillary pattern: a case report
نویسندگان
چکیده
Mixed squamous cell and glandular papilloma (mixed papilloma) is a rare, benign, pulmonary neoplasm and most commonly found in senile patients with male predilection. There were only 18 cases reported so far in the English literature. We herein present one case of mixed papilloma in a 61-year-old male patient. Contrast-enhanced computed tomography scanning revealed a solitary nodule in the inferior lobe of left lung with the obstruction of basal segmental bronchus. Histologically, the glandular component of the mixed papilloma was characterized by the prominent “Medusa head-like” micropapillae and occupied more than 70% of the whole lesion. In the current case, these micropapillary patterns were so worrisome and should be distinguished with primary or metastatic micropapillary adenocarcinoma, especially in frozen slides or if the specimen is limited. By reporting this case, we aim to remind the pathologist with this uncommon histological structure in mixed papilloma.
